Key Benefits of Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules

 
These are the key benefits you can expect from using Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules:
 

🔵 Lightweight Purely Humectant Moisturizer Suitable for Oily Skin

According to CreamScan analysis, Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules is lightly moisturizing, with 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%).

This product, when used alone as a moisturizer, can provide light humectant hydration in a fast-absorbing formula without any occlusive ingredients. This could work for people with oily skin who need a basic level of hydration.

❗️ Certain studies suggest that humectants alone may not effectively moisturize the skin. If you use this product as your only moisturizer, we recommend following it with one that contains at least some occlusive ingredients.

💧 A Humectant Add-on for Any Skincare Routine

But it’s not limited to oily skin - since it contains a moderate amount of humectants, such a humectant add-on will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer.

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

🟣 Slight Anti-Wrinkle Efficacy

According to CreamScan analysis, Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules has a slight anti-wrinkle rating of 0.9 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Glycolic Acid (est. ≈3.0%),
 a highly effective ingredient in peelings but with moderate anti-wrinkle efficacy in leave-on skincare products, as supported by a single clinical study. This study, involving 72 participants (Thibault et al.), demonstrated that a lotion with 5% GA reduced the fine wrinkling score by 6% after 34 days of use, compared to a vehicle (the same formulation without GA).
 
Among others, Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules also contains 3-O-Ethyl Ascorbic Acid, an ingredient often 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.
 
While this does not categorically rule out the possibility that 3-O-Ethyl Ascorbic Acid may reduce wrinkles, its efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.
 
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, can deliver some additional anti-wrinkle effects through its moisturizing action.
 

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Things to Be Aware Of: Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules

 
CreamScan AI identified a few things to consider before adding Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules to your skincare routine:
 

⚠️ May Increase Skin Photosensitivity Due to Glycolic Acid

This product contains glycolic acid, a popular AHA known for its ability to exfoliate and brighten the skin. Its action works by removing dead skin cells, revealing new, more delicate skin that is particularly vulnerable to sun damage.

As a result, using products with glycolic acid, regardless of concentration, may increase the skin's sensitivity, making it more prone to sunburn or irritation when exposed to UV rays.

To counteract this increased sun sensitivity, apply a broad-spectrum sunscreen with at least SPF 30 daily to protect your skin during glycolic acid treatment.

❗️Please always check the manufacturer's instructions for using the product, either on their website or product label.

⚠️ If It’s Your Only Moisturizer, It Needs to Be Paired with Some Occlusives

While humectants are highly effective at attracting water to the skin, studies (J. N. Kraft, C. W. Lynde) suggest they may not be efficient when used alone.

One major drawback of purely humectant moisturization is that the water attracted by humectants to the upper layers of the skin can evaporate completely into the environment through transepidermal water loss (TEWL). Adding occlusive ingredients helps seal this moisture into the skin and prevent further water loss.

If you’re using Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules as your only moisturizer, consider pairing it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones. These work alongside humectants to create a protective barrier, locking in hydration and ensuring longer-lasting moisturization. The amount of occlusive needed depends on your skin type - the drier the skin, the more occlusives it requires.

If this product is used not as a standalone moisturizer but as part of your skincare routine, such as a toner or serum, it should be applied before your main moisturizer (unless it's a sunscreen), which will provide the necessary occlusivity on top of it.

Pros & Cons of Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules

Summary: Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules

 
Based on the ingredient list analysis, CreamScan AI suggests that Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules
, when used alone, provides lightweight, moderate humectant moisturizing, making it suitable for oily skin. As part of a moisturizing routine, it offers a subtle humectant enhancement, beneficial for all skin types.
 
Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules contains ingredients with proven evidence of anti-wrinkle efficacy that may offer a slight anti-wrinkle effect. As a result, you can expect a positive, though relatively minimal, impact on wrinkles.
 
 
That said, there are some things about Kiehl's Clearly Corrective Accelerated Clarity Renewing Ampoules worth noting.
 
Looking at its moisturizing profile, we found that it doesn’t contain any occlusive ingredients, potentially allowing the moisture attracted to the skin by humectants to evaporate. Therefore, if it’s used as the only moisturizer in a routine, it’s recommended to pair it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones.
 
This product contains glycolic acid, a popular AHA known for its ability to exfoliate and brighten the skin. However, glycolic acid - regardless of concentration - can increase skin sensitivity, making it more prone to sunburn or irritation when exposed to UV rays. Therefore, it’s recommended to use a broad-spectrum sunscreen with at least SPF 30 during glycolic acid treatment.
