Dimethicone
Polydimethylsiloxane (PDMS), silicone
Dimethicone is a common silicone that forms a light, breathable occlusive layer on the skin. It slows water loss and leaves a smooth, silky finish. It is used in moisturizers and primers because it fills in fine texture and gives skin a polished look.
Benefits of Dimethicone
