Kiehl's Vital Skin-Strengthening Super Serum 100ml

What It Is: Our skin-strengthening serum penetrates skin 8 surface layers deep* to help correct signs of aging through visibly diminishing fine lines and reviving tired-looking, dull skin, which can be caused by skin-aging stressors. Formulated with 11kDa Hyaluronic Acid — our smallest form of Hyaluronic Acid — and a proprietary Adaptogenic Herbal Complex, our potent "super serum" deeply penetrates skin’s surface layers** and neutralizes skin-aging stressors to visibly renew skin. What It’s Good For: • Strengthens skin from within its deepest surface layer • Protects against stressors including sun exposure, pollution, stress, lack of sleep, diet and temperature that can lead to early signs of aging • Visibly reduces fine lines, improves resilience and boosts radiance for glowing, healthy-looking skin • Absorbs easily with a lightweight texture • For all skin types, including sensitive skin *Based on a clinical study of 25 panelists measuring the penetration of the full formula via tape stripping. **Stratum corneum layers.
