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

    I wanted to love this, because I love most kiehl’s products, but I did not like this one. It made my face break out.

    My go-to serum
    Aug 21, 2021

    This is one of my favourite serums (the other being the new retinol serum), which fits in well with my no-fuss skincare regime. It has a perfectly measured dose, is light and absorbed quickly. My skin certainly feels smoother and more supple, compared with days when I skip straight to a moisturiser. I find it doesn’t really have any smell and it isn’t irritating. This is a holy grail serum for me that I always repurchase.
