Science & Benefits

Phenyl Trimethicone is a branched silicone with a high refractive index, providing significant shine and 'gloss' to a formula. It is more compatible with skin lipids and organic oils than standard dimethicone. While zero-comedogenic, it is more substantive and less volatile. For acne users, it is a 'Good' emollient that provides a healthy glow, but should be used sparingly in leave-on products for those with extremely oily complexions.
