Dimethylsilanol Hyaluronate

What Dimethylsilanol Hyaluronate is & what it does

Dimethylsilanol Hyaluronate is a silanol-modified form of hyaluronic acid, combining the water-binding hyaluronate backbone with an organosilicon group. In skincare and sunscreen formulas it acts as a conditioning and humectant agent that helps the skin hold moisture while leaving a light, silky finish. A notable property is that the silanol modification is intended to improve spreadability and skin affinity compared with plain hyaluronic acid.
