Retinyl palmitate

Retinyl PalmitateActive

Ester form of vitamin A. Mildest retinoid — also the least clinically effective.

What it does

Retinyl palmitate must be converted twice (to retinol, then to retinoic acid) before becoming active. Common in moisturizers and SPF products as a marketing-friendly retinoid that rarely irritates. Evidence for visible benefit is limited compared to retinol or tretinoin.

The evidence, graded

strongAll topical retinoids — tretinoin, adapalene, retinol, retinaldehyde, retinyl palmitate, and hydroxypinacolone retinoate — are not recommended during pregnancy. Direct human data exist mainly for the prescription retinoids (tretinoin, adapalene); the caution extends to the others as a precautionary class-effect. Data on inadvertent exposure reassure but aren't strong enough to recommend any retinoid in pregnancy.Kaplan 2015 · British Journal of Dermatology

Graded per the methodology: strong · moderate · emerging · expert consensus. A weak source on a strong claim gets the weaker label.
