Phytosphingosine
What is Phytosphingosine?
Phytosphingosine is a sphingoid base, chemically known as 4D-hydroxysphinganine, naturally present in plants like rice bran, yeast, and mammalian skin. This long-chain amino alcohol serves as a precursor to ceramides, key components of the skin's lipid barrier. In cosmetics, it functions primarily as a skin and hair conditioning agent in moisturizers, serums, and cleansers. It integrates into the stratum corneum's lipid matrix to enhance barrier integrity, reduces transepidermal water loss, and exhibits antimicrobial properties by disrupting bacterial cell membranes. Additionally, it modulates inflammation and promotes keratinocyte differentiation, contributing to smoother, more resilient skin texture. Derived synthetically for purity in formulations, it mimics the skin's native lipids to maintain hydration and suppleness without greasiness.
