Vitamin A causes photo sensitivity
The retinol and retinoic acid forms of vitamin A do make the skin photosensitive, but the retinyl palmitate form has extremely valuable photo-protective properties.
Research by the dermatology department at University Hospital Geneva showed that at high levels, topical retinyl palmitate was as efficient as an SPF20 sunscreen in preventing sunburn. However, UV light breaks it down, so also taking it as a supplement is recommended to support topical application.
