Recently, in the media, there have been comments alleging a relationship between vitamin A in sunscreen and increased risk of melanoma. The good news is that this connection is not supported by published scientific evidence. 

After reviewing the recently released report from the Environmental Working Group, Warwick Morison, MD, and Henry Lim, MD, both members of The Skin Cancer Foundation’s Photobiology Committee have concluded that there is no scientific evidence to support claims that retinyl palmitate (vitamin A) is a photocarcinogen in humans.   "We are unaware of any evidence that supports the relationship between the use of sunscreen containing retinyl palmitate and an increased risk of skin cancer," they said.
When used as directed, sunscreen products are safe and effective. Since our inception, The Skin Cancer Foundation has always recommended using a sunscreen with an SPF of 15 or higher as one important part of a complete sun protection regimen that includes seeking the shade and covering up with clothing.
