Background There is an increasing demand for facial skin rejuvenation. Specialized aesthetic skincare treatments may be one of the first steps to help prevent or treat facial signs of aging. This article discusses aesthetic skin care for facial skin rejuvenation, particularly data on two creams containing Macrocystis pyrifera ferment. Methods The authors convened a dermatology advisory board to discuss challenges and practices in using skincare for facial rejuvenation, combining their expert opinion and experience on facial rejuvenation with preclinical and clinical data on two creams containing Macrocystis pyrifera ferment and a review of the literature. Results Preclinical and clinical studies on Macrocystis pyrifera ferment and two creams containing the ferment exhibit anti‐inflammatory, anti‐aging, and healing properties. In preclinical studies, the ferment demonstrated collagen type I enhancing properties in ex vivo skin models, and skin cells treated with the ferment migrated faster than untreated cells in the in vitro study. In clinical studies measuring visible anti‐inflammatory activity, the ferment alone and the ferment‐containing products significantly decreased erythema, and in anti‐aging studies, they improved visible skin aging parameters. Finally, in clinical studies on the stratum corneum, the two creams increased moisture levels and decreased transepidermal water loss (TEWL), reflecting healing by enhancing barrier strength and recovery. Conclusions The Macrocystis pyrifera ferment and creams containing the ferment are effective skin care treatment products to decrease the visible effects of inflammation and signs of aging while promoting healing by enhancing barrier resilience and recovery.

Introduction: Acne is the most common reason for dermatology consultation in adolescents and young adults. Consultation is often delayed despite unsuccessful self-treatment. Postponing effective treatment places acne sufferers at higher risk for permanent acne scars and post-inflammatory pigment changes. Aim: This review discusses clinical challenges with present therapeutic options for acne treatment and the role of a 1726 nm laser for acne. Methods: Current acne treatment guidelines were reviewed. A literature review was conducted for trials of light-based acne therapy. The selectivity of previous light-based therapies was reviewed. Results: Available acne therapy is effective, but treatment-related side effects are common. Acne treatment guidelines do not include recommendations for light-based treatments. Different types of light-based treatments have been tried but until now no wavelength specifically targeted sebaceous glands. Conclusion: The 1726 nm laser is safe and effective for treating mild to severe acne in all Fitzpatrick skin types. Acne resolution is apparent within the first month and improves for up to 2 years beyond treatment.
