Hyaluronic Acid (HA) is a glycosaminoglycan found naturally in the skin's extracellular matrix. It acts as a humectant, meaning it draws moisture from the environment into the skin.
Its unique molecular structure allows it to bind and retain water molecules significantly, providing essential hydration and structural support (turgidity) to the dermis.
Scientific Properties:
- High molecular weight hydration
- Maintains extracellular space volume
- Facilitates nutrient transport to cells
