Hyaluronic acid is a humectant, or water-holding molecule, that helps keep skin plump and hydrated. Sodium hyaluronate is the sodium salt of hyaluronic acid (HA). It can hold many times its weight in water.
Hyaluronic acid is the natural gel between skin cells that serves as their water reservoir. As we age, skin loses hyaluronic acid and the ability to hold enough water in this reservoir. Topically applying HA can boost water stores in this intercellular reservoir, raise skin’s moisture level, and smooth fine lines.
We use hyaluronic acid with a “super low” molecular weight (SLMW) for its optimal ability to penetrate the skin. SLMW HA has a molecular weight between 8k-15k Daltons and can absorb thoroughly into the skin rather than remaining on its surface. It can help transport active ingredients and hydrators into the skin to improve formula effectiveness while plumping skins’ appearance from within. This vegan HA is produced through bacterial fermentation of plant matter (usually beans and potatoes).
