Key Benefits of Kiehl's Clearly Corrective Brightening & Smoothing Moisture Treatment

 
These are the key benefits you can expect from using Kiehl's Clearly Corrective Brightening & Smoothing Moisture Treatment:
 

🔵🔵 Perfect Moisturizer for Normal to Dry Skin with a Balanced Texture, Neither Too Light nor Too Heavy

According to CreamScan analysis, Kiehl's Clearly Corrective Brightening & Smoothing Moisture Treatment is highly moisturizing, with a moisturizing rating of 7.3 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Propylene Glycol (est. ≈6.0%) and Glycerin (est. ≈4.0%), and a moderate occlusivity of 4.6 out of 10, mainly due to the high content of Dimethicone (est. ≈9.0%).

This type of moisturizer is ideal for people with normal skin who want maximum hydration in a formula with a balanced texture - neither too light nor too heavy. It combines a very high concentration of humectants with a moderate amount of occlusive ingredients to deliver effective dual-action moisturizing for normal skin.

This product may also be a good choice for people with normal to dry skin for daily hydration.

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 Brightening & Smoothing Moisture Treatment has a slight anti-wrinkle rating of 0.1 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Glycolic Acid (est. ≈0.3%),
 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 Brightening & Smoothing Moisture Treatment also contains contains 3-O-Ethyl Ascorbic Acid and Adenosine, two ingredients often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards.
 
While this does not categorically rule out the possibility that these ingredients may reduce wrinkles, their 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, these ingredients do 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 Brightening & Smoothing Moisture Treatment

 
CreamScan AI identified a few things to consider before adding Kiehl's Clearly Corrective Brightening & Smoothing Moisture Treatment 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.

Ingredients explained

Water
Est. %65
Function
Origin
WaterThe 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.
Dimethicone
Est. %9
Function
Origin
DimethiconeThe most common silicone in skincare. It forms a silky, smooth film on the skin’s surface and can help to prevent water loss. It also aids in wound healing and can treat and soften scars. Dimethicone is considered to be very safe for use.
Propylene Glycol
Est. %6
Function
Origin
Propylene GlycolA clear, thick, odorless liquid of synthetic origin. Its main function is to stabilize cosmetic products exposed to varying temperatures. It is also a moderately strong humectant with similar properties to glycerin.
Glycerin
Est. %4
Function
Origin
Glycerin

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

Alcohol Denat.
Est. %3
Function
Origin
Alcohol Denat.

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.

Hydroxypropyl Tetrahydropyrantriol
Est. %2.5
Function
Origin
Hydroxypropyl Tetrahydropyrantriol
Butylene Glycol
Est. %2
Function
Origin
Butylene Glycol

A clear, colorless liquid humectant that draws moisture to the skin. The humectancy of butylene glycol, owed to its two hydroxyl groups, is quite considerable, although not as powerful as glycerin, which contains three hydroxyl groups.

Dimethicone/PEG-10/15 Crosspolymer
Est. %1.5
Function
Origin
Dimethicone/PEG-10/15 CrosspolymerA self-emulsifying surfactant, which means that it can help facilitate the formation of water-in-silicone emulsions. This results in lightweight formulas with a soft finish. It can also act as a film-former and thickener.
3-O-Ethyl Ascorbic Acid
Est. %1.3
Function
Origin
3-O-Ethyl Ascorbic AcidA 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.
Paeonia Suffruticosa Root Extract
Est. %1
Function
Origin
Paeonia Suffruticosa Root ExtractA soothing extract obtained from a hybrid species of tree peony that contains various active compounds such as astringent tannins, terpenes, and paeonols.
Potassium Hydroxide
Est. %0.3
Function
Origin
Potassium HydroxideA very alkaline ingredient, meaning that it has a high pH. Potassium hydroxide is therefore useful in bringing a low pH in a cosmetic product up to a more neutral, skin-safe level.
Lavandula Angustifolia (Lavender) Oil
Est. %0.3
Function
Origin
Lavandula Angustifolia (Lavender) OilAn 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.
Glycolic Acid
Est. %0.3
Function
Origin
Glycolic Acid

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.

Sodium Citrate
Est. %0.3
Function
Origin
Sodium CitrateA salt of citric acid that has a salty and tart flavor and is used as a fragrance. It is mildly basic, meaning that its addition to a skincare product can adjust the pH upward.
Silica
Est. %0.3
Function
Origin
SilicaA widely used cosmetic ingredient with the same chemical composition as the sand found on beaches. A common function of silica is its ability to control viscosity. In certain chemical forms, it can effectively thicken cream-style products.
Adenosine
Est. %0.3
Function
Origin
Adenosine

A key molecule responsible for energy transportation, signaling, and enzyme activity. Adenosine is a popular anti-wrinkle ingredient, however, the key study about its anti-wrinkle efficacy (1) does not meet CreamScan Research Evaluation Standards as it is not double-blind.

Magnesium Sulfate
Est. %0.3
Function
Origin
Magnesium SulfateA naturally occurring mineral that is commonly used in skincare products as a bulking agent. It helps to control the viscosity of products by making them thicker.
Disodium EDTA
Est. %0.3
Function
Origin
Disodium EDTAA synthetic chelator that helps to maintain the look and smell of a product by 'locking up' troublesome metal ions.
Dipropylene Glycol
Est. %0.3
Function
Origin
Dipropylene GlycolA clear, colorless liquid that has several uses. One of its main functions is as a solvent. Dipropylene glycol is also used to reduce the thickness of skincare products.
Citric Acid
Est. %0.3
Function
Origin
Citric AcidA gently exfoliating AHA that helps to remove the top layer of dead skin cells. In comparison to other AHAs, citric acid has been shown to be one of the least effective. It is also very commonly used as a stabilizing and pH-controlling agent.
Citrus Aurantium Tachibana Peel Extract
Est. %0.3
Function
Origin
Citrus Aurantium Tachibana Peel Extract
Tocopherol
Est. %0.3
Function
Origin
Tocopherol

Simply another name for vitamin E. Tocopherol is a fantastic ingredient and especially beneficial for dry and inflamed skin. It has occlusive moisturizing, emollient, antioxidant, and photoprotective properties.

Tocopheryl Acetate
Est. %0.3
Function
Origin
Tocopheryl Acetate

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.

Salicylic Acid
Est. %0.3
Function
Origin
Salicylic AcidThis effective peeling and anti-inflammatory BHA is used as an anti-acne agent and works by breaking down the junctions between dead skin cells. This results in the peeling of dead skin and the unclogging of pores.
Phenoxyethanol
Est. %0.3
Function
Origin
PhenoxyethanolThe most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
Linalool
Est. %0.3
Function
Origin

Function
Origin
Limonene

One of the most used fragrances in skincare products. It is produced from the peels of citrus fruits and has a fresh, pleasant, citrusy smell. People who are sensitive to citrus should try to avoid it, or at least do a patch test before using it.
