KIEHL'S Powerful Strength Line Reducing Concentrate Hyaluronic 3.4 oz / 100 ml

Visibly Younger Skin, Powered by Pure Vitamin C

Meet the serum that skincare devotees swear by. The KIEHL'S Powerful Strength Line Reducing Concentrate is a clinically proven, high-potency Vitamin C serum formulated with 10.5% pure Vitamin C and Hyaluronic Acid to visibly reduce the appearance of fine lines and wrinkles — while delivering an intense surge of hydration. This is not your average brightening serum. This is a daily ritual that transforms skin from the inside out, leaving it firmer, smoother, and luminously radiant with every use.

A Formula That Works as Hard as You Do

Kiehl's has long been a trusted name in dermatologist-tested skincare, and this concentrate is a testament to that legacy. The potent blend of 10.5% pure Vitamin C works to neutralize free radicals and stimulate collagen production, while Hyaluronic Acid draws moisture deep into the skin's surface for a plumping, line-filling effect. The result? Skin that looks visibly firmer, more even-toned, and refreshed — after just four weeks of consistent use. Suitable for all skin types, including sensitive skin, this serum is your shortcut to a more youthful, glowing complexion.
