About this ingredient

Phytosphingosine is a naturally-derived sphingoid base extracted from plant sources such as rice bran and wheat that functions as a skin-conditioning agent. It strengthens the skin barrier by supporting ceramide synthesis and promoting intercellular lipid organization, thereby improving skin hydration, reducing transepidermal water loss, and enhancing overall skin resilience.
