Phenyl TrimethiconeBarrier
A shine-adding silicone — mostly in hair serums and lip products, where it brings gloss and slip rather than moisture.
What it does
It’s a silicone tweaked to reflect more light, so it adds more shine than plain dimethicone. It’s common in hair serums, brow gels and some lip products. In face products it adds slip and shine rather than moisture.
