product details

A hyaluronic acid serum with an adaptogenic herbal complex that helps boost radiance, protect against skin stressors and visibly prevent signs of aging.

  • SKIN TYPES:
  • Normal, dry, oily, combination, sensitive
  • WHAT IT DOES:
  • Strengthens skin and helps defend against skin-aging stressors, such as UV exposure, pollution and extreme temperatures along with tobacco, stress, lack of sleep and nutrition, which can cause dullness, dehydration, fine lines and other signs of aging
  • KEY INGREDIENTS:
  • 11kDa Hyaluronic Acid:
  • Hyaluronic acid is known to help smooth and plump fine lines and is commonly used in skincare products to maintain moisture levels to boost hydration and visibly refine skin's texture
  • Kiehl's smallest molecular size of hyaluronic acid, 11kDa, penetrates to fortify skin within its deepest surface layers*
  • By delivering hydration to skin's most vulnerable layer, 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 Chinese, Korean and Ayurvedic medicine
  • Within Kiehl's formula, the adaptogens work synergistically to help defend skin from stressors while renewing and resurfacing skin's texture for a smooth, radiant appearance
  • HOW TO USE:
  • Apply onto cleansed face and neck, morning and night, then apply a daily moisturizer; it can also be used under another serum
  • Avoid contact with eyes; if contact occurs, rinse thoroughly with water
  • Pair with Clearly Corrective Dark Spot Solution, Ultra Facial Cream
  • RESULTS:
  • Clinically demonstrated* to double skin's strength** and help visibly reduce fine lines, smooth texture and boost radiance for a healthy-looking glow
  • Clinically demonstrated to boost radiance by 29% and improve resilience by 38% for glowing, healthy-looking skin*
  • Clinically demonstrated to visibly reduce fine lines by 27%*
  • *Based on a 4-week clinical study on 58 subjects tested in urban and polluted environments
  • **Based on Skin Strength Index = Composite average score of skin suppleness, plumpness and resiliency

    Don't get the hype
    Aug 18, 2021

    I love how lightweight it is under other moisturizer, but don't see much difference and the scent is not great at all. Just not worth the money.

    Powerful serum to enhance skin appearance
    Jun 23, 2021

    [This review was collected as part of a promotion.] This serum was very effective for me, in regaining skin elasticity an overall health. I have a mixed skin type and I don’t have any negative reactions to it. It’s light on the skin and get’s absorbed very fast.

    Break outs
    Jun 07, 2021

    I've tried using this product on two different occasions, both times my skin breaks out. Has anyone else experienced this? Does it stop over continuous use? I use it after toner & before other serums then moisturizer. Any advice? Thx

    Not really
    May 05, 2021

    Here’s my honest review I have been using it for 2 mths now mostly morning and night. But if I forget in the AM which is rare always at bedtime. I have not seen any great improvement that I would buy this expensive product. I have the bunny lines between my eyes but not deep ones on the lighter side I do have dry skin and when I have crows feet lined but only when I smile. It seems to work well fir some but definitely not me.

    Winning combo!
    May 05, 2021

    I’ve been using this serum (VSSHASS) since last year and switched to the newer formulation of the Super Multicorrective Cream added several months later. I’m really pleased with results of this combo! My skin seems to tighten a bit after applying the serum which goes on well and is absorbed quickly. I then apply a small amount of the moisturizer which I’ve warmed between my fingertips. All the smile wrinkles have softened up nicely!
