Key Benefits of Kiehl's Clearly Corrective Dark Spot Solution

 
These are the key benefits you can expect from using Kiehl's Clearly Corrective Dark Spot Solution:
 

🔵 Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, Kiehl's Clearly Corrective Dark Spot Solution is quite moisturizing, with a moisturizing rating of 5.1 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.2 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Propylene Glycol (est. ≈6.0%), Glycerin (est. ≈4.0%) and PEG/PPG/Polybutylene Glycol-8/5/3 Glycerin (est. ≈2.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, offering significant hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients.

It’s also a great choice for people with normal skin who prefer lightweight moisturizers.

💧 A Humectant Boost for Any Skincare Routine

But it’s not limited to oily skin - such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

Things to Be Aware Of: Kiehl's Clearly Corrective Dark Spot Solution

 
CreamScan AI identified a few things to consider before adding Kiehl's Clearly Corrective Dark Spot Solution to your skincare routine:
 

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Kiehl's Clearly Corrective Dark Spot Solution is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It 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 generate 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 anti-wrinkle effects through its moisturizing action.

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

Ingredients explained

Water
Est. %75
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.
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.

PEG/PPG/Polybutylene Glycol-8/5/3 Glycerin
Est. %2
Function
Origin
PEG/PPG/Polybutylene Glycol-8/5/3 Glycerin
Hydroxypropyl Tetrahydropyrantriol
Est. %1.5
Function
Origin
Hydroxypropyl Tetrahydropyrantriol
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.
PPG-6-Decyltetradeceth-30
Est. %1
Function
Origin
PPG-6-Decyltetradeceth-30
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.
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.
Xanthan Gum
Est. %0.3
Function
Origin
Xanthan GumA natural multi-functional ingredient that originates from fermented sugars. Xanthan gum acts as a viscosity-building agent to thicken skincare products. It is also an excellent stabilizer and works well to hold other ingredients together.
Hydroxyethylcellulose
Est. %0.3
Function
Origin
HydroxyethylcelluloseA naturally-derived thickener that can form clear gel textures without the slimy feeling, unlike some other natural gel-formers.
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.
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.
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.
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.

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.
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.
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.

Linalool
Est. %0.3
Function
Origin
LinaloolA 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.
Butylene Glycol
Est. %0.3
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.

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.

Citrus Aurantium Tachibana Peel Extract
Est. %0.3
Function
Origin
Citrus Aurantium Tachibana Peel Extract
Paeonia Suffruticosa Root Extract
Est. %0.3
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.
