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 synthetic silicone-based polymer developed as part of the cosmetics industry's innovation in the late 20th century. Created to improve the sensory profile and conditioning properties of skincare products.
