PHENYL TRIMETHICONE
Is PHENYL TRIMETHICONE safe for seborrheic dermatitis?
Phenyl Trimethicone is generally a lower-concern ingredient for seborrheic dermatitis. It improves slip and reduces moisture loss, but it is not an antifungal or seb derm treatment.
It is a silicone rather than a triglyceride oil or free fatty acid, and no ingredient-specific Malassezia concern was found. A rich or heavily layered formula can still feel occlusive or be difficult to remove for some people, so evaluate the complete product rather than treating the silicone name as a safety guarantee.

What is PHENYL TRIMETHICONE used for in skincare?
Phenyl Trimethicone is a silicone fluid modified with phenyl groups to give shine, smooth spread and a silky conditioned feel. In skincare and haircare it can reduce tack, soften the surface and form a light water-resistant film. It is often combined with other silicones, emollients and film formers in moisturisers, sunscreens and styling products.
