About this ingredient
Phosphatidylcholine is a phospholipid, a core building block of cell membranes and liposomes. For cosmetics it is most often sourced from soy or sunflower. INCI: Phosphatidylcholine. In a formula it works as an emulsifier, conditioning agent, and carrier: it forms liposomes that help spread and deliver other components, and it is related to skin lipids. It is used in creams, serums, and active-delivery systems. As a lipid component it supports skin softness and smoothness. Pregnancy safety. Topical use, low systemic absorption, no evidence of harm. It can be used during pregnancy and lactation. Tolerance. Irritation and allergen potential are low. Its main role is functional: an emulsifier and carrier rather than a standalone active.
