Sunscreen Ingredient Poses No Cancer Threat, Dermatologists Say

August 9, 2010: 11:37 AM EST
An analysis of available in vitro and animal studies by several dermatologists has found no evidence to support a recent warning from the Environmental Health Group that retinyl palmitate, a cosmetic ingredient in sunscreens, poses a risk of cancer. Dr. Steven Q. Wang said no clinical studies have been conducted on the potential of retinyl palmitate or other retinoids to cause cancer. But “observations from decades of clinical practice do not support the notion that retinyl palmitate in sunscreen causes or promotes skin cancer.” Sunscreens crucial for reducing skin cancer risk. Retinyl palmitate is FDA-approved for use in over-the-counter and prescription drugs, and is also used as a food additive. It serves as an antioxidant in sunscreens to mitigate the aging effects of UV exposure.
