Phytosphingosine is a naturally occurring sphingolipid that supports the skin's lipid barrier and exhibits antimicrobial and anti-inflammatory properties, while allantoin is a soothing, keratolytic agent that promotes hydration and cell turnover. Used together, they aim to restore barrier function and calm irritated skin.
