Background: Due to ambient environmental- and lifestyle-associated stressors, the prevalence of acne in adult women has been increasing. Classical anti-acne treatments using benzoyl peroxide technology are associated with dehydration of the skin, which may accelerate aging and further reduce treatment compliance. The addition of bio-functional actives intended to replenish hydration and improve barrier function may hasten the onset of anti-acne benefits while restoring a healthy appearance and counteracting skin aging effects.

Background: Hyaluronic acid (HA) has been considered the gold standard ingredient for improving skin hydration and combating age-related effects, however it is an inefficient polymer with inconsistent results partially due to its poor skin penetration, surface deposition, and rapid degradation. Herein we report the synthesis and in vitro characterization of a newly developed, topical super-humectant with the goal of attracting and binding water molecules more efficiently than traditional, cosmetic-grade forms of HA.

Methods: A modified interpenetrating polymer network (IPN) was developed using three polymers into a three-dimensional formation (3D3P) for entrapping HA and water.

More men are beginning to take advantage of opportunities to improve the health and appearance of their skin; however, the effectiveness of men's skincare regimens has not been well studied. The authors investigated the efficacy and tolerance of a twice-daily, three-step men's skincare regimen in improving skin appearance and reducing shave-related issues. Twenty-nine men who used a wet-shaving method completed a specific, three-step, twice-daily facial regimen-a Shave Cleanser, a Post-Shave Treatment, and Day Protection-in place of their usual routine for 4 weeks.
