Use of Radiesse in Combination With Restylane for Facial Augmentation

The Hybrid Filler Technique: A 5-Year Retrospective Analysis

BACKGROUND

The combination of calcium hydroxylapatite (CaHA) and hyaluronic acid fillers (CPM-HA, cohesive polydensified matrix-based hyaluronic acid fillers, Belotero® range, Merz Pharmaceuticals GmbH, Frankfurt, Germany), known as hybrid fillers, has emerged as a popular approach in aesthetic medicine. Premixed CaHA with CPM-HA offers several advantages, including enhanced tissue elevation and reduced early volume loss after injection.

OBJECTIVE

The objective of the present study is to assess the safety of premixing CaHA and CPM-HA fillers for rejuvenation purposes or as an aesthetic harmonization treatment.

METHODS

This retrospective study presents the clinical experience of two expert injectors who consistently used premixed CaHA and CPM-HA fillers for aesthetic treatments between March 2018 and December 2023. The premixed hybrid formulation was standardized and administered following a published protocol. A total of 2112 patients were treated, with meticulous follow-up over a minimum of one year.

RESULTS

In the 2112 patients treated, only 5 minor adverse events (0.24%) were reported. The adverse events consisted of 4 non-inflammatory nodules of which 2 completely resolved with hyaluronidase, and 1 case of transient edema. Secondary findings consist of the treated areas, type of CPM-HA used and mixing ratios that were applied.

CONCLUSION

The results from the current retrospective study, with the largest published cohort so far, are consistent with prior publications and strongly support a good safety profile of the CaHA:CPM-HA hybrid blend.

Jawline Sharp Contouring With Hybrid Filler

BACKGROUND

Having a well-defined jawline is a sign of youth and attractiveness among both men and women. Soft tissue fillers, such as calcium hydroxylapatite (CaHA) and hyaluronic acid (HA) fillers, offer nonsurgical alternatives for rejuvenating the lower face and enhancing the jawline. The aim of this study was to investigate the use of a premixed combination of HA with cohesive polydensified matrix technology (CPM, Belotero Intense, CPM-I) and CaHA to create a sharply defined jawline.

METHODS

A total of 126 patients were enrolled in the study and treated with a premixed combination of CPM-I and CaHA using a retrograde fanning injection technique with cannulas. The injection volumes and product ratios were customized according to the patients' needs.

RESULTS

The cohort consisted of 75 females and 51 males. The average injected volume of premixed CaHA:CPM-I was 5.83 mL. In the majority of patients, a 1:1 syringe ratio of CaHA:CPM-I was applied (n = 81, 64.2%). No adverse events were reported during the 6-month follow-up period.

CONCLUSION

The hybrid filler approach investigated in this study shows promise for achieving well-defined, long-lasting jawline contours.

A Systematic Review on the Effectiveness and Safety of Combining Biostimulators with Botulinum Toxin, Dermal Fillers, and Energy-Based Devices

INTRODUCTION

Aesthetic medicine has evolved towards minimally invasive procedures, with biostimulators like Poly-L-Lactic Acid (PLLA), Calcium Hydroxylapatite (CaHA), and Polycaprolactone (PCL) gaining attention for their role in collagen induction, improving skin texture, elasticity, and volume. Combining these agents with other treatments-such as botulinum toxin, dermal fillers, and energy-based devices (e.g. laser and radiofrequency therapies)-is hypothesised to provide enhanced aesthetic outcomes. However, studies on the efficacy and safety of these combinations remain sparse and methodologically varied, posing challenges in establishing definitive recommendations.

METHODS

This systematic review adhered to PRISMA guidelines, involving a thorough literature search across PubMed, MEDLINE, Embase, and Cochrane databases. The search included terms related to biostimulators and combination treatments. Studies meeting inclusion criteria reported clinical outcomes of combined biostimulator treatments, including effectiveness, safety, patient satisfaction, and adverse effects. Key parameters extracted included treatment area, combination protocols, and outcomes. Data synthesis used a narrative approach due to variability in methodologies, treatment protocols, and outcome metrics.

RESULTS

Out of 1,237 studies initially identified, 29 met the inclusion criteria. These studies included various combinations of biostimulators with botulinum toxin, dermal fillers, and energy-based devices, with sample sizes ranging from 10 to 350 subjects. Treatments combining CaHA or PLLA with energy-based modalities like high-intensity focused ultrasound (HIFU), fractional lasers, and microneedling demonstrated notable improvements in skin texture, elasticity, and contouring, particularly in areas with ageing signs. Adverse events included erythema, bruising, and nodules in 15-30% of cases, with rare but severe complications such as granulomas and vascular occlusions. Management protocols for these events involved corticosteroids, hyaluronidase, or surgical intervention. The review also found a lack of molecular understanding of the synergistic mechanisms.

CONCLUSION

The review underscores the potential benefits of combined treatments in aesthetic outcomes, though limitations like heterogeneous methodologies, small sample sizes, and inconsistent protocols impact the reliability of findings. Current literature lacks a molecular understanding of the mechanisms underlying these combinations, limiting insights into the longevity and safety of results. Future studies with standardised protocols, objective outcome measures, and detailed molecular analyses are essential for developing evidence-based recommendations for combining biostimulators with other treatments in aesthetic practice.

Evaluation of the attractiveness of lips with different volumes after filling with hyaluronic acid

To compare the attractiveness of lips with different volumes after filling in the view of laypersons, dentists, and specialists. The sample comprised close-up frontal and lateral photographs of the lips of 16 women who underwent lip filling procedure with hyaluronic acid and was divided into 2 groups. Group 1: eight women with thinner lips at pretreatment. Group 2: eight female patients with thicker lips at pretreatment. Photographs from before and 10 days after lip filling were used to assess attractiveness randomly displayed in a Google Forms questionnaire and then sent via a messaging app to the evaluators. The evaluators' groups were general dentists, dentists with degrees in facial aesthetics, and laypersons. The attractiveness was evaluated with scores from 0 to 10 (0: least attractive and 10 the greatest). T-tests were used for the statistical comparisons. The group with thinner lips showed significantly improved attractiveness after filling. The group with thicker lips showed a worsening attractiveness after filling. The group with thicker lips had significantly higher attractiveness scores than those with thinner lips. There was no significant difference in the preference between men and women. The group of laypersons was more rigorous, giving significantly lower lip attractiveness scores. Thinner lips showed a significant improvement in attractiveness after filling. Thicker lips showed a worsening of the attractiveness score after filling. Before and after filling, thicker lips had significantly higher attractiveness scores than thinner lips.Clinical relevance: The amount of fillers applied to each patient must be individually evaluated.

Combining Calcium Hydroxylapatite and Hyaluronic Acid Fillers for Aesthetic Indications: Efficacy of an Innovative Hybrid Filler

Background

Limited data are available describing effectiveness of combining the use of calcium hydroxylapatite (CaHA) and hyaluronic acid (HA).

Methods

The authors performed a retrospective chart review of patients injected with a premixed combination of CaHA and a cohesive polydensified matrix (CPM^®) HA (CaHA:CPM-HA ) in the authors’ aesthetic practices. The midface and lower face were injected. Patients’ records were evaluated, and treatment results were scored using the Merz Aesthetics Scale for the jawline^® (clinician rated, CR-MASJ). Adverse events were recorded.

Results

A total of 41 patients were included, all females with a mean age of 47.5 years (range 21–63 years). The mean CR-MASJ score improved from 2.12 at baseline to 0.68 at t = 3 months (SD = 0.69, 95% CI 1.28–1.60) and 1.27 at t = 12 months (SD = 0.74, 95% CI 0.43–0.74). 100% of the subjects had experienced a ≥1-point improvement in CR-MASJ score at t = 3 months, versus 85% at t = 12 months. No adverse events were reported.

Conclusion

The results of this study support the volumizing and lifting potential of the hybrid mix CaHA:CPM-HA for treatment of cheeks and jawline.

A Hybrid Filler: Combining Calcium Hydroxylapatite and Hyaluronic Acid Fillers for Aesthetic Indications

Limited data are available describing the use of calcium hydroxylapatite (CaHA) and hyaluronic acid (HA) in combination. The aim of this study is to investigate the safety of premixing CaHA and HA fillers before injection. The authors performed a retrospective chart review of patients injected with a premixed combination of CaHA and a cohesive polydensified matrix (CPM®) HA in the authors’ aesthetic practices. Patients records were evaluated for adverse events at 1-3 month, 5-7 month and >12-month posttreatment follow-up visits. The retrospective chart review identified 134 patients who had been treated with premixed CaHA: HA, most of whom were female (95%). Most patients were treated for multiple facial areas. Injections were subcutaneous and performed with 25G 38- or 50-mm cannulas, using a fanning injection technique. Injection volumes and product ratios depended on the number of areas being treated and severity of the aesthetic defect. Only 2 adverse events were reported which comprised slight cases of overcorrection at 1-3 months, both of which resolved with hyaluronidase. No other adverse events were reported. This combined evaluation of the published literature and retrospective examination of case reports raised no concerns about the use of premixed CaHA and CPM-HA (Hybrid) fillers for the treatment of a range of facial aesthetic indications.

Facial Rejuvenation Using a Mixture of Calcium Hydroxylapatite Filler and Hyaluronic Acid Filler

Calcium hydroxylapatite filler is a popular dermal filler, as it provides long-lasting results. However, it sometimes undergoes unexpected early volume loss, due to rapid gel absorption before neocollagenesis. To compensate for this phenomenon, hyaluronic acid filler was added to calcium hydroxylapatite filler for injection as a mixture. Twenty-five patients who scored 1 or 2 on the Merz 5-point scale for the nasolabial fold and jawline were injected with 3.0 mL of the mixture. The mixture was prepared with 1.0 mL of hyaluronic acid filler, 0.5 mL of lidocaine, and 1.5 mL of calcium hydroxylapatite filler. A visual analog scale (VAS) and the 5-point global satisfaction scale (GSS) were used for objective and subjective assessments. In a subset of patients, for histologic analysis, 0.1 mL of the mixture and 0.1 mL of only calcium hydroxylapatite filler were injected into the right and left postauricular areas, respectively. The histologic analysis was performed 6 months after implantation. The mean VAS and GSS scores for both sets of wrinkles were above "fair" at every follow-up, including at short-term and long-term periods. The skin biopsies from both postauricular areas from selected patients showed increased dermal collagen bundles without inflammation. The mixture of calcium hydroxylapatite filler and hyaluronic acid filler maintained constant volume with high satisfaction, as hyaluronic acid filler compensated for the unexpected early volume loss of calcium hydroxylapatite filler. This procedure can be applied safely, and it is also convenient, because no retouching procedure is needed.

Calcium hydroxylapatite: A review on safety and complications

BACKGROUND

Radiesse^® , or calcium hydroxylapatite (CaHA), is a biodegradable, biostimulatory soft tissue filler suitable for deeper folds and wrinkles. In the literature, good results have been documented with the use of CaHA and patient satisfaction scores are high. This study reviews the current literature on safety and complications of CaHA.

METHODS

A literature search in MEDLINE/PubMed electronic database was conducted. A total of 21 articles were included and screened for reports of adverse events (AEs).

RESULTS

Twenty-one peer-reviewed articles, published between 2004 and 2015, were included. A total of 5081 treatments with CaHA were performed on 2779 patients. A total of 173 (3%) AEs were reported. The assessed types of AEs consisted of nodules (n=166, 96%), persistent inflammation/swelling (n=4, 2%), persistent erythema (n=2, 1%), and overcorrection (n=1, 1%).

CONCLUSION

Based on the results in this study, CaHA appears to have a good safety profile. Nodules are by far the most common AE. Of the reported nodules, 49% occurred in "dynamic" areas currently known for having a higher tendency for nodules. Several treatment approaches exist for managing CaHA nodules; however, in most cases, CaHA nodules are not visible and resolve without intervention.

Shaping Lips with Fillers

The lips and the eyes enhance facial beauty, and they have been highlighted since time immemorial. Rejuvenating the lips with fillers, frequently hyaluronic acid (HA), is a common procedure but requires expertise. The objective of this text is to describe the procedure in detail and cover the practical aspects of injecting lips with fillers. An analysis of treating lips with needles and cannulae has been made with special emphasis on achieving optimum results.

Calcium hydroxylapatite for jawline rejuvenation: consensus recommendations

BACKGROUND

Age-associated volume loss is now known to play an important role in the structural changes of the aging face. In the lower face, this manifests as drooping of the corners of the mouth and jowl leading to a loss of the oval jawline of youth. Jawline reshaping by replacing volume has therefore become an indispensable component of modern facial rejuvenation.

AIM

Calcium hydroxylapatite (CaHA; Radiesse® , Merz Pharmaceuticals GmbH, Frankfurt, Germany) is an injectable filler with a cosmetic indication for tissue augmentation. The ability of calcium hydroxylapatite to provide immediate and long-lasting volume enhancement makes it an ideal agent for restoring an oval jawline.

METHOD

This consensus statement has been developed to assist clinicians who would like to gain more experience in the use of volumizing agents to achieve an optimal outcome with this procedure.

RESULTS

Using the recently developed Merz Aesthetics Scale® for jawline, the consensus provides a treatment protocol for individuals at each stage of oval loss and presents a series of before and after images to illustrate the improvements that can be achieved. Specific recommendations for calcium hydroxylapatite including type of anesthesia, injection techniques, volume for injection, use in combination with other procedures, and expected duration of corrections are provided. Techniques for minimizing and managing expected problems and potential complications are also described.

CONCLUSION

Calcium hydroxylapatite is appropriate for treating patients at any stage of oval loss.

Clinical data on injectable tissue fillers: a review

Treatment with injectable tissue fillers for aesthetic purposes is increasingly popular. In parallel with this success, questions related to the safety of these treatments and the products involved are being raised more prominently. To gain insight in the safety aspects of injectable tissue fillers, we performed a literature review to collect studies reporting clinical data of injectable tissue fillers. We found several case reports where serious complications after more than three years are described. However, there are only a limited number of well-defined prospective clinical studies available with follow-up periods longer than three years. Furthermore, causes of complications, that is, treatment or product related, are often not specified in literature. Considering the intended functional period of fillers in combination with the known occurrence of long-term complications, there is a need for well-defined prospective clinical studies. In order to be able to discriminate between product failure (a product safety issue) or application methodology (a physician expertise or training issue), better identification of observed complications and whether they are product or treatment related, is needed. For the safe use of the fillers it is important that treatment with injectable tissue fillers is performed by a trained physician, who knows the product specifications and its applications.

A novel solution for superficially placed calcium hydroxylapatite (Radiesse) in the inferior eyelid

Injectable fillers such as calcium hydroxylapatite (Radiesse) have become increasingly prevalent given their availability as an office procedure as well as their satisfying results. Calcium hydroxylapatite is well suited for use along bony structures in the face such as the inferior orbital rim and zygoma. On the other hand, it is not well suited for injection into the soft periorbital tissues and eyelid. In this case series we describe two cases of misplaced calcium hydroxylapatite in the inferior periorbita and eyelid; with a successful and relatively quick resolution of the complication using saline injections and erbium laser treatments.

Etiology, prevention, and treatment of dermal filler complications

The availability of dermal fillers for multiple cosmetic indications has led to a dramatic increase in their application. Although fillers are generally regarded as safe tools for soft tissue augmentation, complications can occur. Therefore, to describe and review the complications associated with the currently-available dermal filling agents, the authors conducted a literature review in peer-reviewed journals and present the reported complication rates. They also describe current strategies to avoid, diagnose, and manage complications if they do occur.

An evaluation of calcium hydroxylapatite (Radiesse) for cosmetic nasolabial fold correction: a meta-analysis and patient centric outcomes study

The use of calcium hydroxylapatite (Radiesse, BioForm Medical, San Mateo, California) for cosmetic soft tissue augmentation has increased significantly in recent years. Only a handful of authors have reported patient satisfaction data. A meta-analysis of published data was performed using a 5-point scale for patient satisfaction to allow data comparison across studies. A patient-centric outcomes study was also performed at our institution, using a blinded questionnaire. Five usable studies were identified for meta-analysis. Patient satisfaction was 4.16 of 5 in 324 patients at 3 to 6 months and 4.15 in 86 patients at 1 year. In our institutional patient-centric outcomes study, the early satisfaction rate was 3.7 of 5. At 1 year the rate was only 2.3 of 5. Calcium hydroxylapatite remains a viable option for augmentation of facial soft tissue structures. However, this report shows that further, accurate, large population outcomes assessments are absolutely required.

A five-patient satisfaction pilot study of calcium hydroxylapatite injection for treatment of aging hands

BACKGROUND

The process of skin aging is not limited to the face but involves every part of the body, including the hands. A common manifestation of aging of the hands is the loss of volume, which occurs as the skin loses its subcutaneous fat. Injectable dermal fillers have surfaced as a popular method to address such deficiencies.

OBJECTIVES

To report the use of calcium hydroxylapatite (CaHA) to address lost volume.

METHODS

Five female subjects with soft tissue deficiency of the dorsa of the hands were enrolled at Mount Sinai Medical Center. A solution of CaHA with 2% lidocaine in amounts of 0.3 to 1.0 mL was injected interdigitally at each of three to five insertion sites; the sites were massaged and molded up to three times to ensure an optimal cosmetic end point. Subjects were seen for a follow-up visit after 1, 4, 16, and 24 weeks.

RESULTS

With a single injection, all subjects reached their correction goals without requiring any touch-ups. At the 24-week visit, the subjects retained the filling effect, with no adverse events and high patient satisfaction.

CONCLUSION

CaHA, a new, easily injectable, safe dermal filler, has emerged as an excellent option for soft tissue augmentation in aging hands.

The lip: a histologic and analytical approach of relevance to esthetic plastic surgery

This is a study done for the first time to understand the histologic features of the lip deeply, quantitatively, and analytically and identify the differences between the outer, intermediate, and inner parts of the lips. Previous researchers did not tackle the histologic features of the lip from this point of view. Half lip was obtained from different well-preserved cadavers where the upper lip, lower lip, and lip angle were evaluated by coronal histologic sections. A total of 43 slides were studied and photographed using light and digital microscopes (Nikon COOLSCOPE, Nikon Corporation, Tokyo, Japan), respectively. The cadavers (26 men and 17 women) were in the age group of 45 to 65 years old, and older than 65 years. Data were entered on a study pro forma and statistically analyzed. Normal histologic features of the upper lip, intermediate, and the inner lip sections were observed. Fibrous septations that sometimes had muscular components inserting into them could be identified. In between these septations, there were loose areas (chambers). The mean numbers of chambers identified in the upper and lower lips were higher in the red areas, and more septations and chambers were identified in the lower lip. New histologic observations were classified into types 1 to 7. Significant relations were identified between the total number of septations and chambers in relation to age group and sex. Higher means of septations and chambers were detected in the age group older than 65 years, and in women as a whole. In conclusion, the findings detected in this work could explain the congenital lip pits that are familial or syndromic and many post-lip augmentation complications.

Advances in minimally invasive facial rejuvenation

PURPOSE OF REVIEW

Current cosmetic surgical practice for facial rejuvenation has undergone a significant change due to the introduction of technologies to improve the age-associated changes of the face. The most widely adopted methods of minimally invasive facial rejuvenation include the use of neuromuscular blocking agents and injectable fillers. The topic of minimally invasive procedures might include a variety of subjects including nutritional and hormonal modulation, light-based and laser-based therapies, minimal incision surgical procedures, as well as the use of botulinum toxin and fillers. The focus of this study will be on the minimally invasive facial rejuvenation efforts achieved by injection techniques.

RECENT FINDINGS

Botulinum A neurotoxin has been shown to be effective in the reduction of hyperfunctional lines in the upper and lower face. Anatomic areas that have been found to benefit include the glabella, the forehead, the periorbital area, lips, and the platysma muscle. The more recently introduced hyaluronic acid and other injectable fillers are receiving increasing usage. These temporary fillers have been found to improve creases and wrinkles, augment deep nasolabial folds, augment thin lips, and improve hollowing in the periorbital and other depressions and deformities.

SUMMARY

There has been a significant paradigm shift in the field of rejuvenation surgery. Injectable minimally invasive methods have been offered to remedy age-related and other acquired deformities of the head and neck region. These methods have provided temporary correction of undesirable characteristic that were traditionally approached with more invasive surgically oriented modalities.

Understanding, avoiding, and managing dermal filler complications

BACKGROUND Dermal fillers are increasingly being utilized for multiple cosmetic dermatology indications. The appeal of these products can be partly attributed to their strong safety profiles. Nevertheless, complications can sometimes occur. OBJECTIVE To summarize the complications associated with each available dermal filling agent, strategies to avoid them, and management options if they do arise. METHODS AND MATERIALS Complications with dermal fillers reported in peer-reviewed publications, prescribing information, and recent presentations at professional meetings were reviewed. Recommendations for avoiding and managing complications are provided, based on the literature review and the author's experience. RESULTS Inappropriate placement or superficial placement is one of the most frequent reasons for patient dissatisfaction. Due to the reversibility of hyaluronic acid, complications from these fillers can be easily corrected. Sensitivity to any of the currently approved FDA products is quite rare and can usually be managed with anti-inflammatory agents. Infection is quite uncommon as well and can usually be managed with either antibiotics or antivirals depending on the clinical features. The most concerning complication is cutaneous necrosis, and a protocol to treat the full spectrum of this process is reviewed. CONCLUSIONS Complications with dermal fillers are infrequent, and strategies to minimize their incidence and impact are easily deployed. Familiarity with each family of soft-tissue augmentation products, potential complications, and their management will optimize the use of these agents.

Use of calcium hydroxylapatite (Radiesse) for facial augmentation

Radiesse^® (Bioform Inc, USA) is a sterile, latex-free, non-pyrogenic, semi-solid, cohesive subdermal, injectable implant, whose principal component is synthetic calcium hydroxylapatite, a biocompatible material with over 20 years of use in medicine. The semi-solid nature of the product is created by suspending calcium hydroxylapatite microspheres of 25–45 microns diameter in a gel carrier of carboxymethylcellulose. The product has FDA approval for esthetic facial augmentation in the US. Such approval includes the long-lasting correction of moderate to severe facial wrinkles and folds and the treatment of facial fat loss due to immunodeficiency virus infection. Diverse facial regions can be injected in order to ameliorate or enhance some features: glabellar lines, subdermal support of the brows, malar and buccal fat pads, tear troughs, nasolabial folds, nose, lips, perioral region, marionette lines, oral commisures and chin among others, as well as saucerized acne scars. Other medical indications include nipple projection for nipple areolar reconstruction, urinary incontinence, vesicoureteral reflux, vocal cord augmentation, and use as a radiographic tissue marker. The average lasting result is from 12 to 18 months. Radiesse can be considered an effective soft-tissue filler for overall longevity, biocompatibility, and low rate of side effects.

Lip augmentation with porcine small intestinal submucosa

OBJECTIVE

To relate our initial experience using an acellular, soft tissue matrix derived from porcine small intestinal submucosa (Surgisis; Cook Biotech Inc, West Lafayette, Indiana) for lip augmentation.

DESIGN

A prospective, uncontrolled case series examining the results of lip augmentation using Surgisis in patients presenting to an academic otolaryngology/facial plastic surgery office.

RESULTS

Nineteen Surgisis implants were placed in 8 patients. All patients tolerated the procedure and denied unnatural sensations or complications at any interval. Adverse events included transient erythema and 1 case of local cellulitis treated effectively with oral antibiotics. Four patients were satisfied with the procedure and 4 patients requested greater augmentation. Six-month follow-up was reported, and preoperative and postoperative photography was used in all cases.

CONCLUSIONS

Short-term lip augmentation was achieved in all 8 patients (4 patients had multiple strands placed). This study demonstrates technical ease and early safety. Surgisis should serve as scaffolding for ingrowth of striated muscle of the lip, potentially providing long-term augmentation. This study introduces Surgisis as a novel implant for lip augmentation.

Foreign body reaction to calcium hydroxylapatite after lip augmentation

BACKGROUND

Dentists need to be aware of soft-tissue lesions resulting from cosmetic facial/lip procedures that involve the use of injectable materials. Common side effects detected on clinical examination may include edema, bruising and noninflammatory lip nodules.

CASE DESCRIPTION

A 51-year-old woman visited a dental clinic with the chief complaint of a lump on the mucosal aspect of her lower lip. She reported having noted the lesion a few weeks before seeking care at the clinic. Several weeks later, the lesion persisted and new lesions were detected. The clinician excised the initial lesion only.

CLINICAL IMPLICATIONS

The lip nodules were associated with a cosmetic procedure and were inflammatory in nature. This is the first granulomatous response reported as a result of injections with calcium hydroxylapatite (Radiesse, BioForm Medical, San Mateo, Calif.). Poor patient recollection of his or her medical history may result in confusion with pathological processes such as infection, neoplasia or malignancy.

Calcium Hydroxylapatite: Radiesse

Among the array of choices for aesthetic soft tissue fillers, Radiesse occupies a unique niche as a safe, easily administered, "semi-permanent" material. Composed of calcium hydroxylapatite in a gel matrix, it has a proven safety profile and has been approved by the US Food and Drug Administration for use in the nasolabial folds and for HIV lipoatrophy. Radiesse have evolved quickly into a effective filler for moderately deep facial folds with high patient and physician approval.

Calcium Hydroxylapatite Facial Filler (Radiesse™): Indications, Technique, and Results

This article discusses the use of Radiesse; a semisolid, cohesive subdermal injectable implant. Through direct and invaluable experience gained over time, plastic surgeons will decide which areas of the face may best be suited for Radiesse and which may be appropriate for other fillers.
