Review

Results you may expect from using Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules:

  • Light moisturizing. It has a moisturizing rating of 2.2 out of 10.
  • Little anti-wrinkle effect: Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules has an anti-wrinkle rating of 0.9 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.

How moisturizing is it?

Lightly moisturizing: Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules has a moisturizing rating of 2.2 out of 10.

Is it more humectant or occlusive? Purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a moderate humectancy of 4.5 out of 10, primarily due to the high content of Glycerin (est. ≈2.0%).

Tip: Studies suggest that humectants alone do not moisturize the skin. We recommend applying a product with some occlusive ingredients after the use of this one.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Anti-wrinkle efficacy

According to CreamScan analysis, Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules has a minimal anti-wrinkle rating of 0.9 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Glycolic Acid (est. ≈3.0%),
 highly effective in peelings, yet with below-average anti-wrinkle efficacy when used in leave-on skincare products.
 
Among others, Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules also contains 3-O-Ethyl Ascorbic Acid, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of 3-O-Ethyl Ascorbic Acid provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not contribute to the anti-wrinkle rating.
 
Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, could deliver additional anti-wrinkle efficacy through its moisturizing action.

Ingredients explained

Water
Est. %80
Function
Origin
The most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Isopropyl Myristate
Est. %6
Function
Origin
A fast-spreading, cost-effective, non-greasy emollient that is typically used for lubrication, spreadability, or to remove “tackiness” from a product. Isopropyl Myristate is listed as a common comedogenic ingredient by acne.org.
Oleyl Alcohol
Est. %4
Function
Origin
Description is coming soon
Glycolic Acid
Est. %3
Function
Origin

The second most used AHA (after lactic acid) known for its potent exfoliating and smoothing effects. It increases skin cell turnover, which is beneficial for treating acne. When used in peels, glycolic acid has confirmed anti-wrinkle efficacy, though it is less effective in leave-on products like creams and serums.

Glycerin
Est. %2
Function
Origin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Pentylene Glycol
Est. %1.5
Function
Origin

A naturally or synthetically derived preservative that exhibits effective antifungal and antibacterial traits. It also acts as a booster for more traditional preservatives. Pentylene glycol can also serve as a moisturizing humectant and solvent.

Alcohol Denat.
Est. %1.3
Function
Origin

Denatured alcohol is ethanol that contains additives that make it unsafe to consume. It is mainly used as a solvent and an antimicrobial agent. A major drawback to alcohol denat. is that it dries out the skin.

Lactic Acid
Est. %1
Function
Origin
The most popular AHA in skincare and less irritating than glycolic acid. It can be naturally found in sour milk. It is a humectant moisturizing, pH stabilizing, and gently exfoliating ingredient, able to soften dry, cracked, and peeling skin.
Sodium Hydroxide
Est. %0.3
Function
Origin

An ingredient that is able to bring the pH of a product up, thereby making it less harsh on the skin.

3-O-Ethyl Ascorbic Acid
Est. %0.3
Function
Origin
A derivative of vitamin C. Its stability in skincare formulations is better than ascorbic acid’s, although clinical studies are yet to indicate whether it has the same collagen-boosting benefits.
Phytic Acid
Est. %0.3
Function
Origin
Phytic acid is found in rice and is seen as a cousin of alpha-hydroxy acids. As a chelator, it can bind to certain metals that may cause discoloration in products or reduce the efficacy of other ingredients.
Bisabolol
Est. %0.3
Function
Origin
An anti-inflammatory compound found naturally in German chamomile essential oil. It has a pleasant, sweet, and floral scent. Bisabolol also has soothing and anti-inflammatory properties but can cause an allergic reaction in more sensitive individuals.
Tocopheryl Acetate
Est. %0.3
Function
Origin

An antioxidant derivative of tocopherol (vitamin E). It helps to protect cells from free radicals and UV damage through the conversion to active vitamin E in the skin. It is more stable than tocopherol.

Lavandula Angustifolia (Lavender) Oil
Est. %0.3
Function
Origin
An essential oil derived from common, or true, lavender. It is used in skincare for its lovely, calming scent. Like all essential oils, however, it may cause a contact skin allergy in more sensitive individuals.
Linalool
Est. %0.3
Function
Origin
A fragrant, volatile compound naturally present in many essential oils. It has a pleasant scent and is often used in skincare products as a fragrance. People with sensitive skin should try to avoid it, or at least do a patch test before using it.
Farnesol
Est. %0.3
Function
Origin
A fragrant, liquid alcohol that is naturally found in many essential oils. It has a soft, sweet, floral scent. People with sensitive skin should try to avoid it, or at least do a patch test before using it.
