Functions
Emulsion Stabilising
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Cleansing
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
Locks In Moisture
Traditional Use
A naturally occurring phospholipid found in cell membranes; historically part of traditional fat-based skincare preparations. Modern skincare uses it as a skin-conditioning and hydrating agent derived from plant sources.
