Abstract
Melasma is a prevalent hyperpigmentation condition known for its challenging treatment due to its resemblance to photoaged skin disorders. Numerous studies have shed light on the intricate nature of melasma, which often bears similarity to photoaging disorders. Various therapeutic approaches, encompassing topical and systemic treatments, chemical peeling, and laser therapy, have exhibited efficacy in managing melasma in previous research. However, melasma often reoccurs despite successful treatment, primarily due to its inherent photoaged properties. Given that melasma shares features with photoaging disorders, including disruptions in the basement membrane, solar elastosis, angiogenesis, and mast cell infiltration in the dermal layer, a comprehensive treatment strategy is imperative. Such an approach might involve addressing epidermal hyperpigmentation while concurrently restoring dermal components. In this article, we provide a comprehensive review of conventional treatment methods frequently employed in clinical practice, as well as innovative treatments currently under development for melasma management. Additionally, we offer an extensive overview of the pathogenesis of melasma.

Abstract
Melasma is a chronic hyperpigmentation skin disorder that is more common in the female gender. Although melasma is a multifactorial skin disorder, however, sun-exposure and genetic predisposition are considered as the main etiologic factors in melasma occurrence. Although numerous topical and systemic therapeutic agents and also non-pharmacologic procedural treatments have been considered in melasma management, however, the commonly available therapeutic options have several limitations including the lack of sufficient clinical effectiveness, risk of relapse, and high rate of unwanted adverse drug reactions. Recruitment of nanotechnology for topical drug delivery in melasma management can lead to enhanced skin penetration, targeted drug delivery to the site of action, longer deposition at the targeted area, and limit systemic absorption and therefore systemic availability and adverse drug reactions. In the current review, first of all, the etiology, pathophysiology, and severity classification of melasma have been considered. Then, various pharmacologic and procedural therapeutic options in melasma treatment have been discussed. Afterward, the usage of various types of nanoparticles for the purpose of topical drug delivery for melasma management was considered. In the end, numerous clinical studies and controlled clinical trials on the assessment of the effectiveness of these novel topical formulations in melasma management are summarized.

Abstract
OBJECTIVE To examine the effectiveness of the ColorMeter DSM III (ColorMeter; Cortex Technology) at grouping individuals by skin tone and measuring erythema/skin discoloration after erythema induction across skin tones. METHODS This pre/post experimental study induced erythema on a convenience sample of 61 healthy adults. Skin tone at baseline was measured using the ColorMeter, Munsell Soil Color Chart 5YR (Munsell), and Pantone SkinTone Guide (Pantone) and compared with the Eumelanin Human Skin Colour Scale (Eumelanin Scale) groupings. Erythema and melanin values on the arm immediately and after recovery time were compared with baseline values. Melanin was measured at five body regions on the face and arm. RESULTS Participants were predominantly women (64% [n = 39] women, 36% [n = 22] men) and young (mean, 28.8 ± 14.3 years); 5% (n = 3) were Hispanic, 26% (n = 16) Asian, 29% (n = 18) Black, 38% (n = 23) White, and 7% (n = 4) identified with more than one race. ColorMeter lightness (L*) and melanin measures were strongly correlated with both Munsell and Pantone values. Munsell skin tone groups were not aligned with Eumelanin Scale groupings. Most participants were in the Eumelanin intermediate-low group, and this changed depending on which body location melanin value was used. The change in erythema from baseline did not differ significantly across skin tone groups at the ulnar head, but on the forearm at the delayed time point, significant differences existed between light and both medium and dark skin tone groups (P = .001; 95% CI, 0.04-0.37). CONCLUSIONS The ColorMeter provides an effective objective measure of skin tone and erythema/discoloration across various skin tones and may improve on current standards for detection. The proposed Eumelanin Scale-Modified provides additional sensitivity for persons with medium skin tones.

Abstract
BACKGROUND Melasma is an acquired, chronic pigmentary disorder predominantly affecting women. It may significantly affect quality of life and self-esteem due to its disfiguring appearance. Multiple treatments for melasma are available, with mixed results. OBJECTIVE The aim of this article was to conduct an evidence-based review of all available interventions for melasma. METHODS A systematic literature search of the PubMed electronic database was performed using the keywords 'melasma' and/or 'chloasma' in the title, through October 2018. The search was then limited to 'randomized controlled trial' and 'controlled clinical trial' in English-language journals. The Cochrane database was also searched for systematic reviews. RESULTS The electronic search yielded a total of 212 citations. Overall, 113 studies met the inclusion criteria and were included in this review, with a total of 6897 participants. Interventions included topical agents, chemical peels, laser- and light-based devices, and oral agents. Triple combination cream (hydroquinone, tretinoin, and corticosteroid) remains the most effective treatment for melasma, as well as hydroquinone alone. Chemical peels and laser- and light-based devices have mixed results. Oral tranexamic acid is a promising new treatment for moderate and severe recurrent melasma. Adverse events from all treatments tend to be mild, and mainly consist of skin irritation, dryness, burning, erythema, and post-inflammatory hyperpigmentation. CONCLUSIONS Hydroquinone monotherapy and triple combination cream are the most effective and well-studied treatments for melasma, whereas chemical peels and laser- and light-based therapies are equal or inferior to topicals, but offer a higher risk of adverse effects. Oral tranexamic acid may be a safe, systemic adjunctive treatment for melasma, but more studies are needed to determine its long-term safety and efficacy. Limitations of the current evidence are heterogeneity of study design, small sample size, and lack of long-term follow-up, highlighting the need for larger, more rigorous studies in the treatment of this recalcitrant disorder.

Abstract
BACKGROUND Melasma, a common acquired disorder of hyperpigmentation, especially in women, is often resistant to therapy. This study was aimed to evaluate the efficacy and safety of azelaic acid, resorcinol and phytic acid solution in chemical peeling of melasma in comparison to 50% glycolic acid. MATERIALS AND METHODS This clinical trial was performed, on 42 female patients with bilateral melasma. Severity of melasma was assessed by melasma area and severity index (MASI). Combination of (20% azelaic acid + 10% resorcinol + 6% phytic acid) was used as a new peeling agent on the right side of the face and 50% glycolic acid on the left side every 2 weeks for 6 times. Follow-up was carried out for 3 months after the last session. Any decrease in MASI score and unwanted complications following peeling were evaluated and compared during the trial. RESULTS Patients showed marked improvement as calculated with MASI score before and after treatment in both sides of the face. The efficacy of combination formula (azelaic acid, resorcinol and phytic acid) was similar to glycolic acid, but with fewer complications. There was no statistically difference in improvement between two groups (P > 0.05). However, the patient's discomfort following procedures was significantly lower with azelaic acid, resorcinol and phytic compared with the glycolic acid peels (P < 0.05) and there was the same duration in the beginning of the therapeutic response in both groups. CONCLUSION Results showed that triple-combination was found to be an effective and safe peeling agent in the treatment of melasma and it was as effective as 50% glycolic acid peel.

Abstract
BACKGROUND Melasma is acquired symmetric hypermelanosis characterized by light-to-deep brown pigmentation over cheeks, forehead, upper lip, and nose. Treatment of this condition is difficult and associated with high recurrence rates. Chemical peels have become a popular modality in the treatment of melasma. OBJECTIVE To compare the therapeutic efficacy and tolerability of glycolic acid (35%) versus salicylic-mandelic (SM) acid (20% salicylic/10% mandelic acid) versus phytic combination peels in Indian patients with melasma. MATERIALS AND METHODS Ninety patients diagnosed with melasma were randomly assigned into 3 groups of 30 patients each. Group A received glycolic acid (GA-35%) peel, Group B received SM acid, and Group C received phytic combination peels. Each group was primed with 4% hydroquinone and 0.05% tretinoin cream for 4 weeks before treatment. Chemical peeling was done after every 14 days in all groups until 12 weeks. Clinical evaluation using melasma area and severity index (MASI) score and photography was recorded at every visit and follow-up was done until 20 weeks. RESULTS There was a decrease in MASI score in all 3 groups but it was statistically significantly lower in Group A than Group C (p = .00), and it was also statistically significantly lower in Group B than Group C (p = .00) but there was no statistically significant difference between Groups A and B (p = .876). Objective response to treatment evaluated by reduction in MASI scoring after 12 weeks was 62.36% reduction in GA group, 60.98% reduction in SM group, and 44.71% in phytic acid group. CONCLUSION It is concluded that GA (35%) and SM acid peels are both equally efficacious and a safe treatment modality for melasma in Indian skin, and are more effective than phytic acid peels. Salicylic-mandelic peels are better tolerated and more suitable for Indian skin.

Abstract
AIMS To assess the feasibility of classifying skin tone using Munsell color chart values and to compare Munsell-based skin tone categories to ethnicity/race to predict pressure ulcer risk. BACKGROUND Pressure ulcer classification uses level of visible tissue damage, including skin discoloration over bony prominences. Prevention begins with early detection of damage. Skin discoloration in those with dark skin tones can be difficult to observe, hindering early detection. DESIGN Observational cohort of 417 nursing home residents from 19 nursing homes collected between 2009-2014, with weekly skin assessments for up to 16 weeks. METHODS Assessment included forearm and buttocks skin tone based on Munsell values (Dark, Medium, Light) at three time points, ethnicity/race medical record documentation, and weekly skin assessment on trunk and heels. RESULTS Inter-rater reliability was high for forearm and buttock values and skin tone. Mean Munsell buttocks values differed significantly by ethnicity/race. Across ethnicity/race, Munsell value ranges overlapped, with the greatest range among African Americans. Trunk pressure ulcer incidence varied by skin tone, regardless of ethnicity/race. In multinomial regression, skin tone was more predictive of skin damage than ethnicity/race for trunk locations but ethnicity/race was more predictive for heels. CONCLUSIONS Given the overlap of Munsell values across ethnicity/race, color charts provide more objective measurement of skin tone than demographic categories. An objective measure of skin tone can improve pressure ulcer risk assessment among patients for whom current clinical guidelines are less effective.

Abstract
Background: Numerous therapeutic options have been tried in the management of melasma. Aims and Objectives: This prospective randomized study was planned to assess the efficacy of low potency triple combination (TC) cream (TC-hydroquinone 2%/tretinoin 0.05%/fluocinolone 0.01%) versus glycolic acid (GA) peels/azelaic acid (AA) 20% cream (GA/AA) combination in melasma. Materials and Methods: Forty patients with melasma were recruited into this study and randomized into two groups. Group A consisting 20 patients received TC cream once a day for night time application for 3 months. Group B comprising of 20 patients received GA/AA 20% cream combination for 3 months. The disease severity was monitored with digital photography, melasma area and severity index (MASI) score, which was calculated at baseline, 6 weeks and 12 weeks, and visual analog scale (VAS) score, which was calculated at baseline and 12 weeks. Results: Of 40 patients, 38 were completed the study. A significant reduction in MASI and VAS was recorded after 6 weeks and 12 weeks of treatment in both groups A and B (P = 0.001). However, there was no significant difference in the mean MASI scores between the two groups at baseline, 6 weeks and 12 weeks. Similarly, there was no difference in the mean VAS scores between the two groups at baseline and 12 weeks. Four patients in group A and 3 in group B experienced adverse effects such as irritation, dryness, and photosensitivity. Conclusion: Both low potency TC cream and GA/AA 20% cream combination are effective in treating melasma among Indian patients.

Abstract
Introduction Melasma is one of the most common pigmentary disorders seen by dermatologists and often occurs among women with darker complexion (Fitzpatrick skin type IV–VI). Even though melasma is a widely recognized cause of significant cosmetic disfigurement worldwide and in India, there is a lack of systematic and clinically usable treatment algorithms and guidelines for melasma management. The present article outlines the epidemiology of melasma, reviews the various treatment options along with their mode of action, underscores the diagnostic dilemmas and quantification of illness, and weighs the evidence of currently available therapies. Methods A panel of eminent dermatologists was created and their expert opinion was sought to address lacunae in information to arrive at a working algorithm for optimizing outcome in Indian patients. A thorough literature search from recognized medical databases preceded the panel discussions. The discussions and consensus from the panel discussions were drafted and refined as evidence-based treatment for melasma. The deployment of this algorithm is expected to act as a basis for guiding and refining therapy in the future. Results It is recommended that photoprotection and modified Kligman’s formula can be used as a first-line therapy for up to 12 weeks. In most patients, maintenance therapy will be necessary with non-hydroquinone (HQ) products or fixed triple combination intermittently, twice a week or less often. Concomitant camouflage should be offered to the patient at any stage during therapy. Monthly follow-ups are recommended to assess the compliance, tolerance, and efficacy of therapy. Conclusion The key therapy recommended is fluorinated steroid containing 2–4% HQ-based triple combination for first line, with additional selective peels if required in second line. Lasers are a last resort. Electronic supplementary material The online version of this article (doi:10.1007/s13555-014-0064-z) contains supplementary material, which is available to authorized users.

Abstract
Chemical peels have been time-tested and are here to stay. Alpha-hydroxy peels are highly popular in the dermatologist’s arsenal of procedures. Glycolic acid peel is the most common alpha-hydroxy acid peel, also known as fruit peel. It is simple, inexpensive, and has no downtime. This review talks about various studies of glycolic acid peels for various indications, such as acne, acne scars, melasma, postinflammatory hyperpigmentation, photoaging, and seborrhea. Combination therapies and treatment procedure are also discussed. Careful review of medical history, examination of the skin, and pre-peel priming of skin are important before every peel. Proper patient selection, peel timing, and neutralization on-time will ensure good results, with no side effects. Depth of the glycolic acid peel depends on the concentration of the acid used, the number of coats applied, and the time for which it is applied. Hence, it can be used as a very superficial peel, or even a medium depth peel. It has been found to be very safe with Fitzpatrick skin types I–IV. All in all, it is a peel that is here to stay.

Abstract
BACKGROUND Melasma is an acquired disorder of hyperpigmentation occurring on the face and predominantly affecting women of childbearing age. It is a chronic, often relapsing condition with a negative impact on quality of life. Current treatments for melasma are unsatisfactory. OBJECTIVE The aim of this article was to conduct an evidence-based review of interventions available for the treatment of melasma. METHODS A systematic literature search was performed using PubMed and the keywords 'melasma' or 'chloasma' in the title. The search was further refined by using a filter for 'controlled clinical trials' and 'randomized controlled trial'. The included studies were used to develop recommendations for treatment. RESULTS The electronic search yielded a total of 80 citations. Forty studies were included in this review, which had a total of 2,912 participants. Three different therapeutic modalities were investigated-topical agents, chemical peels, and laser and light therapies. Topical depigmenting agents were found to be the most effective in treating moderate-to-severe melasma, with combination therapies, such as triple-combination therapy (hydroquinone, tretinoin, and fluocinolone acetonide), yielding the best results. Chemical peels as well as laser and light therapies were found to have moderate benefit but more studies are needed to determine their efficacy and long-term safety. Adverse events associated with treatment were mild and short-lasting and included skin irritation, dryness, burning, and erythema. The data could not be statistically pooled because of the heterogeneity of treatments and lack of consistency across study designs. CONCLUSIONS Topical combination therapies were found to be more effective than monotherapy. Triple combination therapy was found to be the most effective, but approximately 40 % of patients develop erythema and peeling. Chemical peels and laser and light therapies produced mixed results, with increased risk of irritation and subsequent hyperpigmentation, particularly in darker-skinned individuals. Hence, current treatments available for melasma remain unsatisfactory. Many of the studies lacked long-term follow-up. Limitations of current literature include the heterogeneity of study designs, small sample sizes, and poor follow-up rates. Additional evidence for the effects and role of sunscreens is needed. Categorization or stratification of demographic data should also be included in future studies, such as age, melasma type, and duration of melasma prior to initiation of treatment. Patient's perception of improvement versus investigator's assessment of improvement should also be included in future studies and standardized methods of study design and assessment of outcomes are needed to form definitive conclusions on the efficacy of different treatment modalities.

Abstract
Melasma is a common disorder of hyperpigmentation, which has a severe impact on the quality of life. Inspite of tremendous research, the treatment remains frustrating both to the patient and the treating physician. Dark skin types (Fitzpatrick types IV to VI) are especially difficult to treat owing to the increased risk of post-inflammatory hyperpigmentation (PIH). The treatment ranges from a variety of easily applied topical therapies to agents like lasers and chemical peels. Peels are a well-known modality of treatment for melasma, having shown promising results in many clinical trials. However, in darker races, the choice of the peeling agent becomes relatively limited; so, there is the need for priming agents and additional maintenance peels. Although a number of new agents have come up, there is little published evidence supporting their use in day-to -day practice. The traditional glycolic peels prove to be the best both in terms of safety as well as efficacy. Lactic acid peels being relatively inexpensive and having shown equally good results in a few studies, definitely need further experimentation. We also recommend the use of a new peeling agent, the easy phytic solution, which does not require neutralisation unlike the traditional alpha-hydroxy peels. The choice of peeling agent, the peel concentration as well as the frequency and duration of peels are all important to achieve optimum results.

Abstract
This paper describes recent data on the effects of various skin formulations containing hydroxyacids (HAs) and related products on sun-exposed skin. The most frequently used classes of these products, such as α- and β-hydroxyacids, polyhydroxy acids, and bionic acids, are reviewed, and their application in cosmetic formulations is described. Special emphasis is devoted to the safety evaluation of these formulations, particularly on the effects of their prolonged use on sun-exposed skin. We also discuss the important contribution of cosmetic vehicles in these types of studies. Data on the effects of HAs on melanogenesis and tanning are also included. Up-to-date methods and techniques used in those explorations, as well as selected future developments in the cosmetic area, are presented.

Abstract
BACKGROUND Melasma still presents as a difficult entity to treat, especially in the Asian skin phe-notype. Recently laser toning with the Q-switched Nd:YAG has attracted attention. The present study investigated the efficacy of Q-switched Nd:YAG laser toning for melasma, with a histopathological comparison with the Q-switched ruby laser. SUBJECTS AND METHODS Eight Japanese females (41-57 yr, mean 52.5 yr) with Fitzpatrick skin type III and bilateral melasma participated in the study. One half of each subject's face (randomly chosen) was treated with Q-switched 1064 nm Nd:YAG laser toning (pulse width 5-20 ns; spot size, 6 mm diameter; fluence, 3.0 J/cm(2), 5-7 passes, once/week, 4 weeks: QS:YAG group), and the contralateral half with a single treatment using a Q-switched ruby laser (694.5 nm, pulse width 20 ns, spot size 4 mm diameter; fluence 4.0 J/cm2, 1 pass with approximately 20% overlap: QS:Ruby group). Skin biopsies were taken immediately after the 4(th) Nd:YAG session and the single ruby session, and histopathological comparison was performed with light- and transmission electron microscopy (TEM). RESULTS Improvement in melasma pigmentation was seen in both the QS:YAG- and QS:Ruby-treat-ed sides, and this was well-maintained in the QS:YAG group. Ultrastructurally, melanin granules were destroyed in both groups, but there was considerably more morphological epidermal and dermal damage in the QS:Ruby specimens compared with minimal epidermal disruption and cellular damage in the QS:YAG specimens. CONCLUSIONS Q-switched 1064 nm Nd:YAG laser toning offered superior results in the treatment of melasma in the Japanese skin type compared with the Q-switched ruby laser, both ultrastructurally with less immediately post-treatment cellular damage and macroscopically, and a longer recurrence-free interval.

Abstract
Chemical peeling implies the application of a chemical agent to the skin, which causes controlled destruction of a part or the entire epidermis, with or without the dermis, leading to exfoliation and removal of superficial lesions, followed by regeneration of new epidermal and dermal tissues. The present study was directed toward safety concerns associated with superficial chemical peeling with glycolic acid (GA) in different concentrations at patients with acne tip I. A sample of 90 patients of either sex, aged between 17 to 21 years, were included in the study and submitted to superficial chemical peeling for acne vulgaris. The study lasted eight weeks and peeling sessions were carried out in each patient. Tolerance to the procedure and any undesirable effects noted during these sessions were recorded. For data statistical analysis and interpretation of results, software program "SPSS version 13" was used. Results were expressed through the descriptive statistics, as simple frequencies and percentages, while for establishing of statistically significant differences, in use was Friedman's test of significance. Almost all the patients tolerated the procedure well. Of totally 90 patients, only six, at the end of therapy experienced hard erythema, only ten, at the end of therapy experienced hard desquamation and only eleven, at the end of therapy experienced hard sensation of pulling of facial skin. Chemical peeling with glycolic acid is a well tolerated and safe treatment modality in acne type I.

Abstract
BACKGROUND Melasma is an acquired symmetrical pigmentary disorder where confluent grey-brown patches typically appear on the face. Available treatments for melasma are unsatisfactory. OBJECTIVES To assess interventions used in the management of all types of melasma: epidermal, dermal, and mixed. SEARCH STRATEGY In May 2010 we searched the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (Clinical Trials) in The Cochrane Library, MEDLINE, EMBASE, PsycINFO, and LILACS. Reference lists of articles and ongoing trials registries were also searched. SELECTION CRITERIA Randomised controlled trials that evaluated topical and systemic interventions for melasma. DATA COLLECTION AND ANALYSIS Study selection, assessment of methodological quality, data extraction, and analysis was carried out by two authors independently. MAIN RESULTS We included 20 studies with a total of 2125 participants covering 23 different treatments. Statistical pooling of the data was not possible due to the heterogeneity of treatments. Each study involved a different set of interventions. They can be grouped into those including a bleaching agent such as hydroquinone, triple-combination creams (hydroquinone, tretinoin, and fluocinolone acetonide), and combination therapies (hydroquinone cream and glycolic acid peels), as well as less conventional therapies including rucinol, vitamin C iontophoresis, and skin-lightening complexes like Thiospot and Gigawhite.Triple-combination cream was significantly more effective at lightening melasma than hydroquinone alone (RR 1.58, 95% CI 1.26 to 1.97) or when compared to the dual combinations of tretinoin and hydroquinone (RR 2.75, 95% CI 1.59 to 4.74), tretinoin and fluocinolone acetonide (RR 14.00, 95% CI 4.43 to 44.25), or hydroquinone and fluocinolone acetonide (RR 10.50, 95% CI 3.85 to 28.60).Azelaic acid (20%) was significantly more effective than 2% hydroquinone (RR 1.25, 95% CI 1.06 to 1.48) at lightening melasma but not when compared to 4% hydroquinone (RR 1.11, 95% CI 0.94 to 1.32).In two studies where tretinoin was compared to placebo, participants rated their melasma as significantly improved in one (RR 13, 95% CI 1.88 to 89.74) but not the other. In both studies by other objective measures tretinoin treatment significantly reduced the severity of melasma.Thiospot was more effective than placebo (SMD -2.61, 95% CI -3.76 to -1.47).The adverse events most commonly reported were mild and transient such as skin irritation, itching, burning, and stinging. AUTHORS' CONCLUSIONS The quality of studies evaluating melasma treatments was generally poor and available treatments inadequate. High-quality randomised controlled trials on well-defined participants with long-term outcomes to determine the duration of response are needed.

Abstract
Treatment of hyperpigmentation disorders can be a lengthy process. There are several topical treatment options and hydroquinone is the most frequently used. Both combination and monotherapy are employed. These treatment options apply primarily to epidermal hyperpigmentation disorders. Dermal hyperpigmentation disorders cannot yet be effectively managed with currently available therapeutic approaches. Cosmetic disfigurement caused by hypomelanosis, especially vitiligo, can constitute a serious impairment for the patient. So far there is no definitive remedy. Better cosmetic results are generally reported for combination therapies.

Abstract
OBJECTIVE/AIM To examine approaches to therapy for melasma in Latin Americans and to propose treatment algorithms for patients with mild, moderate and severe melasma. BACKGROUND Melasma is prevalent in up to 10% of the Latin American population. It is found in all racial groups and is more common in subjects with darker skin phototypes. A number of topical treatments and procedures have been used for melasma. Topical treatments containing hydroquinone are the most popular. Care must be taken when treating melasma to avoid inducing post-inflammatory hyperpigmentation and ochronosis. Determination of the severity of melasma (using the Melasma Area Severity Index and/or Physician's Global Assessment) and choice of the most effective and suitable treatment and/or procedure for individual patients is therefore essential. Sun protection is mandatory for all melasma patients. METHODS Thirty-one clinical studies of topical treatments, chemical peels and laser and other therapies used for treating melasma were assessed for the level and quality of clinical evidence, by the Latin American Pigmentary Disorders Academy. The results of this analysis were combined with differential diagnosis guidelines and methods for assessing treatment success to establish algorithms for treating mild and moderate-to-severe melasma. RESULTS The most appropriate first-line treatment for mild melasma is hydroquinone 4%, triple combination cream containing hydroquinone 4%, tretinoin 0.05% and fluocinolone acetate 0.01%, double combination (e.g. 4% hydroquinone and 0.1% tretinoin) or non-phenolic therapy where there is an allergy to compounds. In moderate-to-severe melasma, triple combination cream is the recommended first-line treatment. Second-line treatment is double combination or hydroquinone 4% where triple therapy is not available or if allergic to compounds. Sun avoidance measures and broad spectrum sunscreens with high SPF are fundamental for the successful management of the disease.

Abstract
BACKGROUND Melasma is a common disfiguring skin problem. Multiple modalities have been used in the treatment of melasma, such as bleaching agents and chemical peels. Many chemicals have been used in the skin peeling for melasma, such as Jessner's solution and glycolic acid. Lactic acid is an alpha-hydroxy acid that has not been used before in chemical peeling of melasma. OBJECTIVE The purpose of the present work is to evaluate the efficacy and safety of lactic acid in chemical peeling of melasma. METHODS This study was conducted at the outpatient Department of Dermatology and Venereology, Baghdad Teaching Hospital, in the period between April 2001 and August 2002. Twenty patients with melasma were included in this study; 18 (90%) were female and 2 (10%) were male, with an age range from 24 to 38 years and a mean of 29 +/- 4.264 SD. Full clinical examination was done of all patients, including Wood's light. The severity of melasma was assessed by the Melasma Area Severity Index (MASI). Pure lactic acid, full strength (92%; pH 3.5), was used as a new peeling agent. The chemical peeling sessions were done every 3 weeks until the desired response was achieved, but not more than six sessions. Follow-up was carried out for 6 months after the last session. All patients had skin type IV; morphologic forms of melasma were a mask-like shape in seven patients (35%), a butterfly shape in nine patients (45%), and a horseshoe shape in 4 patients (20%). RESULTS Eight patients defaulted from the study after the first session for unknown reasons. Twelve patients completed the study. Eleven patients were female (91.7%), and one patient was male (8.3%). Their ages ranged from 24 to 38 years, with a mean of 29.25 +/- 4.9 SD. Wood's light examination showed increased contrast in all patients (epidermal melasma). The number of sessions ranged from two to six. All 12 patients showed marked improvement, as calculated by the MASI score before and after treatment, and the response was highly statistically significant. No side effect was recorded in all treated patients. CONCLUSION Lactic acid was found to be a new effective and safe peeling agent in the treatment of melasma.

Abstract
Alterations in skin pigmentation may often have a dramatic expression in individuals with a dark skin complexion and can be a source of significant emotional distress in these individuals. Hyperpigmented disorders such as melanosis (melasma), post-inflammatory hyperpigmentation, drug-induced hyperpigmentation, and erythema dyschromicum perstans tend to have a prolonged course and, in many cases, are refractory to treatment, further contributing to the psychological impairment of the affected patients. Melanosis, is a common form of facial pigmentation attributable to sunlight and hormonal factors. A range of treatment modalities, such as depigmenting agents, topical retinoids, and chemical peels in conjunction with rigorous sun protection, can improve the melanosis but the condition usually recurs. Combination regimens, including frequent applications of superficial- and medium-depth chemical peels, appear to be particularly effective and well tolerated in dark-skinned patients with melanosis. Post-inflammatory hyperpigmentation is the result of excess pigment deposition following an inflammatory skin disorder. Topical tretinoin, hydroquinone, azelaic acid, kojic acid, and glycolic acid peels have been employed with variable degrees of success. Drug-induced pigmentation is a frequent cause of acquired hypermelanosis, its clinical expression depending on the triggering molecule and the underlying pathogenetic mechanism. Identifying and discontinuing the offending agent is the main approach in this condition, although, recent reports have demonstrated the efficacy of Q-switched lasers in accelerating the pigment removal. Erythema dischromicum perstans is a characteristic dermal pigmentation occurring mainly in dark-skinned individuals. Immunomodulating agents, such as clofazimine and dapsone have been shown to lighten this disorder, although, the exact mode of action is not clear.

Abstract
Alpha-hydroxy acids (AHAs) such as glycolic acid (GA) and lactic acid (LA) have been reported to be effective in treating pigmentary lesions such as melasma, solar lentigines, and postinflammatory hyperpigmentation. The mechanism of this effect might be due to epidermal remodeling and accelerated desquamation, which would result in quick pigment dispersion. However, the direct effect of AHAs on melanin synthesis has not yet been well studied. To elucidate such a direct effect of AHAs on melanogenesis, we performed melanin assays, growth curve determinations, Northern and Western blotting for melanogenic proteins [tyrosinase, tyrosinase related protein (TRP)-1 and TRP-2], and tyrosinase and, 4-dihydroxyphenylalaninechrome tautomerase enzyme activity assays using mouse B16 and human melanoma cells. GA or LA (at doses of 300 or 500 microg/ml) inhibited melanin formation in similar dose-dependent manner, without affecting cell growth. Although the mRNA and protein expression or molecular size of tyrosinase, TRP-1 and TRP-2 were not affected, tyrosinase activity was inhibited. To see whether GA and/or LA directly inhibit tyrosinase catalytic function, the effect of GA and LA on human tyrosinase purified from the melanosome-rich large granule fraction of human melanoma cells was performed. GA or LA were shown to inhibit tyrosinase enzyme activity directly, but this effect was not due to the acidity of GA or LA, because adjusting the pH to 5.6 (the pH of GA and LA at concentrations of 2500 microg/ml), did not affect tyrosinase activity. Taken together, these results show that GA and LA suppress melanin formation by directly inhibiting tyrosinase activity, an effect independent of their acidic nature. GA and LA might work on pigmentary lesions not only by accelerating the turnover of the epidermis but also by directly inhibiting melanin formation in melanocytes.

Abstract
alpha-Hydroxy acid (AHA) peels and home regimens have recently been recognized as important adjunctive therapy in a variety of conditions including photodamage, actinic damage, melasma, hyperpigmentation disorders, acne, and rosacea. Overall in our experience and in the literature, AHAs have a proven level of safety and efficacy in a variety of skin types. Although their exact mechanism of action is unknown, it has been demonstrated that AHAs improve these disorders by thinning the stratum corneum, promoting epidermolysis, dispersing basal layer melanin, and increasing collagen synthesis within the dermis. In patients with photodamage, AHA peels and topical products are often combined with retinoids and other antioxidants for maximum benefit. Similarly, synergistic effects of fluorouracil and glycolic acid are observed in the treatment of diffuse actinic keratoses. For patients with melasma, AHA peels and combination products containing bleaching agents such as hydroquinone, kojic acid, and glycolic acid seem to have increased efficacy. Acne and rosacea patients can see improved results when standard regimens like antibacterials and topical retinoids are supplemented with AHA peels and lotions. However, care should always be taken prior to commencing treatment with AHA peels and topical products. By obtaining a thorough history and physical examination, the physician will identify any specific factors like medications, prior procedures and medical conditions which can affect the outcome of the peel. During the interview, there should be open discussion of patient questions and concerns so that realistic expectations can be made. Pre- and post-peel regimens should also be reviewed in full as patient compliance is essential to ensure the success of a series of AHA peels.

Abstract
BACKGROUND There is a dearth of published data regarding chemical peels in darker racial-ethnic groups. OBJECTIVE The purpose of the present investigation was to assess the clinical efficacy and safety of a new superficial salicylic acid peel in individuals of skin types V and VI. METHODS Twenty-five patients were included in this pilot investigation. Nine had acne vulgaris, 5 had post-inflammatory hyperpigmentation, 6 had melasma, and 5 had rough, oily skin with enlarged pores. The patients were pre-treated for 2 weeks with hydroquinone 4% prior to undergoing a series of five salicylic acid chemical peels. The concentrations of salicylic acid were 20% and 30%. The peels were performed at 2 week intervals. RESULTS. Moderate to significant improvement was observed in 88% of the patients. Minimal to mild side effects occurred in 16%. CONCLUSION The results of this study suggest that superficial salicylic acid peels are both safe and efficacious for treatment of acne vulgaris, oily skin, textural changes, melasma, and post-inflammatory hyperpigmentation in patients with skin types V and VI.
