Mechanism of action

Hyaluronic acid (HA) is a naturally occurring polysaccharide that binds water molecules, providing hydration and volumization to the skin. When injected into the dermis, HA fillers restore lost volume, smooth wrinkles, and enhance facial contours through mechanical filling and water-binding properties. The filler gradually integrates with surrounding tissue and is metabolized over time, typically lasting 6–12 months depending on formulation and injection site.
