Vital Skin-Strengthening Super Serum

Kiehl's NEW skin-strengthening serum helps protect against skin-aging stressors and visibly corrects signs of aging.

WHAT IT IS?
Skin-strengthening serum penetrates skin up to 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.

*Based on a clinical study of 25 panelists measuring the penetration of the full formula via tape stripping.

**Stratum corneum layers.

WHAT IT'S GOOD FOR?

Strengthens skin from within its deep surface layers
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

KEY INGREDIENTS:

11kDa HYALURONIC ACID
Kiehl's smallest molecular size of Hyaluronic Acid, this micronized ingredient penetrates skin to deliver skin-strengthening hydration. 11kDa Hyaluronic Acid helps better retain moisture for improved resiliency, suppleness and bounce.

ADAPTOGENIC HERBAL COMPLEX
Adaptogenic Herbal Complex is a proprietary blend of adaptogens — Red Ginseng Root, Holy Basil and Schisandra Berry — traditionally used in Traditional Chinese, Korean and Ayurvedic Medicine. Within our formula, these adaptogens work synergistically to defend skin from stressors while renewing and resurfacing skin’s texture for a smooth, radiant appearance.
