Review

Results you may expect from using The INKEY List Collagen Booster Firming Peptide Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using The INKEY List Collagen Booster Firming Peptide Serum:

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

How moisturizing is it?

Quite moisturizing: The INKEY List Collagen Booster Firming Peptide 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 Glycerin (est. ≈6.0%), Butylene Glycol (est. ≈4.0%) and Propanediol (est. ≈3.0%).

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 Collagen Booster Firming Peptide Serum has a zero anti-wrinkle rating.

It contains some ingredients marketed as effective in reducing wrinkles, specifically Palmitoyl Dipeptide-5 Diaminobutyroyl Hydroxythreonine, Palmitoyl Tetrapeptide-7, and Palmitoyl Tripeptide-1. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. 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, could 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. %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.
Glycerin
Est. %6
Function
Origin

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

Butylene Glycol
Est. %4
Function
Origin
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.
Propanediol
Est. %3
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.
Phenoxyethanol
Est. %1
Function
Origin
The 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.
Hydroxyethylcellulose
Est. %1
Function
Origin
A naturally-derived thickener that can form clear gel textures without the slimy feeling, unlike some other natural gel-formers.
Disodium EDTA
Est. %0.3
Function
Origin
A synthetic chelator that helps to maintain the look and smell of a product by 'locking up' troublesome metal ions.
Leuconostoc/Radish Root Ferment Filtrate
Est. %0.3
Function
Origin
A biotechnological fermentation ingredient that is created by feeding radish root to Leuconostoc kimchii. It allegedly contains organic acids and a mixture of peptides known as bacteriocins – which have antimicrobial activity.
Carbomer
Est. %0.3
Function
Origin
A 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.
Hyaluronic Acid
Est. %0.3
Function
Origin
A potent, skin-identical humectant moisturizing ingredient that is able to bind water 1000 times its own weight. The anti-aging benefits of hyaluronic acid are due to its ability to stimulate the synthesis of collagen in the skin.
Palmitoyl Dipeptide-5 Diaminobutyroyl Hydroxythreonine
Est. %0.3
Function
Origin
A synthetically made peptide that was designed to target the dermo-epidermal junction, where it should stimulate the production of structural proteins. It has not been clinically tested yet.
Palmitoyl Dipeptide-5 Diaminohydroxybutyrate
Est. %0.3
Function
Origin
Description is coming soon
Polysorbate 20
Est. %0.3
Function
Origin
A viscous, amber-colored liquid that functions as a solubilizer to disperse small amounts of oil into a large water phase. Polysorbate 20 is frequently used to solubilize fragrance oils into water-based emulsions.
Palmitoyl Tetrapeptide-7
Est. %0.3
Function
Origin

A synthetic peptide that mimics the activity of immunoglobulin G and signals to the skin to stop the inflammation. It has been shown in studies to reduce wrinkles and enhance collagen content.

Palmitoyl Tripeptide-1
Est. %0.3
Function
Origin

A small peptide consisting of three amino acids with anti-wrinkle effects. Together with Palmitoyl Tetrapeptide-7, it is a part of the popular anti-wrinkle complex called Matrixyl™ 3000.
