DISCOVER THE BENEFITS OF
KIEHL’S MICRONIZED
11KDA HYALURONIC ACID

VSSS Background

What is Micronized 11kDa hyaluronic acid?

Hyaluronic acid is naturally present in our bodies, and is known for its powerful hydrating ability. It is a humectant which can hold up to 1,000 times its weight in water, acting like a sponge to draw moisture into our skin’s surface layers. In skincare, hyaluronic acid is important for increasing skin’s moisture levels for a healthy skin barrier.
Did you know that the molecular size of our hyaluronic acid makes a difference? Kiehl’s scientists have chosen the appropriate size of hyaluronic acid for each individual formula to create highly effective formulas that are appropriate for all skin types.

11kDa, or “kilodalton”, refers to the size and weight of our hyaluronic acid molecule. Micronized 11kDa hyaluronic acid is the smallest hyaluronic acid molecule in the Kiehl’s portfolio. It is a much smaller molecular size than standard hyaluronic acid, which has a molecular size of 1000kDa, and is just the right size (not too big, not too small) to penetrate deeper into skin for fast delivery.

What are its benefits for the skin?

Our skin is exposed to everyday stressors that accelerate aging, such as UV rays, pollution and lack of sleep. These stressors weaken skin and compromise its ability to defend itself, which results in accelerated signs of aging such as fine lines, wrinkles and dull skin.
*Formula penetration results based on a clinical study of 25 panelists measuring the penetration of the full formula via tape stripping.
Our new Vital Skin-Strengthening Super Serum is formulated with 11kDa hyaluronic acid to penetrate skin up to 8 surface layers deep.

This improves overall skin strength and resilience, which allows skin to better defend itself against the negative effects of skin-aging stressors for supple, bouncy and youthful skin.

The best anti-aging and hyaluronic acid face serums work to correct and protect skin from early signs of aging. The result is strong, healthy skin that is better able to resist the effects of skin-aging stressors before they can cause skin to age. With micronized 11kDa hyaluronic acid and other powerful ingredients, Kiehl’s Vital Skin Strengthening Super Serum offers a multitude of benefits: fine lines are better prevented and reduced, your skin’s youthful radiance is boosted, and improved texture with smooth and supple skin.
