The new Vital Skin-Strengthening Super Serum is a fast-absorbing, ultra-light, multi-benefit anti-aging facial serum with 11kDa hyaluronic acid and an adaptogenic herbal complex formulated to strengthen skin from its deepest layers to help combat the signs of aging, including those caused by both external and internal aggressors, helping skin feel more resilient, elastic, and dense for youthful-looking skin in as little as four weeks.
Discover the formula of this new anti-aging facial serum:
11 kDa Hyaluronic Acid: Kiehl's 11 kDa hyaluronic acid is the ideal size, allowing it to deliver targeted, intense, and rapid action to the skin's surface layers. Its formula has been scientifically tested to strengthen the upper layers of the skin, which are most vulnerable to external aggressors, providing fortifying hydration.
ADAPTOGENIC HERBAL COMPLEX: Adaptogenic herbs have always been highly valued in traditional medicine for treating fatigue and stress. Kiehl's formula with adaptogenic herbs helps plump and strengthen skin to visibly improve its texture and resilience. Kiehl's potent Adaptogenic Herbal Complex contains schisandra berry, holy basil, and red ginseng root. -HOLY BASIL Rich in ursolic and rosmarinic acids, our formula's holy basil helps neutralize skin-damaging free radicals and revitalizes the appearance of the skin, helping to reduce the visible effects of stressors. -RED GINSENG ROOT stimulates essential skin cell renewal. -SCHISANDRA BERRY helps improve skin's resilience and elasticity and is an antioxidant. From the first application of this anti-aging facial serum, Kiehl's "Super Serum," your skin will feel smoother and, over time, more resilient to everyday stressors. Your skin will appear healthier and more youthful as fine lines, texture, radiance, and elasticity visibly improve. The brand's new Super Serum has been clinically proven to:
IMPROVE SKIN BRIGHTNESS BY 29.9%. IMPROVE SKIN SOFTNESS BY 41.7% REDUCE THE APPEARANCE OF EXPRESSION LINES BY 27.2%.

Kiehl's Vital Skin-Strengthening Super Serum can be incorporated into any morning and night skincare routine by simply applying it after cleansing and toning as a pre-treatment for your regular anti-aging facial serum or as a serum to complement your routine.
It took me a while to realize this product was causing a reaction because I tried a new routine recommended by a Kiehl’s sales assistant in Valladolid (El Corte Inglés, Paseo de Zorrilla). My neck turned red and I broke out in hives. I couldn’t sunbathe all summer! El Corte Inglés offered no solution because I didn’t have a receipt, even though they had the product registered in their computer system as a regular customer. You have some very good products, but this has really upset me, and I won’t be a Kiehl’s customer anymore.
