RESUMO

Integrated skin care is defined as the complementary use of topical treatments to nonsurgical facial rejuvenation procedures, such as lasers and radiofrequency microneedling devices, to produce pleasing aesthetic results. Real-world experience from expert dermatologists is invaluable in guiding patient treatment plans, as there are limited clinical trials on the efficacy of integrated skincare regimens. The SkinCeuticals (New York, NY) Phyto Corrective gel (botanical serum-containing corrective gel) contains a lightweight botanical serum that hydrates, calms, and soothes skin. It contains antioxidant and anti-inflammatory ingredients derived from plant and fruit extracts, making it an appealing option for adjunctive treatment of post-procedure erythema and swelling.  J Drugs Dermatol. 2024;23:3(Suppl 2):s3-s14.

RESUMO

BACKGROUND: Rosacea is a chronic inflammatory skin condition of varying severity that can significantly impact patient quality of life. Intense pulsed light (IPL) is an established treatment for rosacea-associated telangiectasia, inflammation, and erythema. This study assessed whether application of a phyto-corrective mask, gel, and resveratrol antioxidant serum after IPL treatment can improve outcomes and reduce procedure-related adverse effects. METHODS: In a prospective, open-label, split-face, 3-month study, 10 subjects with moderate-to-severe facial rosacea underwent IPL treatment on both sides of the face. The following were applied to the right side of the face only: phyto-corrective mask once weekly starting immediately after IPL; phyto-corrective gel twice daily; and resveratrol antioxidant treatment at night. Both sides of the face were treated with sunscreen. Subjects were assessed on Day 1, 1 and 3 months after IPL by three, independent evaluators using the 5-point Global Aesthetic Improvement Scale (GAIS). All subjects rated skin redness, hydration, and overall improvement on Day 1 and completed a patient satisfaction questionnaire at the 1- and 3-month visits. RESULTS: Ten women were enrolled, aged 44-72 years old, with moderate (n = 6) to severe (n = 4) rosacea. IPL was effective at reducing symptoms with rosacea classified as absent in five women and mild in five at the final 3-month visit. GAIS scores also revealed improvements on both sides of the face, but the skincare treated side showed continuous improvement over 3 months with all patients remaining at least "Improved", whereas there appeared to be a waning effect after 1 month with IPL alone. On Day 1 after IPL, all women reported less redness, improved hydration, and improved skin appearance on the right side of the face. Patient satisfaction was consistently rated higher on the right side of the face. CONCLUSION: Application of a phyto-corrective mask, gel, and resveratrol antioxidant serum may complement IPL treatment for rosacea by enhancing treatment outcomes and reducing procedure-related symptoms.

RESUMO

BACKGROUND: Chronic exposure of the skin to environmental factors, including solar radiation and air pollution, promotes skin aging by inducing inflammation which damages the skin. Heparan sulfate (HS) is one of the glycosaminoglycans, which has a central role in modulating skin repair. In its appearance in the skin, HS is large and highly polar and therefore unable to penetrate the skin. As a component in a topical formulation, the modified to a low molecular weight heparan sulfate analog (LMW-HS) showed biological modulation activity. AIMS: This review discusses the potential role of topical formulations containing LMW-HS in restoring aged-skin homeostasis and skin health. METHODS: An expert panel of dermatologists who regularly treat clinical signs of facial photoaging explored the role of LMW-HS containing formulations for reducing inflammation and facial-aging signs. For this purpose, evidence from the conducted literature searches was used together with expert opinion and experience of the panel. RESULTS: Extrinsic factors contribute to skin aging through oxidative stress, stimulating inflammation involved in extracellular matrix degradation. Evidence showed that chemokines require heparan sulfate for their full range of functional activities during innate immunity. Studies showed the LMW-HS containing topical formulation to penetrate the skin within 48 hours of once-daily application. LMW-HS used in the periorbital area improved discoloration and wrinkles at Week 2 with continuous improvement up to Week 12. CONCLUSION: The LMW-HS containing formulation showed improvements in skin condition when applied on photo-damaged skin, indicating its therapeutic potential.

RESUMO

BACKGROUND AND OBJECTIVES: There is a wide diversity of opinions regarding the management of delayed inflammatory reactions (DIRs) secondary to hyaluronic acid (HA)-based fillers. The plethora of approaches has led the authors to conduct a review regarding management and treatment of DIRs as well as establish therapeutic guidelines for this purpose. MATERIALS AND METHODS: A review of the literature was performed through databases such as PubMed using keywords including HA-fillers and complications, delayed HA filler sequelae and therapy, soft tissue and dermal filler reactions and management. Additionally, a survey comprised of questions regarding the management and treatment of DIRs was sent to 18 physicians highly experienced with soft-tissue filler injections in 10 countries. Their answers and recommendations were analyzed and debated amongst these panelists. RESULTS: Sixteen panelists favored antibiotic therapy as first-line treatment for DIRs, specifically dual antibiotic therapy consisting of a fluoroquinolone along with a tetracycline or macrolide for a period of 3-6 weeks. The majority refrained from the use of intralesional (IL) or systemic steroids except in the case of disfiguring or recalcitrant reactions. IL hyaluronidase was recommended by 13 panelists; however, some preferred a watchful waiting approach for a period of 48 hours to 2 weeks prior to IL hyaluronidase, and in cases where antibiotics did not lead to improvement. CONCLUSION: A consensus was reached and summarized to propose a clear, easy-to-follow, stepwise algorithm for the treatment of DIRs.

RESUMO

Introduction: Acne vulgaris is a highly prevalent skin condition that can adversely affect the quality of life. Acne-predisposed skin is in a state of subclinical inflammation leading to skin barrier dysfunction. A multi-center cohort study was designed to evaluate clinical efficacy and safety of twice daily facial cleansing using an oscillatory sonic brush, acne brush head, and cleansing gel for 4 weeks. Methods: Subjects with mild-to-moderate acne and acne-prone skin used the cleansing regime after which they applied the skin care products they routinely used. Physician-assessed skin condition comparing baseline versus week 4 using the FDA/IGA scale and subject satisfaction with cleansing efficacy and handling properties of the regime were scored during the last visit. Results: Forty-six subjects completed the study. Physician-scored skin condition showed a statistically significant improvement in FDA/IGA scores and a significant reduction of inflammatory and non-inflammatory lesions comparing baseline versus 4 weeks. Thirty-five (76.0%) subjects had cleared or almost cleared. Subjects similarly assessed their skin to be improved. Conclusion: Both the physician and subject scores revealed the gentle cleansing routine using the sonic brush to be effective reducing the number of acne lesions, improving skin condition. No adverse events were reported during the study period. The cleansing regime may offer an attractive, safe option for maintenance and treatment of subjects with mild-to-moderate acne and acne-prone skin. J Drugs Dermatol. 2019;18(11):1140-1145.

RESUMO

Background: Among the growing aesthetic patient population, Hispanic/Latinos represent the largest proportion of non-Caucasians patients. While treatment of Caucasian facial aging patterns are well documented, far less information describes the aesthetic needs of the Hispanic/Latino patient. Objective: An online study was designed to survey facial aesthetic concerns, treatment priorities, and future treatment considerations among a US-based population of Hispanic/Latino American women. Materials and Methods: A total of 401 participants ages 30 to 65 years reported their attitudes toward facial aging, current facial conditions, most bothersome facial areas, areas most/least likely to be treated first, awareness of treatment options and their consideration rates, and motives and barriers that factor into consideration of injectable treatments. Results: Most participants wanted to look good for their age and treatment interests reflected predominant conditions: facial wrinkles, periorbital signs of aging, and uneven skin tone. Most bothersome facial areas included the submental area, periorbital area, and forehead, which were also among the areas most-likely to treat first. The majority of participants would consider injectables. Cost and safety/side effects were cited as frequent concerns. Conclusion: An understanding of the facial aesthetic concerns and treatment priorities specific to Hispanic/Latino women will enhance the practitioner's patient-centric treatment approach.

RESUMO

Background: The gold standard for the treatment of hyperpigmentation is hydroquinone (HQ), which has been available as a skin lightener for more than 50 years. Numerous clinical studies have proven its efficacy in various topical formulations. In the United States, HQ is available as a nonprescription product in 2% formulations and as a 4% prescription product. Objective: This study compared the safety and efficacy of a 2% hydroquinone multi-ingredient foam with a standard 4% hydroquinone cream on photodamaged facial skin. Methods: A 12-week, investigator-blinded, randomized trial with a split-face design was conducted in women with moderate photodamaged facial skin. Results: Both products improved the appearance of photodamaged facial skin and were well-tolerated. No statistically significant changes were seen between treatments during the efficacy or tolerability evaluations. Conclusion: Both treatments (2% HQ Brighten and 4% HQ) improved the appearance of photodamaged facial skin and were well-tolerated and results well-perceived by subjects over the 12-week treatment period, compared with baseline grading scores.

RESUMO

BACKGROUND/OBJECTIVES: Anti-aging strategies utilizing stem cells are in the forefront. Alpha and beta defensins are natural immune peptides that have been shown to activate an LGR6-positive stem cell locus in the hair follicle, identified as the source of most new epidermal cells during acute wound healing. We investigated the ability of biomimetic alpha and beta defensin molecules, supplemented with supportive cosmetic ingredients, formulated into three skin care products, at improving the structure and function of aging skin. METHODS: A participant- and investigator -blinded, placebo-controlled, multi-center trial was performed in outpatient settings. Forty-four healthy female subjects, aged 41-71 years, skin types I-V, completed the study with 2/3 receiving full formula and 1/3 receiving the placebo formula. A skin care regimen of 3 products (serum, cream, and mask) containing alpha-defensin 5 and beta-defensin 3, and other cosmetic ingredients, was applied to the face, post-auricular, and neck skin two times per day for 12 weeks in those receiving full formula, whereas the placebo group received the identically packaged regimen without the active ingredients. Methods of evaluation included histopathology and immunohistochemistry (7 subjects), clinical evaluation of pores, superficial and deep wrinkles based on Griffiths scale, and high-resolution photography (all subjects). In addition, a subset of 15 patients were evaluated with the QuantifiCare system (3-dimensional imaging and skin care scores for evenness, pores, oiliness) and Cortex measurements (high-resolution skin ultrasound, TEWL, elasticity, color, and hydration). Data points for evaluation included baseline, 6 weeks, and 12 weeks. All patients used the same sunscreen and cleanser, which was provided to them. RESULTS: The full formula regimen caused a significantly (P equals 0.027) increased thickness of the epidermis as seen in histology, not seen in the placebo group, with no signs of inflammation. No excessive cell proliferation was detected in either group as measured by Ki67-immunohistochemistry. Reduction in visible pores, superficial wrinkles, oiliness, pigmentation, and improvement of skin evenness, were statistically significant. A trend for improvement was also observed in skin elasticity, TEWL, and hydration; these did not achieve statistical significance. Ultrasound and histopathology demonstrated increases in dermal thickness in individual patients, without statistical significance. Comprehensive improvement in all 5 parameters, including visible pores, hyperpigmentation, superficial and deep wrinkles, and epidermal thickness, was statistically significant when the subset of participants assigned for histology in full formula group was compared with the placebo group participants. CONCLUSIONS: A 3-product skin care regimen containing alpha and beta defensins globally improves the visual appearance and structure of aging skin without irritation, dryness, or inflammation. Specifically, this regimen increases epidermal thickness, reduces appearance of pores, reduces wrinkles, and reduces melanin. This skin care regimen stimulates rejuvenation without evidence of increase of a marker of carcinogenic stimulation. This data is consistent with the hypothesis that a defensin-containing skin care regimen activates the body's own dormant stem cells to generate healthy new epidermal cells.

RESUMO

Normal aging and photoaging of the skin are chronic processes that progress gradually. The extracellular matrix (ECM), constituting over 70% of the skin, is the central hub for repair and regeneration of the skin. As such, the ECM is the area where changes related to photodamage are most evident. Degradation of the ECM with fragmentation of proteins significantly affects cross talk and signaling between cells, the matrix, and its constituents. The accumulation of collagen fragments, amorphous elastin agglutinations, and abnormal cross-linkages between the collagen fragments impedes the ECM from its normal repair and regenerative capacity, which manifests as wrinkled, non-elastic skin. Similar to how the chronic wound healing process requires wound bed preparation before therapeutic intervention, treatment of chronic aging of the skin would likely benefit from a "skin bed preparation" to optimize the outcome of rejuvenation procedures and skin maintenance programs. This involves introducing agents that can combat stress-induced oxidation, proteasome dysfunction, and non-enzymatic cross linkages involved in glycation end products, to collectively modulate this damaged ECM, and upregulate neocollagenesis and elastin production. Agents of particular interest are matrikines, peptides originating from the fragmentation of matrix proteins that exhibit a wide range of biological activities. Peptides of this type (tripeptide and hexapeptide) are incorporated in ALASTIN™ Skin Nectar with TriHex™ technology (ALASTIN Skincare, Inc., Carlsbad, CA), which is designed to target ECM modulation with a goal of optimizing results following invasive and non-invasive dermal rejuvenating procedures.

RESUMO

Skin aging is a combination of multifactorial mechanisms that are not fully understood. Intrinsic and extrinsic factors modulate skin aging, activating distinctive processes that share similar molecular pathways. One of the main characteristics of youthful skin is its large capacity to retain water, and this decreases significantly as we age. A key molecule involved in maintaining skin hydration is hyaluronic acid (HA). Concentration of HA in the skin is determined by the complex balance between its synthesis, deposition, association with cellular structures, and degradation. HA bio-equivalency and bio-compatibility have been fundamental in keeping this macromolecule as the favorite of the skincare industry for decades. Scientific evidence now shows that topically applied HA is unable to penetrate the skin and is rapidly degraded on the skin surface. SkinMedica's HA5 Rejuvenating Hydrator (SkinMedica Inc., an Allergan company, Irvine, CA) promotes restoration of endogenous epidermal HA homeostasis and provides instant smoothing and hydration of the skin. These dual benefits are accomplished through the combination of 2 breakthrough technologies: 1) a unique blend of actives powered by SkinMedica proprietary flower-derived stem cell extract that restores the endogenous production of HA; and 2) a proprietary mix of 5 HA forms that plump the skin, decreasing the appearance of fine lines/wrinkles. Pre-clinical studies demonstrated that HA5 induces expression of key epidermal differentiation and barrier markers as well as epidermal HA synthases. A decrease expression of hyaluronidases was also observed upon HA5 application. Initial clinical studies showed that within 15 minutes of application, HA5 instantly improves the appearance of fine lines/wrinkles and skin hydration. Subjects that continue using HA5 (for 8 weeks) demonstrated significant improvements in fine lines/wrinkles, tactile roughness, and skin hydration. In summary, the blend of these 2 key technologies present in HA5 promotes restoration of endogenous epidermal HA while delivering instant smoothing effects.

RESUMO

BACKGROUND: Cosmetic physicians are more and more frequently asked for hand rejuvenation. They commonly propose the same techniques as for the face. The authors undertook an anatomical study of the hand dorsum to understand the optimal location for an injected filler and to design the safest technique of placement. METHODS: The first part of the study included dissections of 19 fresh cadaveric hands and duplex ultrasounds investigation of 28 healthy hands. A technique of injection specifically designed from anatomical findings was then tested on 8 fresh cadaveric hands using magnetic resonance imaging and dissection in comparison with 3 other commonly used techniques of rejuvenating injections. RESULTS: Between the dermis and the tendons, the thickness of the fascial plane was measured from 0.3 to 2.2 mm. Because of numerous fibrous septa, the entire plane was found as a 3-dimensional sponge-like framework. Veins could be located in all levels of this framework. There was no predefined free space. The optimal place for the deposition of a filler was found to be the undersurface of the dermis. The specific technique named Scrape Skin Threading Technique and using a cannula scraping the deep side of the dermis was checked as the only technique which could give a perfect placement of product restricted to the fascial layer. CONCLUSION: The Scrape Skin Threading Technique was designed to inject safely and accurately any kind of injectable in contact with the undersurface of the dermis, which appeared anatomically as the optimal location of a filler for enhancing the outer appearance of the dorsum of hands.

RESUMO

Alopecia and thinning hair are highly prevalent conditions affecting a large proportion of men and women. Diffused hair loss is often more difficult to diagnose in women, mostly due to over-reliance on the assumption of hormonal influences, and it is commonly treated with a multi-therapy approach. Clinical studies have demonstrated the effectiveness of a nutraceutical supplement to provide essential nutrients that aid in stimulating existing hair growth and reducing hair shedding. The supplement Viviscal® contains a proprietary blend of proteins, lipids, and glycosaminoglycans derived from sustainable marine sources. We present here a summary of studies that have examined the safety and efficacy of this nutraceutical; as well as discussions on hair loss and current therapies from a recently convened expert panel in dermatology and plastic surgery.

RESUMO

Heparan sulfate is an essential glycosaminoglycan that plays important roles in development, homeostasis, and disease. As a group, the glycosaminoglycans provide mechanical strength to skin, as they can absorb water and occupy the space between elastin fibers and collagen. Heparan sulfate is also a key participant in cell proliferation, cell migration, collagen fiber formation, basement membrane regeneration, granulation tissue formation, and cell adhesion associated with wound healing. A variety of dermatological disorders are associated with changes in glycosaminoglycans or their associated proteoglycans. A new topical formulation of low molecular weight heparan sulfate glycosaminoglycan has been shown to penetrate the epidermis, basement membrane, and dermis within 24 hours of application. In an 8-week study, 15 patients using this new formulation showed improvement in skin hydration, skin firmness, skin elasticity, skin barrier function, and global fine lines and wrinkles. Incorporating low molecular weight heparan sulfate into topically applied formulations may represent a new approach to improving the appearance of photodamaged skin.

RESUMO

For more than a century, solar radiation has been known to contribute significantly to the extrinsic aging of skin. Until recently, this was almost exclusively attributed to the photodamage caused by ultraviolet (UV) light. However, a growing body of evidence now indicates that both infrared (IR) and visible light may also contribute to extrinsic skin aging. Infrared radiation, comprised of IR-A, IR-B, and IR-C, accounts for 54.3% of the total solar radiation reaching the skin. Studies have shown that IR radiation is also responsible for skin aging. Thus, IR-A radiation regulates hundreds of genes in skin, with roles in extracellular matrix (ECM) homeostasis regulation, apoptosis, cell growth, and stress responses. IR-B and IR-C radiation are primarily responsible for the increase in skin temperature associated with solar exposure, and are implicated in heat-related skin destruction of collagen and elastin, which is characterized by an increase in the expression of matrix metalloproteinases (MMPs). The contribution of visible light to photoaging is less well understood; however, some preliminary indication associates visible light with the upregulation of MMPs' expression, DNA damage, and keratinocyte proliferation. Interestingly, the common denominator that links skin damage to the different solar wavelengths is the enhanced production of reactive molecule species (RMS) and therewith increased oxidative stress. SkinMedica® Total Defense + Repair (TD+R; SkinMedica Inc., an Allergan company, Irvine, CA) is a "superscreen," which combines broad spectrum UV protection with a unique blend of antioxidants (SOL-IR Advanced Antioxidant Complex™) that provide protection from IR radiation while promoting skin repair. Preclinical studies have indicated that TD+R SPF34 prevents the formation of UV-induced sunburn cells and cyclobutane pyrimidine dimers while preserving or improving the expression of ECM genes. In addition, it prevents IR-A-triggered fragmentation of elastin fibers and expression of MMP-1. Initial clinical studies indicate that TDR+R SPF34 reduces the increase in surface temperature seen with IR radiation. A significant improvement in the appearance of lines and wrinkles was reported as early as week 2 in patients using TDR+R SPF34. In summary, we observed that the unique blend of antioxidants present in TD+R acts in harmony with SPF active ingredients, expanding solar protection beyond UV radiation and counterbalancing the deleterious effects of free radicals on skin cells by promoting endogenous repair.

RESUMO

INTRODUCTION: Extracts of the tropical fern Polypodium leucotomos appear to possess beneficial properties for the skin attributed to the presence of numerous compounds within the extract that have antioxidant and photoprotective properties. Orally administered Polypodium leucotomos may provide protection against the detrimental photoaging effects of sunlight and can also help reduce the frequency and severity of polymorphous light eruption. Polypodium leucotomos has also been shown to be beneficial for the prevention and potential treatment of several aesthetically relevant conditions. OBJECTIVE: The purpose of this review is to investigate the beneficial role of Polypodium leucotomos as an adjunct treatment for vitiligo, melasma, and postinflammatory hyperpigmentation. RESULTS: Based on a review of relevant literature including the results of a randomized, placebo-controlled study, the oral administration of Polypodium leucotomos significantly improved the severity of melasma in women after 12 weeks. Three randomized, double-blind, placebo-controlled studies have demonstrated significant improvements in vitiligo when oral Polypodium leucotomos therapy was combined with psoralens plus ultraviolet A and narrowband ultraviolet B. No controlled studies have assessed the efficacy of Polypodium leucotomos for the treatment of postinflammatory hyperpigmentation; however, its known antioxidant and anti-inflammatory properties and demonstrated effectiveness for melasma support its use for treating this condition. No adverse events have been associated with the use of Polypodium leucotomos. CONCLUSION: In addition to preventing many harmful effects associated with sunlight exposure, orally administered Polypodium leucotomos also appears to provide adjunctive benefits in treating vitiligo, melasma, and may have the potential to help with postinflammatory hyperpigmentation.

RESUMO

BACKGROUND: Photoaged skin is characterized by a variety of clinical, histologic, and biochemical features. OBJECTIVE: To determine the efficacy of a new topical formulation of 1% retinol and the effects of this same formulation using a 0.5% retinol concentration to minimize irritation. METHODS: Patients at 2 sites (n=6, n=5) with photodamaged skin applied a novel suspension of retinol (1%) daily to their faces for 8 to 12 weeks. Clinicians graded improvement in ultraviolet-induced features at 4 to 6 weeks and at 8 to 12 weeks. Positive results of the observational pilot study warranted a follow-up study on the low concentration. At a third site, females (n=30) with facial photodamage applied the same formulation with or without retinol (0.5%) daily for 8 weeks. Twenty-two subjects applied the test product and 8 applied vehicle according to a randomized, double-blinded, institutional review board-approved protocol. Improvements in photodamage features were graded at 4 and 8 weeks. RESULTS: In the observational pilot study, most participants showed improvement in overall photodamage, crow's feet, elasticity,wrinkles, brightness, and hyperpigmentation at 60 to 80 days. Improvements at 60 to 80 days were greater than at 30 to 46 days. In the low-concentration study with 0.5% retinol, improvements were modest, most likely due to the lower retinol concentration. Burning, pruritus, dryness, and erythema were minimal with the 0.5% retinol concentration. CONCLUSIONS: The topical formulation of 1% retinol improves photodamaged skin for at least 8 to 12 weeks. Although improvements with the 0.5% retinol were more modest, side effects such as burning, dryness, pruritus, and erythema during the 8-week study period were minimal. These encouraging results justify a longer-term study to determine whether topically applied 0.5% retinol can provide benefits comparable with those seen with topically applied 1% retinol.

RESUMO

Radiofrequency has been shown in a number of studies to be effective in tightening the skin of the face and neck. This multicenter study was undertaken to determine the efficacy of a monopolar radiofrequency system (Pellevé S5 Wrinkle Treatment Generator; Ellman International Inc, Oceanside, NY) in tightening the skin of the hands and is the first such study assessing the improvement of skin laxity of the hands. A total of 31 female patients with a median age of 56 years were enrolled in 2 centers. Each had a single hand treated, with randomization of the hand to be treated. A total of 3 treatments were performed at 2-week intervals. Follow-up photos were taken at 45 and 90 days after the final treatment. At 90 days, 89% of patients had visible improvement of the appearance of the treated hand based on the visual Global Aesthetic Improvement Scale. Of these, 50% had visible improvement from baseline, and 39% had marked improvement from baseline. Patients reported only mild to moderate discomfort during the treatment. No adverse events or side effects were reported. Monopolar radiofrequency was found to be safe and effective for treating hand wrinkles.

RESUMO

This article discusses adjunctive skin care of the brow and periorbital region. Anatomic properties of eyelid skin require skin care products specifically suited to this area. Common patient concerns, including wrinkles, infraorbital dark circles, puffiness, and thinning eyebrows and eyelashes, are addressed in the context of contributing anatomic and physiologic factors and the classes of and/or specific ingredients targeting these problems.

RESUMO

The amount and complexity of scientific and clinical evidence for aesthetic use of botulinum neurotoxin type A (BoNT-A) has expanded rapidly in recent years, especially for abobotulinumtoxinA, necessitating reassessment of current knowledge about aesthetic use of abobotulinumtoxinA and other BoNT-A preparations. A committee of 13 plastic surgeons, facial plastic surgeons, and dermatologists engaged in a live discussion of information from a systematic literature review and an Internet-based survey of their beliefs and practices. The committee achieved consensus on most issues. It was concluded that doses of different BoNT-A preparations cannot be interconverted with a fixed ratio. The size of the "field of effect" is difficult to measure, and comparisons between preparations have yielded equivocal results. Nonresponse due to neutralizing antibodies appears exceedingly rare with currently available BoNT-A preparations and of little concern clinically. BoNT-A dose, injection depth, and injection technique should be adjusted according to the anatomic area being treated and each patient's individual characteristics and goals. Aesthetic use of BoNT-A has a good safety profile. Most adverse events are minor and related to the trauma of injection, although special care is needed in certain anatomic areas. Detailed recommendations for treatment of different anatomic areas are presented. BoNT-A products are often used in conjunction with other treatment modalities (eg, fillers and resurfacing), but little agreement was reached on best practices. The findings reported in this consensus document may serve as a practical guide for aesthetic practitioners as they apply the latest knowledge about BoNT-A in providing their patients with optimal care.
