What it is
Retinyl palmitate is a more stable, ester form of vitamin A in which retinol is combined with palmitic acid. In cosmetics it is used as a conditioning agent that, once in the skin, can be gradually converted toward more active retinoid forms, and it also contributes antioxidant character. It is a relatively gentle member of the vitamin A family commonly found in moisturizers and sun care.
Safety & warnings
Retinyl palmitate is among the milder vitamin A derivatives and is generally well tolerated, though retinoids can cause dryness or irritation in sensitive users. Like other vitamin A ingredients, it can degrade with light and air exposure, so it is typically stabilized and kept in protective packaging.
Origin & sourcing
It is produced synthetically by esterifying retinol (vitamin A) with palmitic acid, a common fatty acid.
