Hyaluronic Acid
INCI: Sodium Hyaluronate
Korean: 히알루론산
humectant, hydration
A powerful humectant that holds up to 1000x its weight in water. K-beauty products often use multiple molecular weights (high, medium, low) for surface-to-deep hydration. Low molecular weight penetrates deeper; high molecular weight sits on the surface for a plumping effect.
