SkinCeuticals H.A. Intensifier

Hyaluronic acid is a powerful natural humectant which helps regulate moisture levels in skin. This essential molecule however has a short lifecycle in skin, with 30%-50% degrading every 24 hours. With age, the skin experiences a gradual decline in hyaluronic acid levels. Production starts to decrease in the 20s and accelerates in the 40s. The combination of decline and this rapid degradation of hyaluronic acid contribute to signs of aging, including decreased firmness, less facial plumpness, and rough texture. While hyaluronic acid is a powerful hydrator, its molecular size renders it too large for optimal skin absorption. H.A. Intensifier uniquely combines surface-hydrating hyaluronic acid with 10% proxylane and an optimal concentration of licorice and purple rice extracts to support skin’s hyaluronic acid levels.
