Ingredients

Hyaluronic Acid draws and locks moisture deep within the skin, holding up to 1000x its weight in water, while Squalane mimics the skin's own oils for lightweight, non-clogging hydration, creating a formula that addresses multiple needs at once.

Hyaluronic acid is a glycosaminoglycan naturally present in the dermis. When applied topically, low-molecular-weight HA penetrates beyond the surface to bind water molecules between skin cells, creating a reservoir effect that keeps skin plump from within. High-molecular-weight HA forms a breathable moisture film on the surface, reducing transepidermal water loss throughout the day.
