What it is
A naturally occurring phospholipid mixture typically derived from soybeans, eggs, or sunflower, widely used in skincare as an emulsifier and skin-conditioning emollient. It helps blend oil and water phases and contributes to a smooth, silky skin feel.
How it works
Its amphiphilic phospholipid structure — a hydrophilic head and lipophilic tails — lets it sit at oil-water interfaces and stabilize emulsions, while also integrating into the skin's own lipid structure to support barrier softness.
