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.
Elevate Your Skincare Routine Today
Whether you're targeting early signs of aging or looking to maintain your skin's natural radiance, this 3.4 oz / 100 ml bottle gives you a generous supply of one of Kiehl's most iconic formulas. Apply a few drops to cleansed skin each morning before moisturizer and SPF for best results. Ships fast from the US — so your skin doesn't have to wait. Add it to your routine and feel the difference that decades of skincare expertise can make.
