Dimethylsilanol Hyaluronate

What is Dimethylsilanol Hyaluronate?

Dimethylsilanol Hyaluronate is a synthetic derivative formed by linking hyaluronic acid—a naturally occurring polysaccharide typically produced via bacterial fermentation—with dimethylsilanol, an organosilicon compound. This chemical modification creates a more lipophilic molecule with improved skin penetration compared to unmodified hyaluronic acid. Commonly featured in serums, creams, and anti-aging formulations, it serves as a multifunctional ingredient in hydrating cosmetics. In products, it works by binding water molecules to form a hydrating network within the skin's upper layers, while the silanol component provides a lightweight film that smooths the surface and reduces transepidermal water loss. Its dual hydrophilic-lipophilic nature allows delivery of moisture to deeper strata, contributing to a non-greasy, velvety finish in leave-on applications.
