“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. Our Ultra Pure High- Potency Serum 9.8% Glycolic Acid targets skin texture issues helping to smooth skin, improve skin radiance, and minimize the look of pores.”
