Phytosphingosine
Phytosphingosine is a skin-friendly lipid naturally found in the outer layers of healthy skin. In skincare it is used as a gentle conditioning and protective ingredient that helps reinforce the skin’s natural barrier and maintain a balanced microbiome.
How it works in skincare
In cosmetic formulations phytosphingosine works as a ceramide precursor and skin-identical lipid that integrates into the intercellular matrix of the stratum corneum. It helps reduce moisture loss, supports the skin’s natural defence system and has mild antimicrobial properties that can help keep unwanted bacteria in check without stripping the skin. You will often find it in moisturisers, serums and barrier-supporting creams where it enhances texture and improves the overall feel of the product on the skin.
