Microbotox for the treatment of wide facial pores: A promising therapeutic approach

"The efficacy and adverse effects of treatment options for facial pores: A review article"

INTRODUCTION

Skin pores are enlarged openings of the pilosebaceous follicles that can be affected by age, gender, genetics, exposure to UV light, ethnicity, and sebum secretion. Many treatment modalities reduce facial pores' count and area, including oral and topical medications as well as different wavelengths of lasers. Finding a safe and cost-effective treatment protocol is necessary since facial pores are one of the main reasons for cosmetic complaints.

AIM

This review compares available treatment options for reducing facial pores' number and area according to the published clinical trials.

METHODS

A search on PubMed and Google Scholar was performed. Nineteen published clinical trials regarding treatment options for facial pores were included and reviewed based on the authors' clinical experience.

RESULTS

A total number of 591 cases (83.7% female) aged 18-80 years were included. Three assessment methods including digital imaging, physician assessment, and patient' satisfaction were used in the studies to evaluate the therapeutic efficacy of each modality. Furthermore, combining different modalities increased the efficacy of reducing pores' size and number. Mild, reversible burning and erythema were common side effects.

CONCLUSION

Multiple sessions and combination therapies improve facial pores' area and number. In young patients, the focus should be on controlling sebum production, while in older patients, the focus should be on rejuvenation in addition to the control of sebum production.

Microbotox injection versus its topical application following microneedling in the treatment of wide facial pores: A split face comparative study

BACKGROUND

Enlarged facial pores and seborrhea are common cosmetic problems. Mesobotox has been proved to be effective safe therapeutic option.

OBJECTIVE

To compare the efficacy and longevity of intradermal mesobotox injection versus its topical application with microneedling for treatment of wide facial pores and seborrhea.

MATERIALS AND METHODS

This split face study was conducted on 20 patients with enlarged facial pores and seborrhea. One side of the face was treated with intradermal injection of botulinum toxin, the other was treated with its topical application following microneedling. Patient evaluation was performed after 1 month then after 4 months.

CONCLUSION

Microbotox can effectively and safely minimize enlarged facial pores with no downtime. Intradermal injection showed more patient satisfaction on the basis of greater efficacy, longevity of treatment than its topical application following microneedling.

Microbotox (Mesobotox) versus microneedling as a new therapeutic modality in the treatment of atrophic post-acne scars

BACKGROUND

Given that most patients with moderate to severe acne develop post-acne scars, many treatment modalities can be used to ameliorate scaring; chemical peels, surgical excision, dermabrasion, fat transfer, autologous collagen, punch grafting, diverse filler injection, and lasers. Microneedling is one of the promising modalities based on the breaking of dermis-damaged collagen and enhancing new collagen formation. Microbotox (Mesobotox) injection may have a beneficial effect by causing muscular paralysis with subsequent dermal edema due to transient and mild lymphatic insufficiency. The comparison between these two modalities has not been yet assessed. The aim of this study was to evaluate and compare the safety and efficacy of both methods (Microbotox and microneedling) in the treatment of atrophic post-acne scars.

METHODS

Between May 2021 to April 2022, patients with atrophic post-acne scars were selected from the out-patients clinics of the Department of Dermatology, Faculty of Medicine. The face was divided into two sides: the right side was treated with Mesobotox for three sessions once monthly and followed up 3 months later after the last session and the left side was treated with dermapen (microneedling) for six sessions every 2 weeks and followed up 3 months after the last session. The feasibility, safety, and efficacy of both lines of treatment were studied.

RESULTS

This study included 20 patients with atrophic post-acne scars. They were 13 females (65%) and 7 males (35%), and their ages ranged between 15 and 35 years with a mean ± sd age of 24.40 ± 5.90 based on the significant improvement between S1 (baseline acne scar score) and both S2 (acne scar score at end of treatment) and S3 (acne scar score 3 months after the last session). Microneedling showed also similar results to Mesobotox.

CONCLUSIONS

Microbotox and microneedling were effective and tolerated.

Split body comparative clinical and radiological study of fractional CO2 laser versus carboxytherapy in treatment of striae distensae

BACKGROUND

Striae Distensae (SD) are quite common complaint in dermatology practice. They are linear lesions of variable length and width according to the site and the causative condition. Several treatment modalities have been tried. To achieve satisfactory results, a combination therapy is often needed.

OBJECTIVES

To evaluate the efficacy and safety of fractional CO₂ laser versus carboxytherapy in the treatment of Striae Distensae clinically and radiologically.

METHODS

Thirty Egyptian patients with striae distensae, received a split body therapy: the left side was treated by fractional CO₂ laser and the right side was treated by carboxytherapy in the same session. Six sessions were done with 4 weeks apart. Clinical evaluation by measurement of the width of widest striae on both sides, global aesthetic improvement scale (GAIS) and Likert satisfaction scale. Radiological evaluation by measurement of cutaneous thickness of widest striae on both sides by ultrasonography.

RESULTS

There was a highly statistically significant decrease in the median width of the widest striae distensae on both sides after the last session (P < 0.01). Regarding GAIS, satisfaction scale and ultrasound, there was highly statistically significant improvement on laser side than carboxytherapy side (P < 0.01) after last session.

CONCLUSION

Both fractional CO₂ laser and carboxytherapy may be considered as safe and effective lines of treatment for striae distensae, but fractional CO₂ laser showed excellent improvement clinically, radiologically when compared with carboxytherapy which made it a promising module in treatment of striae distensae.

Microdroplet botulinum toxin: A review

Microbotox is the administration of multiple microdroplets of botulinum toxin in intradermal plane. It is increasingly becoming popular owing to its more favorable outcome and better safety profile than the conventional technique. The intention is to treat fine lines and wrinkles without imparting an undesired “frozen face like” appearance. Besides facial rejuvenation, it has found its way into the management of other indications such as rosacea, hyperhidrosis, keloid, and seborrhea. Being a relatively newer method, knowledge about the various dilution methods, desired volume, and correct depth of injection involved in this technique remain scarce. In this article, the authors have highlighted various indications, procedures, adverse effects, and contraindications of microbotox.

Botulinum Neurotoxin Type A in the Treatment of Facial Seborrhea and Acne: Evidence and a Proposed Mechanism

Intradermal injection of botulinum neurotoxin is a frequently performed procedure in aesthetic dermatology to improve facial skin tone, texture, fine wrinkles, and enlarged pores. In practice, botulinum neurotoxin type A is also used to reduce skin oiliness of the face. There is increasing evidence that acetylcholine plays specific roles in sebum production, suggesting that botulinum neurotoxin type A may reduce sebum production by interfering with cholinergic transmission between sebaceous glands and autonomic nerve terminals. Botulinum neurotoxins can also inhibit several pathogenetic components of acne development, suggesting that botulinum neurotoxins can be used as a safe and effective treatment modality for acne and other skin disorders related to overactivity of sebaceous glands. This review aims to explore the current evidence behind the treatment of facial seborrhea and acne with botulinum neurotoxin type A.

Fractional carbon dioxide laser versus carbon-assisted Q-switched Nd: YAG laser in the treatment of dilated facial pores

BACKGROUND

The treatment of dilated facial pores is difficult, and the ideal modality is not established yet. Different ablative and nonablative lasers have been used in the treatment of dilated pores with variable outcomes.

AIM

To evaluate and compare the efficacy of fractional CO2 laser versus carbon-assisted Q-switched Nd: YAG laser in dilated facial pores.

METHODS

The study included 80 patients with dilated pores divided into two groups each containing 40 patients. Group (A) had fractional CO2 laser treatment, and group (B) received Q-switched Nd: YAG laser treatment after the application of a carbon solution on the face. The treatment was repeated monthly for a total of 3 sessions. Objective and subjective assessments of the clinical outcome were performed.

RESULTS

Both modalities significantly improved the dilated pores; however, the clinical response was statistically higher and the improvement was maintained for a longer duration of time in the factional laser group compared with the carbon-assisted Q-switched Nd: YAG laser group (p = 0.01). The downtime was significantly lower in the Q-switched Nd: YAG laser group, and the patients' satisfaction rates were comparable in both groups.

CONCLUSION

The two laser systems appear to be effective, safe, and well-tolerated in the treatment of dilated pores. The fractional CO2 laser was associated with a significantly higher and more prolonged clinical response.
