Retinyl Palmitate

Retinyl palmitate is the ester of retinol and palmitic acid — the gentlest and most stable common vitamin A form. It must undergo two conversion steps (to retinol, then retinaldehyde, then retinoic acid), so its biological activity per gram is the lowest of the retinoid family. That weakness is also its strength: it is well tolerated by retinoid beginners and sensitive skin, rarely causes peeling, and still delivers mild smoothing and barrier-supporting benefits at 0.1–1%. It is ubiquitous in department-store creams where comfort outranks potency. Realistic expectations matter: for significant anti-aging results, stronger retinoids are more effective — but as an entry-level, daily-wear vitamin A it is reliable and safe.
