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. Our 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

Our Adaptogenic Herbal Complex is a proprietary blend of adaptogens — Red Ginseng Root, Holy Basil and Schisandra Berry — traditionally used in Traditional Chinese, Korean and Ayurvedic Medicine. Within our formula, these adaptogens work synergistically to defend skin from stressors while renewing and resurfacing skin’s texture for a smooth, radiant appearance.

  • Red Ginseng Root – Known for providing cell energy and stimulating the resurfacing of skin cells
  • Holy Basil – Known for its skin soothing properties, which help to reduce the effects of skin stressors
  • Schisandra Berry – Rich in antioxidants, known for reinforcing skin resiliency and elasticity

How to Apply

Every day your skin comes into contact with stressors that can all lead to premature skin aging. UV exposure, pollution and extreme temperatures along with tobacco, stress, lack of sleep and nutrition can all have negative impacts on your skin and cause dullness, dryness, dehydration, fine lines and other signs of aging. Our formula is clinically demonstrated* to double skin’s strength** to help protect against the stress-related signs of aging to help keep your skin more radiant and healthy-looking.

Frequently Asked Questions

What are some common skin stressors and how do they accelerate signs of aging?

Skin faces constant assault from environmental stressors. These stressors appear in many forms that are both external and internal, and not always visible. Pollution, smoke and sun exposure are ever present in the urban environments many of us live in, along with external and internal stress - which may be short- or long-lived. The effects can leave skin looking dull with transient surface textural changes. The constant assault is an important emerging external aging factor and requires attention similar to that of UV-induced damage.

What can happen to skin stressed from its environment?

Environmentally stressed skin can appear in different ways depending on the source of stress, yet share a common cause of damage – free radical damage and a compromised skin barrier. For example, a dry environment can dehydrate skin leaving it lacking moisture and dull looking. Exposure to a poorly ventilated environment, such as a subway station, can increase oxidative break down of skin lipids sebum at the skin surface because of exposure to pollutants from train exhaust. That is why we tested Vital Skin-Strengthening Super Serum in polluted cities in Europe and Asia to help support its skin strengthening, anti-oxidant properties, and its stress fighting benefits in challenging urban environments.

What are adaptogens?

In traditional medicine practices across different cultures, adaptogenic botanicals have been used to treat fatigue and stress, including skin conditions. These plants produce naturally occurring molecules called adaptogens, which can help the skin defend itself against stressors and to maintain its health and balance. When the skin is in a normal or unchallenged state, adaptogens remain inactive and do not interfere with normal skin function. However, when skin is challenged by stressors, adaptogens activate and work to fight stressors, helping return skin to a healthy and youthful state.

How does this hyaluronic acid serum make skin feel stronger?

Super Serum helps skin to feel stronger by improving our four defined clinical dimensions of skin strength. Through our clinical research and experience evaluating skin, we have observed skin that is vulnerable can be less resilient and bouncy, with a compromised barrier. Based on these observations, we defined stronger feeling skin to be supple, resilient, plump, and having a strong skin barrier; and tested Super Serum with a specially developed clinical index based on a composite, average score of three clinically graded parameters; plumpness, suppleness and resilience. The visible skin benefits of Super Serum, with 11 kDa Hyaluronic Acid and our adaptogenic herbal complex, are driven by our biocompatible formula and its strengthening hydrating action and antioxidant properties.

How long does it take for this hyaluronic acid serum to work?

Using Super Serum, upon immediate application skin will feel smoother and supple. Over time, skin will feel more resilient to daily life stressors and look healthier and youthful as fine lines, texture, and radiance visibly improve. In fact, after two weeks of use, consumers reported that their skin felt firmer and more resilient to daily life stressors.

Where and how can I incorporate this hyualruonic acid serum into my skincare routine?

Considering the lightweight and easily absorbed nature of Super Serum, it can be incorporated into your morning and nighttime routines. Use after cleansing and toning skin and before your favorite moisturizer. For days when your skin needs a little more care, layer it underneath your serum as a pre-serum before applying moisturizer.

Rated 4 out of 5 by from Kiehl Away Bad Skin Prior to this product testing I had never tried Kiehls before. I was really pleased with the way it went on my face. It felt light and didnt cause any breakouts. If I could choose another scent, I would. Otherwise it was a good product that help my skin feel moisturized and fresh.

Rated 4 out of 5 by from Love it! This serum is SO hydrating and makes your skin look a bit brighter. I would usually put it on at night because mixed with my daytime moisturizer, my face would get a tiny but oily. Thats my only complaint about this product, other than that its great! Lightweight, smells good, and effective.

Rated 5 out of 5 by from serum It is a good serum, I have used it for more than a month and I can recommend it. The only thing I would ask to change is the smell.

Rated 4 out of 5 by from skin so smooth As a disclaimer I received this product for free to test and review. When opening the product for the first time the smell was very strong. I was nervous when applying it to my face that it would leave my skin kinda oily, but quickly dried and did not feel oily or heavy at all. The results were great after a few weeks of use I saw my skin get stronger and a lot smoother.

Rated 4 out of 5 by from good not great Since I dont have fine lines or wrinkles to address right now, I cant attest to the serums claims on those issues. I enjoyed this serum because it does hydrate and retain moisture. Love the scent. Texture is nice, non-sticky, absorbs quickly. Im not sold on the price. I have tried and loved other affordable serums!

Can you compare this product to the vitamin C serum?

Asked by: Bizz
The Kiehl's customer service rep failed to answer the question. Comparing the main active ingredient is something that anyone could look up. But I want to know what is the difference in using the products? As in for what benefits do each product have? Because I currently use the VC serum am I am considering switching to this product; however, I do not know what the benefits of this are over the other to make such a switch. In other words, tell me what the actually differences are in the benefits of using such a product. Don't just tell me the ingredients
