Topical Vitamin C Protects Skin

With summer here, we're all aware that the current gold standard sunscreen is a must. However, in a clinical trial performed by Sheldon R. Pennell, Chief Emeritus of Dermatology at Duke University Medical Center, the study shows that sunscreen alone is often insufficient due to inadequate use, uneven application, insufficient amount, sweating, rub off, etc. Studies show that antioxidants paired with sunscreen are crucial to help protect against skin cancer and photodamage (sun damage). UVB rays (the rays that burn your skin) are a direct carcinogen and can cause squamous cell carcinomas leading to DNA mutation and a higher risk for developing melanoma on parts of your body (including internal organs) that have not been exposed to the sun. Topical L-ascorbic acid (vitamin C) is an antioxidant that has been clinically proven to provide substantial protection for human skin from inflammation and DNA mutation related to skin cancer caused by sun exposure. In the same clinical trial, 55 women age 35-65 applied a 20% topical vitamin C once a day for 24 weeks. By the third day, the skin was completely saturated. By week 8 more than 79% of participants were satisfied with the overall appearance of their skin, more than 77% felt the topical product reduced the appearance of fine lines and wrinkles and more than 62% saw a reduction in brown spots and hyperpigmentation.
Consider the following when choosing a topical vitamin C. These clinical trials were performed using a 20% L-ascorbic acid solution applied once a day with a pH of 3.5 or lower to penetrate the skin. Derivatives of L-ascorbic acid including magnesium ascorbyl phosphate, Ascorbyl-6-palmitate, and dehydroascorbic acid did not increase the levels of ascorbic acid in the skin. Read labels carefully watching for these ingredients since they do not equal L-ascorbic acid.
