Should I be concerned about Vitamin A in my sunscreen?
Yes. We avoid the use of Retinyl Palmitate (Vitamin A) as data from an FDA cancer study showed that when used with a sunscreen ingredient, the formula may speed the growth of skin tumors. These effects happen only when retinyl palmitate or other forms of vitamin A are used on skin in the presence of sunlight. The study of retinyl palmitate toxicity was conducted by scientists at the FDA and the National Toxicology Panel (NTP 2012). Their findings reinforced earlier data identifying health risks of vitamin A in sun-exposed skin care products.
