What Is Hyaluronic Acid?

Hyaluronic Acid—aka HA or Sodium Hyaluronate—is a naturally occurring substance within our skin that has great moisture-absorbing properties. It even has different ranges of molecular weights (more on that later).

How Does Hyaluronic Acid
Work In Skin?

Meet the ingredient that helps give skin hydrated bounce. Hyaluronic Acid acts like a sponge to draw moisture to skin; helps replenish its moisture reserves; helps to retain water and keep skin hydrated; and helps visibly plump fine, dry lines. Remember the molecular weights? Here’s what we know: low molecular weight HA triggers skin to produce more of this moisture-binding substance while high molecular weight HA has been shown to help hold water to skin’s surface.
