Key Benefits of Kiehl's Fast Release Wrinkle-Reducing 0.3% Retinol Night Serum

 
These are the key benefits you can expect from using Kiehl's Fast Release Wrinkle-Reducing 0.3% Retinol Night Serum:
 

Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, Kiehl's Fast Release Wrinkle-Reducing 0.3% Retinol Night Serum is quite moisturizing, with a moisturizing rating of 5.2 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.3 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%), Propanediol (est. ≈4.0%) and Butylene Glycol (est. ≈3.0%).

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.

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

Significant Anti-Wrinkle Efficacy

According to CreamScan analysis, Kiehl's Fast Release Wrinkle-Reducing 0.3% Retinol Night Serum has a high anti-wrinkle rating of 7.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Retinol (est. ≈0.3%), 
 the most effective non-prescription anti-wrinkle ingredient. Numerous clinical studies have shown its positive effects at concentrations as low as 0.1%. A study with 36 participants (Kafi et al.) confirmed that a lotion containing 0.4% retinol reduced wrinkle severity by 21% after 24 weeks of use, compared to the same formulation without retinol (vehicle).
 
Among others, Kiehl's Fast Release Wrinkle-Reducing 0.3% Retinol Night Serum also contains Adenosine, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Adenosine provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not contribute to the anti-wrinkle rating.
 

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

Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: Kiehl's Fast Release Wrinkle-Reducing 0.3% Retinol Night Serum

 
CreamScan AI identified a few things to consider before adding Kiehl's Fast Release Wrinkle-Reducing 0.3% Retinol Night Serum to your skincare routine:
 

May Increase Skin Photosensitivity Due to Retinol

This product contains retinol, which offers powerful anti-wrinkle benefits. The mechanism behind retinol’s action is boosting cell turnover. This process exposes new, more delicate skin, making it more vulnerable to sun damage.

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

To protect the skin, dermatologists recommend applying a broad-spectrum sunscreen with at least SPF 30 throughout the duration of retinol treatment, along with avoiding direct sun exposure. Retinol should be used at night, as it is sensitive to sunlight and can lose its potency when exposed to UV rays.

Please always check the manufacturer's instructions for using the retinol-containing products, either on their website or product label.

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.
Glycerin
Est. %6
Function
Origin
Glycerin

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

Propanediol
Est. %4
Function
Origin
PropanediolAn excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.
Butylene Glycol
Est. %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.

Glycereth-26
Est. %2
Function
Origin
Glycereth-26

A glycerin-based ingredient with humectant moisturizing properties. It is an excellent emulsifier and thickener.

Panthenol
Est. %1.5
Function
Origin
PanthenolA popular soothing and moisturizing derivative of vitamin B5. Panthenol is particularly beneficial for dry, flaking, burned, or damaged skin. It is used to alleviate the symptoms of a rash, dermatitis, eczema, chapped lips, and sunburn.
1,2-Hexanediol
Est. %1.3
Function
Origin
1,2-HexanediolA multi-functional formula helper. It is a well-studied preservtive against bacteria and can help pigments and fragrances disperse evenly in a formula.
Polyglycerin-3

Polyglycerin-3
C12-14 Pareth-12
Est. %0.3
Function
Origin
C12-14 Pareth-12
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.
Caprylyl Glycol
Est. %0.3
Function
Origin
Caprylyl GlycolAn emollient that improves product spreadability and offers a silky feel on the skin. It also acts as a preservative booster that improves the efficacy of other preservatives. According to the manufacturer, it is also a humectant moisturizer.
Ammonium Acryloyldimethyltaurate/VP Copolymer
Est. %0.3
Function
Origin
Ammonium Acryloyldimethyltaurate/VP CopolymerA polymeric ingredient that creates lightweight and refreshing gel textures. It also works as a viscosity controlling agent.
Betaine
Est. %0.3
Function
Origin
BetaineAn ingredient derived from the sucrose in sugar beets. It has a negative chemical charge and a positive chemical charge on the same molecule. This allows betaine to be hygroscopic or humectant and thus provide moisturization by drawing water to the skin.
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.
Ethylhexylglycerin
Est. %0.3
Function
Origin
EthylhexylglycerinA preservative booster derived from glycerin. It is commonly paired with other preservatives to improve their efficacy. Ethylhexylglycerin is also a humectant due to its chemical base of glycerin.
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.

Carbomer
Est. %0.3
Function
Origin
CarbomerA synthetic ingredient with the ability to gel water. When used in emulsions, such as lotions and creams, carbomer can also act as an emulsion stabilizer.
Glyceryl Acrylate/Acrylic Acid Copolymer
Est. %0.3
Function
Origin
Glyceryl Acrylate/Acrylic Acid CopolymerA synthetic humectant moisturizer often paired with glycerin. It also functions as a viscosity-controlling agent that creates gel-like formulas with thicker textures.
Tromethamine
Est. %0.3
Function
Origin
TromethamineAn ingredient based on amino acids that is commonly used as a pH adjuster. It has a high pH, which means that it is basic (alkaline), so adding tromethamine to a skincare product will increase its overall pH level.
Glycereth-25 PCA Isostearate
