Kiehl's Vital Skin-Strengthening Super Serum

Our fast-absorbing serum strengthens skin from within its deep surface layer* to help correct and protect against signs of aging, including those accelerated by stressors. Formulated with 11kDa Hyaluronic Acid, our smallest molecular size for efficiency, our lightweight, bio-compatible “super serum” replenishes and fortifies the skin barrier for improved resilience. With an Adaptogenic Herbal Complex, our formula visibly renews skin by stimulating the essential resurfacing of surface skin cells, including improving the look of fine lines and radiance. Skin has a healthy-looking glow, smooth texture and supple bouncy feel. *Within the stratum corneum layer
