Efficacy and safety of a new superficial chemical peel using alpha-hydroxy acid, vitamin C and oxygen for melasma

Clinical Assessment, Diagnosis, and Management of Infraorbital Wrinkles and Pigmentation

Lower eyelid skin is unique and different from that of other areas. In addition to being an area of high exposure to the sun and elements, there are anatomic considerations and specific histologic characteristics that can cause the skin in this area to be more sensitive. These attributes can readily cause under-eye wrinkling and pigmentation. This review aims to present an updated overview of the current knowledge regarding the clinical characteristics, diagnosis, and management of wrinkles and pigmentation in this area. These disorders are usually caused by different factors, such as genetics, aging, sun exposure, lack of sleep, and stress.

Comparative evaluation of therapeutic efficacy and safety of black peel versus 25% trichloroacetic acid peel in mild to moderate acne vulgaris: a split face study

Introduction

Peeling has withstood the test of time as a simple, minimally invasive method to renew the skin, despite the introduction of more advanced procedures like lasers.

Materials and Methods

Thirty patients (or 60 sites) with age ranging from 15 to 45 years with mild-to-moderate acne vulgaris were included in the study. Assessment at baseline was done by the global acne grading system score for including mild and moderate acne patients.

Results

On grading the improvement according to the 5-point Global Assessment Scale (GAS), it was found that in area A (black peel), 6.7% of patients showed excellent improvement, 86.7% of patients showed good improvement, and 6.7% of patients showed fair improvement. In area B (25%TCA peel), 6.7% of patients showed excellent improvement, 80% of patients showed good improvement, and 13.3% of patients showed fair improvement.

Discussion

None of the patients showed poor or worse outcomes in any of the areas. The difference between the groups was not significant (P = 0.688).

Conclusion

There is a paucity of data in the literature regarding the comparison of black peel with other conventional peels in the treatment of acne vulgaris. To the best of our knowledge, this is the first study comparing black peel with TCA peel in the treatment of acne vulgaris.

Treatment of mild-to-moderate facial cutaneous aging using a combination peel containing 6% trichloroacetic acid and 12% lactic acid

Chemical peeling treats facial cutaneous aging and may avoid risks in patients with sensitive skin, darker skin types, limited finances, or concern for side effects of other resurfacing techniques. Tolerability and improvement of photoaging using a combination peel containing 6% trichloroacetic acid and 12% lactic acid for treatment of mild-to-moderate signs of facial photoaging were assessed. This is a prospective, single-center, single-arm, study of 32 female subjects with mild-to-moderate signs of facial aging and Fitzpatrick Skin Types I-V treated with three monthly treatments of a combination peel containing 6% trichloroacetic acid and 12% lactic acid. After 3 treatments, there were statistically significant improvements in clarity, brightness, redness, pigmentation, fine lines, tactile and visual roughness, and overall appearance scores. Subjective improvements in photoaging parameters varied from 53% (fine lines) to 91% (clarity/brightness). Three treatments with a combination peel containing 6% trichloroacetic acid and 12% lactic acid achieved improvements in signs of facial photoaging. This procedure is safe and effective at treating cutaneous aging for all skin types and a viable option for patients who wish to avoid other resurfacing techniques such as laser resurfacing, microneedling among others.

TFOS Lifestyle: Impact of cosmetics on the ocular surface

In this report the use of eye cosmetic products and procedures and how this represents a lifestyle challenge that may exacerbate or promote the development of ocular surface and adnexal disease is discussed. Multiple aspects of eye cosmetics are addressed, including their history and market value, psychological and social impacts, possible problems associated with cosmetic ingredients, products, and procedures, and regulations for eye cosmetic use. In addition, a systematic review that critically appraises randomized controlled trial evidence concerning the ocular effects of eyelash growth products is included. The findings of this systematic review highlight the evidence gaps and indicate future directions for research to focus on ocular surface outcomes associated with eyelash growth products.

Treatment of melasma: a review of less commonly used antioxidants

Melasma, a common cause for seeking dermatologic care, is a chronic condition of skin hyperpigmentation. With a poorly understood pathogenesis, and no universal cure, melasma is a challenge for many dermatologists. For decades, there has been investigation into the role of oxidative stress in melasma. In this literature review, we introduce the role of oxidative stress in melasma and discuss the function of various topical and oral antioxidant therapies for patients suffering from melasma. Numerous studies have shown efficacy of various antioxidant therapies for treatment of hyperpigmentation, and in this review, we focus primarily on those with less widespread use. Vitamin E, niacinamide, polypodium leucotomos, pycnogenol, grape seed extract, amino fruit acids, phytic acid, zinc, silymarin, Korean red ginseng powder, plant extracts, and parsley all have well-demonstrated evidence of antioxidant properties, and these substances have been studied in the context of skin hyperpigmentation. Although there is conflicting evidence of their therapeutic efficacy, the use of these naturally occurring substances is promising for patients and medical providers seeking alternative therapeutic options.
