Silicone resins are resinous substances composed of siloxane segments and organic groups. With excellent water and oil resistance, they provide long-lasting effects in cosmetics.

In skincare, silicone resins are often used in sunscreens and primers. They form a protective barrier that prevents water and oil penetration while enhancing the product's water and oil resistance for longer wear.

In color cosmetics, silicone resins improve adhesion and longevity. For example, adding them to eyeliners ensures smudge-proof wear, while incorporating them into mascaras delivers longer-lasting, clump-free results.
