Quick Summary
Skin hydration and plumping — holds 1000x its weight in water
Also called: HA, Sodium Hyaluronate, Hyaluron
What is Hyaluronic Acid?
Hyaluronic acid is a naturally occurring glycosaminoglycan found throughout the body, with the highest concentrations in skin, joints, and eyes. As a skincare active, it acts as a powerful humectant, drawing moisture from the environment and deeper skin layers to the surface. This creates immediate plumping and hydration effects that reduce the appearance of fine lines and improve skin texture. Depletes naturally with age — topical HA replenishes surface hydration.
How It's Made
Cosmetic HA is produced via bacterial fermentation (Streptococcus equi) or through chemical synthesis. Available in multiple molecular weights — low MW penetrates deeper, high MW provides surface hydration.
