Phenyl Trimethicone
Phenyl Trimethicone is a silky, lightweight silicone ingredient commonly used in UK beauty products to give hair and skin a smooth, glossy finish without feeling heavy or greasy.
How it works in skincare
In cosmetics and skincare, Phenyl Trimethicone works as an emollient and conditioning agent that forms a breathable, protective film on the surface of skin or hair. This helps to reduce friction, improve spreadability of products, and lock in moisture while delivering a non-greasy, high-shine finish. It is frequently found in serums, primers, hair oils, conditioners and foundations where slip, shine and a soft after-feel are desired.
