Retinyl Palmitate
What is Retinyl Palmitate?
Retinyl Palmitate is the ester of retinol (Vitamin A) and palmitic acid, a fat-soluble form of vitamin A commonly used in skincare products for its antioxidant properties and role in skin cell renewal. It is considered a milder derivative compared to pure retinol, as it requires two conversion steps in the skin to become active retinoic acid, which helps promote collagen production and improve skin texture. Widely incorporated into moisturizers, sunscreens, and anti-aging formulations for its stability and gentle efficacy.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Antioxidant
Slows oxidation of oils, fragrances, and sensitive actives to improve shelf life and reduce rancidity or color change; sometimes also supports skin protection from oxidative stress.
