The clinical efficacy and tolerability of a novel triple acid exfoliating blend for reducing signs of photoaging in sensitive skin.

BACKGROUND: Chemical exfoliation of the skin is a frequently utilized treatment in dermatology to improve the appearance and health of photoaged skin. Photodamaged skin is especially prone to dryness and irritation. Over-exfoliation with at-home products are partially to blame for the "epidemic" of sensitive skin affecting over half the population. Combining AHA, BHA, and PHA together creates a complementary blend that has the potential to target numerous age-related changes in the skin including the appearance of pores and smoothing skin texture, while firming skin and increasing its collagen and moisture content. OBJECTIVES: The following study tested the clinical efficacy of a triple acid blend designed specifically for sensitive skin and measured improvements in signs of photodamage and hydration levels in the skin over time. METHODS: Thirty females aged 35-60 with mild to moderate facial lines, wrinkles, sun damage, uneven skin tone/texture, dark spots, or pores were enrolled. Subjects were instructed to use the test article, DWB-EN, on a clean face at night 3 times weekly with 48 h between applications for 4 weeks. RESULTS: Statistically significant improvements were noted in all parameters of photoaging clinical assessments (wrinkles, pores, overall appearance, luminosity, visible texture, skin tone evenness, hyperpigmentation) at the end of the 4-week study period. There were no instances of skin irritation throughout the duration of this study despite half of the women having sensitive skin. CONCLUSIONS: Overall, this study demonstrated the clinical efficacy and tolerability of DWB-EN for treating photoaging in subjects with all skin types.

A clinical evaluation of the efficacy and tolerability of a novel topical antioxidant formulation featuring vitamin C, astaxanthin, and fermented turmeric.

BACKGROUND: Ultraviolet light, visible light, infrared light, and pollution are a few examples of environmental factors that exacerbate the formation of reactive oxygen species (ROS) that cause damage to skin cells' DNA, proteins, and lipids. By supplementing the skin with antioxidants, we can help neutralize ROS formed by these extrinsic factors before they can damage the skin. AIMS: This prospective open-label study explores the safety and efficacy of this novel topical formulation of antioxidants (vitamin C, astaxanthin, fermented turmeric, and vitamin E) designed to fight free radical damage and improve overall skin quality, as well as the appearance of fine lines, wrinkles, radiance, and hyperpigmentation of the skin. PATIENTS/METHODS: This single-center clinical study evaluated the efficacy of twice-daily application of the test article (Asta C™ Vitamin C Age Defense Serum, Dr. Whitney Bowe Beauty) in 32 subjects for 12 weeks. Healthy female subjects aged 35-60 with mild to moderate fine lines, wrinkles, and hyperpigmentation/uneven skin tone were enrolled in this study. Fitzpatrick skin types I-VI, all skin types (dry, normal, combination, oily), and subjects with sensitive skin were included. RESULTS: All subjects demonstrated improvement in overall skin quality (face, neck, and chest) by the end of the 12-week study period. One hundred percent of subjects demonstrated improvement in the appearance of fine lines at Week 12. CONCLUSIONS: Overall, the current clinical study demonstrates that Asta C™ is safe, well-tolerated, and effective in improving overall skin quality, as well as the appearance of fine lines, wrinkles, radiance, and hyperpigmentation of the skin.
