Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Locks In Moisture
Traditional Use
A contemporary cosmetic ingredient combining PEG with mushroom-derived glycerides. Mushrooms have been used in traditional Asian skincare for centuries, but this PEGylated version was created to enhance bioavailability and texture in modern formulations.
