Hyaluronic acid holds up to 1000 times its weight in water. However, the molecule is naturally too large to penetrate the stratum corneum, meaning standard topical serums only hydrate the skin surface.
Dermal fillers inject cross-linked hyaluronic acid directly beneath the skin barrier, creating instant volume and structure. For topical formulas, look for hydrolyzed or multi-weight molecules that penetrate deeper.
Fillers typically last between 6 to 18 months, depending on the product type and individual metabolic rate.
