Minimally formulated with only 7 ingredients, our concentrated 1.5% Hyaluronic Acid serum has a fast-absorbing texture that allows actives to be rapidly delivered into the skin, leaving it feeling plumper, replenished, and hydrated.

Expert Advice

“We wanted to deliver known skin actives, such as Niacinamide, Glycolic Acid and Hyaluronic Acid in their pure form in simple formulations without too many ingredients to deliver efficacy, layer well into a skin regimen, such as with Kiehl’s Ultra Facial Cleanser and Ultra Facial Cream and allow users to customize their skin care according to their needs. The simplified formulas ensure the ingredients absorb fully into the skin. Topically applied, Hyaluronic Acid in our Ultra Pure High-Potency Serum 1.5% Hyaluronic Acid helps boost skin’s hydration, softness and reduces the appearance of dry, fine lines.”
