RESUMO

BACKGROUND: PrabotulinumtoxinA is a 900-kDa botulinum toxin type A produced by Clostridium botulinum. OBJECTIVES: The authors sought to investigate the safety of prabotulinumtoxinA for treatment of glabellar lines. METHODS: This was a multicenter, open-label, repeat-dose, 1-year phase II safety study. Adults with moderate to severe glabellar lines at maximum frown, as assessed by the investigator on the validated 4-point photonumeric Glabellar Line Scale (0 = no lines, 1 = mild, 2 = moderate, 3 = severe), were enrolled. On day 0, patients received an initial treatment of 20 U prabotulinumtoxinA (4 U/0.1 mL freeze-dried formulation injected into 5 target glabellar sites). On and after day 90, patients received a repeat treatment (RT) if their Glabellar Line Scale score was ≥2 at maximum frown by investigator assessment. Safety was evaluated throughout the study. RESULTS: The 352 study patients received a median total dose of 60 U, that is, 3 treatments per year. Fifty-one patients (14.5%) experienced adverse events (AEs) assessed as possibly study drug related; 11.1% experienced study drug-related AEs after the initial treatment. With each RT, progressively lower percentages of patients experienced study drug-related AEs. Six patients (1.7%) experienced study drug-related AEs of special interest: 3 eyelid ptosis (0.9%), 2 speech disorder (0.6%), and 1 blepharospasm (0.3%). Seven patients (2.0%) experienced serious AEs; none were study drug related. Of the 2393 samples tested, 2 patients (0.6%) tested positive for antibotulinum toxin antibodies at a single postbaseline visit. CONCLUSIONS: The safety of RTs of 20 U of prabotulinumtoxinA for moderate to severe glabellar lines was first established in this early phase II study based on a broad range of outcomes.

RESUMO

Since initial US Food and Drug Administration approval of botulinum toxin type A (BoNT-A) for aesthetic use in 2002, clinical evidence and experience with BoNT-A and understanding of facial anatomy have greatly increased, leading to rapid advances in treatment planning and implementation. BoNT-A use has expanded from the upper face to the midface, lower face, and neck, so that BoNT-A injection is the most common cosmetic procedure worldwide. Trends in facial aesthetics reflect growing patient diversity with respect to age, gender, and ethnicity. In October 2019, a multidisciplinary panel of 6 experts in minimally invasive injectable procedures in the specialties of dermatology and plastic surgery convened at the 2019 American Society for Dermatologic Surgery (ASDS) meeting in Chicago, IL. Their goal was to discuss recent advances in BoNT-A use in facial aesthetics, including implications of the introduction of new agents in light of an evolving patient population.

RESUMO

BACKGROUND: Approved topical treatments for seborrheic keratoses (SKs) are an unmet need. OBJECTIVE: To evaluate the safety and efficacy of 40% hydrogen peroxide topical solution (HP40) versus vehicle for the treatment of SKs (A-101-SEBK). METHODS: A total of 937 patients with 4 SKs each (≥1 lesion each on the face and on the trunk and/or an extremity) were randomized 1:1 to HP40 or vehicle. At each visit, SKs were graded using the Physician's Lesion Assessment (PLA) scale (0, clear; 1, nearly clear; 2, ≤1 mm thick; and 3, >1 mm thick). After 1 treatment, SKs with a PLA score higher than 0 were re-treated 3 weeks later. RESULTS: At day 106, significantly more patients treated with HP40 than with vehicle achieved a PLA score of 0 on all 4 SKs (study 1, 4% vs 0%; study 2, 8% vs 0% [both P < .01]) and on 3 of 4 SKs (study 1, 13% vs 0%; study 2, 23% vs 0% [both P < .0001]). A higher mean per-patient percentage of SKs were clear (study 1, 25% vs 2%; study 2, 34% vs 1%) and clear or nearly clear (study 1, 47% vs 10%; study 2, 54% vs 5%) with HP40 than with vehicle. Local skin reactions were largely mild and resolved by day 106. LIMITATIONS: The optimal number of treatment sessions was not evaluated. CONCLUSION: Application of HP40 was well tolerated and effective in the removal of SKs.

RESUMO

Skin aging is continuously influenced by various internal and external factors such as the biologic progression of cells, ultraviolet (UV) radiation, tobacco, nutritional deficiencies, and hormonal imbalances that lead to the degradation of skin cells. Through the degradation of skin cells, free radicals and inflammation weaken repair mechanisms and result in collagen and elastic fiber breakdown. The appearance of aging skin is highlighted by skin roughness, wrinkling, pigmentation change, telangiectasias, loss of elasticity, and decreased firmness, all of which are accelerated by these internal and external factors. Throughout the years, nutraceuticals have been studied to delay and fight against these internal and external factors, many of which are found in foods and byproducts consumed naturally. The aim of this review is to aid dermatologists in understanding the mechanism of action of popular nutraceuticals and their possible efficacy in antiaging and skin health.

RESUMO

BACKGROUND: With the baby boomer generation firmly ensconced in middle age and the ubiquity of botulinum toxin type A, nonsurgical facial rejuvenation is becoming increasingly prevalent. As this generation continues to age, products with greater therapeutic power to correct aging changes will be in growing demand. METHODS: A multicenter, double-blind, randomized, within-subject, controlled study was conducted comparing Juvéderm Ultra Plus hyaluronic acid filler with bovine collagen. A subset of subjects classified as having treatment for severe nasolabial folds is presented in this article. Subjects received Juvéderm Ultra Plus in one severe nasolabial fold and Zyplast collagen in the other nasolabial fold; up to two touch-up treatments were allowed at 2-week intervals. Nasolabial fold severity was evaluated every 4 weeks for 24 weeks using a five-point scale. Treatment site reactions and adverse events were also recorded. A complimentary treatment was offered at the end of the trial, with effectiveness evaluations just before retreatment and up to 48 weeks after repeated treatment for a subset of subjects. RESULTS: Of the 87 subjects, most were female Caucasians, but all Fitzpatrick skin types were represented (36 percent types IV through VI). At 24 weeks, 96 percent of nasolabial folds treated with Juvéderm had maintained clinically significant correction, and 81 percent maintained the correction for 1 year or more. Results were similar for those subjects with follow-up through 48 weeks after repeated treatment. The median volume required for repeated treatment with Juvéderm was significantly less than that for initial treatment (0.7 ml versus 1.6 ml). CONCLUSION: Juvéderm Ultra Plus provides correction of severe nasolabial folds through 1 year or more.

RESUMO

BACKGROUND: A new family of next-generation non-animal hyaluronic acid (HA) dermal fillers was approved by the FDA in June 2006. Compared with other HA fillers available in the United States at the time of writing, these new fillers have a higher concentration of HA, higher concentration of cross-linked HA, and a smooth consistency--which should promote long-lasting corrections and a smooth, natural look and feel postinjection. OBJECTIVE: The objective was to compare the effectiveness and safety of these smooth-gel HA dermal fillers with bovine collagen for nasolabial fold (NLF) correction. METHODS AND MATERIALS: A total of 439 subjects with moderate or severe NLFs received one of three types of smooth-gel HA dermal filler (in one NLF) and cross-linked bovine collagen (in the other NLF) and were evaluated for or=6 months. Up to 88% of subjects preferred the HA dermal fillers over bovine collagen. All fillers were similarly well tolerated. CONCLUSION: The smooth-gel HA dermal fillers offer longer-lasting correction than bovine collagen-which may lessen the frequency that repeat treatments are needed. Also, they were preferred by the vast majority of subjects-which should promote patient satisfaction.

RESUMO

Peptide cosmeceuticals are one of the new, popular options to treat aging skin. There are three main categories of cosmeceutical peptides: signal peptides, neurotransmitter-affecting peptides and carrier peptides. Although their benefits currently may not be as rigorously tested as most FDA-regulated drugs, the evidence to support their use is growing. This article attempts to review the various current popular cosmeceutical peptides, the published studies on their theoretical effects, and their practical use in dermatology.

RESUMO

Dermatosis papulosis nigra (DPN) is a very prevalent skin condition among certain ethnic groups, especially African-Americans and Afro-Caribbeans. The histology is not significantly different from that of seborrheic keratosis. DPN does not pose any health dangers, but patients often seek removal due to aesthetic concerns since it occurs commonly on the face. When performing any elective procedure, it is important that great care is taken to prevent complications so as to not merely exchange one defect for another such as a scar or discoloration. This article will outline options for management of this common cosmetic problem.

RESUMO

Nonsurgical procedures have become very popular for the rejuvenation of the aging face. Trends now are for less invasive procedures as well as for more preventative intervention to slow the damage from ultraviolet light and environmental factors, as well as from intrinsic aging. The goal of these procedures is to eliminate or delay the need for corrective surgery. The regular use of sunscreens; retinoids and improved cosmeceuticals; injectable neurotoxins; soft-tissue augmentation products; and minimally invasive laser, light, and radiofrequency treatments are decreasing and delaying need for invasive procedures. Injectable fillers entered mainstream cosmetic medicine with the development of bovine collagen injections in the 1980s. The availability of improved fillers that are less allergenic and longer lasting has resulted in a renaissance in filler techniques. No single filler has proven to be more popular than the category of hyaluronic acids (HA). This article will review the use of the hyaluronic acid fillers that are currently approved for use by the Federal Drug Administration in the United States and describe the significant differences between them to assist the practicing cosmetic physician in choosing and using this category of dermal filler.

RESUMO

BACKGROUND: Cosmeceuticals are skin care products that lie in a gray area between cosmetics and drugs. The desire for the improvement of aging skin has resulted in a plethora of products designed to improve the appearance beyond the simple camouflage of cosmetics. Many ingredients have been added to these products based on theoretical benefits discovered from in vitro studies on wound healing and other metabolic processes. OBJECTIVE: To help the practicing dermatologist who is often the source of information for patients regarding the benefits of available cosmeceuticals. METHODS AND MATERIALS: This article is a compilation of published studies on the effects and the practical applications of peptides as topical agents for skin improvement. RESULTS: There does seem to be science that shows that these peptide cosmeceuticals have the potential to improve the appearance of aging skin. It is important to remember, however, that for benefit to be realized, the final product must be stable in formula, absorbed into the skin, and biologically active at the target for clinical benefit. CONCLUSION: This article will provide dermatologists with more background to answer pressing questions from patients on this subject.
