RESUMO
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.
