Review

Results you may expect from using The INKEY List Alpha Hydroxy Acid Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using The INKEY List Alpha Hydroxy Acid Serum:

  • Moderate moisturizing. It has a moisturizing rating of 5.0 out of 10.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: The INKEY List Alpha Hydroxy Acid Serum has a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Propanediol (est. ≈6.0%), Glycerin (est. ≈3.0%) and Saccharum Officinarum (Sugarcane) Extract (est. ≈2.0%).Tip: Studies suggest that humectants alone do not moisturize the skin. We recommend applying a product with some occlusive ingredients after the use of this one.

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

Anti-wrinkle efficacy

According to CreamScan analysis, The INKEY List Alpha Hydroxy Acid Serum has a zero anti-wrinkle rating.

It contains Ascorbyl Glucoside, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Ascorbyl Glucoside provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not generate the anti-wrinkle rating.

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

Antioxidant benefits

We estimate that The INKEY List Alpha Hydroxy Acid Serum is rich (> 3%) in antioxidants, specifically Vaccinium Myrtillus Fruit Extract (est. ≈4.0%) and Saccharum Officinarum (Sugarcane) Extract (est. ≈2.0%).

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.

Ingredients explained

Water
Est. %80
Function
Origin
The 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.
Propanediol
Est. %6
Function
Origin
An 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.
Vaccinium Myrtillus Fruit Extract
Est. %4
Function
Origin
An extract derived from the berries of the bilberry plant, sometimes called European blueberry. It is rich in antioxidant anthocyanins and astringent tannins.
Glycerin
Est. %3
Function
Origin

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

Saccharum Officinarum (Sugarcane) Extract
Est. %2
Function
Origin
An antioxidant extract from sugarcane, the famous crop used to make sugar. It acts as a humectant and exfoliating agent – the little sugar crystals mechanically remove dead skin cells from the skin’s surface.
Ascorbyl Glucoside
Est. %1.5
Function
Origin
A 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. %1.3
Function
Origin
An ingredient that is able to bring the pH of a product up, thereby making it less harsh on the skin.
Sodium Hyaluronate
Est. %1
Function
Origin
A sodium salt of famous hyaluronic acid. A potent humectant that hydrates the skin, supports collagen function, and fills out small wrinkles. Sodium hyaluronate also offers soothing and antioxidant properties.
Citrus Aurantium Dulcis (Orange) Fruit Extract
Est. %0.3
Function
Origin
An extract from the fruit of the sweet orange. It contains fragrant sweet orange essential oil, high amounts of antioxidant flavonoids (mainly hesperidin), and carotenoids – which give it the orange color.
Citrus Limon (Lemon) Fruit Extract
Est. %0.3
Function
Origin
A fragrant extract from lemon peels that contains various antioxidant flavonoids, organic acids, and limonoids – which are currently under investigation as potential anti-wrinkle and anti-pigment compounds.
Xanthan Gum
Est. %0.3
Function
Origin
A 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.
Acer Saccharum (Sugar Maple) Extract
Est. %0.3
Function
Origin
An antioxidant extract from sugar maple bark and sap – the same sweet sap used to make maple syrup. It has a faint vanilla smell and is used in skincare for its exfoliating properties. This is because of the small sugar crystals present in the extract.
Sodium Benzoate
Est. %0.3
Function
Origin
A preservative that usually works in combination with other preservatives. It has to be at low pH (<5.5) to be effective.
Allantoin
Est. %0.3
Function
Origin
A fluffy, white powder that acts as a humectant due to its water-loving chemistry and as an exfoliant that helps to remove dead skin cells. It has also been shown to be very soothing to irritated and inflamed skin.
Sodium Levulinate
Est. %0.3
Function
Origin
A sodium salt of levulinic acid that is used as an antimicrobial and preservative agent, inhibiting the growth of harmful bacteria in a product.
Potassium Sorbate
Est. %0.3
Function
Origin
A preservative widely used in food and personal care products, available from natural sources or synthetically produced. Potassium sorbate works by inhibiting the growth of yeasts, molds, and some bacteria.
Sodium Anisate
Est. %0.3
Function
Origin
A natural preservative with a sweet scent.
Trisodium Ethylenediamine Disuccinate
Est. %0.3
Function
Origin
A chelating agent that disables harmful heavy metal ions present in skincare.
