Phytosphingosine

What it does

Phytosphingosine is a long-chain amino alcohol naturally found in skin that serves as a building block for ceramides—critical lipids in the stratum corneum. It works to restore and maintain the skin's lipid barrier, enhancing hydration and structural integrity. Often used in barrier-repair and sensitive-skin formulations.
