Key Benefits of The INKEY List 15% Vitamin C and EGF Brightening Serum

 
These are the key benefits you can expect from using The INKEY List 15% Vitamin C and EGF Brightening Serum:
 

🔵 Slight Moisturizing When Used Alone

According to CreamScan analysis, The INKEY List 15% Vitamin C and EGF Brightening Serum is slightly moisturizing, with a moisturizing rating of 0.3 out of 10.

Is it more humectant or occlusive? This product is purely humectant, but with a low Humectancy of 0.6 out of 10. It has zero Occlusivity as we didn't find any occlusive ingredients on the ingredient list.

This type of product provides relatively light moisturizing on its own but can contribute to overall moisturizing efficacy when used as part of a skincare routine, alongside another moisturizer.

❗️ 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.

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

🍀 Rich in Skin-Protecting Antioxidants

We estimate that The INKEY List 15% Vitamin C and EGF Brightening Serum is rich (> 3%) in antioxidants, specifically Ascorbyl Glucoside (est. ≈15.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

📌 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: The INKEY List 15% Vitamin C and EGF Brightening Serum

 
CreamScan AI identified a few things to consider before adding The INKEY List 15% Vitamin C and EGF Brightening Serum to your skincare routine:
 

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing The INKEY List 15% Vitamin C and EGF Brightening Serum is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Ascorbyl Glucoside and Oligopeptide-1, 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.
Ascorbyl Glucoside
Est. %15
Function
Origin
Ascorbyl GlucosideA derivative of vitamin C. It is more stable and less irritating than ascorbic acid. There are unfortunately no clinical studies on ascorbyl glucoside’s anti-pigment or anti-acne efficacy alone.
Sodium Hydroxide
Est. %4
Function
Origin
Sodium Hydroxide

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

PEG-40 Hydrogenated Castor Oil
Est. %3
Function
Origin
PEG-40 Hydrogenated Castor OilA castor oil-derived ingredient often used to incorporate small amounts of oil (such as a fragrance) into a water-based product. PEG-4 HCO is a gold-standard solubilizer and can be used in low amounts due to its ability to solubilize things so well.
Phenoxyethanol
Est. %1
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.
Benzyl Alcohol
Est. %0.3
Function
Origin
Benzyl Alcohol

A multifunctional ingredient that is supplied as a clear, colorless liquid. Its main function is as a flavoring agent and fragrance. It also acts as a broad-spectrum preservative, solvent, and viscosity-controlling agent that thins the product.

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.

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.
Sodium Metabisulfite
Est. %0.3
Function
Origin
Sodium MetabisulfiteA preservative that is especially effective at preventing fungus and mold growth. It is normally combined with a strong bactericidal preservative in order to achieve broad-spectrum protection. Sodium metabisulfite is also used as an antioxidant.
Dehydroacetic Acid
Est. %0.3
Function
Origin
Dehydroacetic AcidA globally approved preservative ingredient. It is a powerful fungicide and a moderate bactericide, which makes it a broad-spectrum preservative. Because it is mildly effective against bacteria, it is often paired with stronger bactericides.
Phytic Acid
Est. %0.3
Function
Origin
Phytic AcidPhytic 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.
Oligopeptide-1
Est. %0.3

Origin
Oligopeptide-1
