RESUMO

Acne vulgaris (AV) is one of the top concerns dermatologists encounter from women. Until now, therapies addressing AV have largely centered around, and have been successful at, targeting the pathophysiological mechanisms that occur at the pilosebaceous unit: sebum hypersecretion, follicular keratinization, over-proliferation of Cutibacterium acnes, and a localized immune response. In addition to these, there is good evidence to suggest that other systemic drivers of a generalized inflammatory response may contribute to the development or exacerbation of acne and that addressing these underlying factors may open more opportunities for developing effective treatments. These include psycho-emotional stress, diet and metabolism, hormonal fluctuations, skin and gut microbiome, oxidative stress, and immune response. While there is accumulating evidence that vitamins, minerals, and botanicals may mitigate some of the pro-inflammatory effects from the activation of these underlying systems, their use and recommendations are limited by a lack of quality efficacy and safety evidence. Here, we present the current evidence for the use of individual supplements in addressing the 6 systemic underlying drivers of AV. We also present a clinical study on the safety and efficacy of a nutraceutical combining many of these ingredients in the management of AV in men and women.  J Drugs Dermatol. 2024;23(3):160-167     doi:10.36849/JDD.8138.

RESUMO

Acne Vulgaris (AV) is a prominent skin disease commonly affecting teenagers. It often persists into adulthood and is associated with adverse physical and psychosocial impacts. The pathophysiology of AV is conventionally correlated with 4 factors within and around the pilosebaceous unit: increased sebum production, follicular hyperkeratinization, Cutibacterium acnes proliferation, and localized immune responses. As such, conventional therapeutic approaches for AV have primarily focused on these factors. In addition to this primarily localized pathophysiology, there is a progressively emerging body of evidence indicating that underlying systemic factors contributing to a generalized immuno-inflammatory response can contribute to or exacerbate AV. In this article, we introduce and provide the supporting data, for 6 patient-centric systems that may be implicated in the development of AV: psycho-emotional stress, diet and metabolism, dysbiosis of the gut and skin microbiome, hormonal fluctuations, oxidative stress, and immune response. Identifying these pathways and their contributions in a patient-centric approach may provide expanded therapeutic opportunities for treating patients with AV.

RESUMO

Our current understanding of the pathogenesis of skin aging includes the role of ultraviolet light, visible light, infrared, pollution, cigarette smoke and other environmental exposures. The mechanism of action common to these exposures is the disruption of the cellular redox balance by the directly or indirectly increased formation of reactive oxygen species that overwhelm the intrinsic antioxidant defense system, resulting in an oxidative stress condition. Altered redox homeostasis triggers downstream pathways that contribute to tissue oxinflammation (cross-talk between inflammation and altered redox status) and accelerate skin aging. In addition, both ultraviolet light and pollution increase intracellular free iron that catalyzes reactive oxygen species generation via the Fenton reaction. This disruption of iron homeostasis within the cell further promotes oxidative stress and contributes to extrinsic skin aging. More recent studies have demonstrated that iron chelators can be used topically and can enhance the benefits of topically applied antioxidants. Thus, an updated, more comprehensive approach to environmental or atmospheric aging protection should include sun protective measures, broad spectrum sunscreens, antioxidants, chelating agents, and DNA repair enzymes.

RESUMO

Hair loss is a complicated problem that causes significant concern for those who are affected. Patients seeking medical treatment have limited options that include topical minoxidil and oral finasteride. While these treatments are backed by long term clinical use and research outcomes, many patients find topical minoxidil difficult to incorporate into their daily routine and some are concerned with the side effects associated with finasteride. In the office setting, patients may be treated with more invasive procedures such as platelet-rich plasma injections (PRP) and hair transplantation, treatments that often must be repeated and can lead to a costly investment. Consumers are increasingly interested in natural treatments for hair loss. Many turn to basic supplements only to be disappointed when they fail to deliver due to lack of standardization and efficacy. In this paper we review the benefits of a nutraceutical containing a specific blend of highly purified, standardized, bio-optimized, and bioavailable botanical extracts to treat hair loss. These phytoactives were selected because of their diverse multi-modal biologic activity against inflammation, DHT, stress mediators, oxidative damage, and intermediary signaling cascades. This supplement represents a paradigm shift as it addresses not only the factors that trigger hair loss but the downstream mediators of inflammation as well. Multi-center clinical studies are currently underway to confirm the efficacy and benefits of this unique nutraceutical.

RESUMO

Facial lines and wrinkles are caused by many factors including constant exposure to external elements, such as UV rays, as well as the dynamic nature of facial expression. Many cosmetic products and procedures provide global improvement to aging skin, whereas injectable therapies are frequently utilized to diminish specific, target wrinkles. Despite their broad availability, some patients are unwilling to undergo injectables and would benefit from an effective topical option. A noninvasive option to volumize target wrinkle areas could also extend benefits of commonly used cosmetic anti-aging products. To this end, a two-step formulation containing the novel, cosmetic anti-aging ingredient, N-acetyl tyrosinamide, was developed for use on targeted wrinkle areas. The tolerability and efficacy of the serum plus cream were tested for 16 weeks in women with moderate facial photodamage on predetermined wrinkle areas (glabellar lines, nasolabial folds, under eye lines, and lateral canthal (crow's feet) wrinkles) in a single-center, randomized, double-blind, vehicle-controlled, clinical trial. Seventy women (47 Active group, 23 Vehicle group) completed the study. Digital photography, clinical grading, ultrasound and self-assessment scores confirmed improvement to wrinkle areas. The topical cosmetic formulation was statistically superior (P<0.05) to its vehicle in visually improving nasolabial folds, glabellar lines, crow's feet, and under eye wrinkles and in reducing pinch recoil time. Both the test formulation and its vehicle were tolerated well. The novel, two-step cosmetic formulation reduced the appearance of wrinkles and increased skin elasticity thus providing an effective anti-aging option for target wrinkle areas. This study suggests that in addition to its use as monotherapy for reducing targeted lines and wrinkles this cosmetic formulation may be also serve as an adjuvant to injectable therapies.

RESUMO

Skin aging is a multifaceted biological process characterized by the appearance of wrinkles, pigmentation irregularities, and loss of firmness. These symptoms cannot be fully addressed by any single skin care ingredient or noninvasive cosmetic procedure. A comprehensive treatment approach, including the use of clinically proven topical skin care formulations, provides optimal antiaging effects. A high-strength skin care regimen (NeoStrata® Skin Active; NeoStrata Company, Inc, Princeton, NJ) was developed to deliver a combination of more than 35% active benefit ingredients, including the.

RESUMO

Skin aging is a combination of natural aging with superimposed photoaging. Naturally aged skin is thin, fragile and finely wrinkled whereas photoaged skin is rough and thickened with deep coarse wrinkles. In addition photoaging is characterized by mottled pigmentation, solar lentigines, telangectasias and a loss of elasticity. The science behind skin aging has exploded in the past decade. Skin aging has now been defined on both a cellular and molecular level. The study of genomics in aging skin provides us with potential targets as points for intervention. In this regard, the science behind skin aging becomes a platform for the development of new anti-aging strategies and products. In this paper two new and emerging approaches to treat aging skin will be discussed. Sirtuin activating and anti-glycation products are already being marketed by cosmetic and pharmaceutical companies. These anti-aging approaches are backed by basic science research and the ingredients used are supported by proof of concept studies although clinical trials are often lacking. It is this bench to beauty counter approach to cosmeceuticals that remains an industry standard today.

RESUMO

BACKGROUND: Cosmeceuticals containing antioxidants are among the most popular antiaging remedies. Topically applied antioxidants exert their benefits by offering protection from damaging free radicals produced when skin is exposed to ultraviolet light or allowed to age naturally. Vitamin C is a naturally occurring potent water-soluble antioxidant. Accordingly, it has been incorporated into a variety of cosmeceuticals designed to protect and rejuvenate photoaged skin. OBJECTIVE: This article reviews the scientific data and clinical studies supporting the use of topically applied vitamin C for treating photoaged skin. Other innovative uses for vitamin C cosmeceuticals are also discussed. CONCLUSION: A significant body of scientific research supports the use of cosmeceuticals containing vitamin C. Cutaneous benefits include promoting collagen synthesis, photoprotection from ultraviolet A and B, lightening hyperpigmentation, and improvement of a variety of inflammatory dermatoses. Because of the diverse biologic effects of this compound, topical vitamin C has become a useful part of the dermatologist's armamentarium.

RESUMO

Solar lentigines are benign, hyperpigmented lesions that present a significant cosmetic nuisance for many middle-aged and elderly patients with chronic accumulated sun exposure. While previous monotherapies designed to lighten these lesions offer relatively modest improvement, there are several new treatment options. Combination topical therapy using 2% mequinol/0.01% tretinoin [Solagé Topical Solution] has been shown to markedly reduce lesion darkness with few side effects. Chemical peels can give good results either alone or in combination with topical therapy. Cryotherapy is an effective and inexpensive way of treating solar lentigines while IPL and lasers are more costly treatment options. For patients desiring treatment, optimal cosmetic improvement can be achieved using a combination of topical and procedural therapies.

RESUMO

Chondrodermatitis nodularis helicis (CNH) is a disorder that affects adults. Only one case of juvenile CNH has been reported, in an 8-year-old child who suffered from dermatomyositis. We report another child with juvenile CNH who was not afflicted with dermatomyositis or other systemic disorders. The clinical and histologic evaluations demonstrated CNH on the helix of the right ear in a 16-year-old Caucasian girl who was otherwise healthy. Serologic analysis ruled out an underlying autoimmune disorder. We conclude that juvenile CNH is extremely rare and may occur in patients without dermatomyositis or other systemic disorders.

RESUMO

BACKGROUND: This investigation was initiated because of a growing concern by the American Society for Dermatologic Surgery about the proliferation of nonphysicians practicing medicine and its impact on public health, safety, and welfare. OBJECTIVE: Prompted by an alarming rise in anecdotal reports among dermatologic surgeons, the study sought to determine whether there was a significant increase in the number of patients seeking corrective treatment due to complications from laser and light-based hair removal, subsurface laser/light rejuvenation techniques, chemical peels, microdermabrasion, injectables, and other cosmetic medical/surgical procedures performed by nonphysicians without adequate training or supervision. METHODS: A survey of 2,400 American Society for Dermatologic Surgery members in July 2001 and in-depth phone interviews with eight patients who experienced complications from nonphysicians performing cosmetic dermatologic surgery procedures were conducted. RESULTS: Survey data and qualitative research results attributed patient complications primarily to "nonphysician operators" such as cosmetic technicians, estheticians, and employees of medical/dental professionals who performed various invasive medical procedures outside of their scope of training or with inadequate or no physician supervision. CONCLUSION: The results underscore the need for improved awareness, legislation, and enforcement regarding the nonphysician practice of medicine, along with further study of this issue.

RESUMO

BACKGROUND: Microdermabrasion is widely performed in a number of clinical settings, including medical offices, salons, and spas. This procedure is generally regarded as safe and easy to perform. OBJECTIVE: To determine if latex exposure caused an acute urticarial response following microdermabrasion in a latex-allergic patient. METHODS: The patient was prick tested to saline and histamine controls, latex, and sterile medical grade 100 m aluminum oxide crystals that had been passed through the microdermabrader. RESULTS: The strongly positive latex prick test confirmed latex allergy in our patient. Negative prick testing to aluminum oxide crystals that had passed through the microdermabrader make it unlikely that the patient was exposed to latex via this system. CONCLUSION: Physicians need to carefully evaluate patients who are considering microdermabrasion and appreciate that unexpected serious complications can occur.
