Things to Be Aware Of: The INKEY List Hepta-Peptide Anti-Aging Serum

 
CreamScan identified a few things to consider before adding The INKEY List Hepta-Peptide Anti-Aging Serum to your skincare routine:
 

⚠️ As a Standalone Moisturizer, It Has Relatively Low Moisturizing Potential

If you use The INKEY List Hepta-Peptide Anti-Aging Serum for moisturizing purposes, please keep in mind that it provides relatively light moisturizing on its own, and, more importantly, it’s not optimal for any skin type.

On one hand, it has low occlusivity, which suits oily and combination skin. On the other hand, it has a low estimated concentration of humectants, which are essential for effective moisturizing of all skin types, including oily skin.

Therefore, if used as a standalone moisturizer, this product should be paired with a humectant-rich moisturizer for optimal skin hydration.

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.
Polysilicone-11
Est. %6
Function
Origin
Polysilicone-11A synthetic rubber-like substance of the silicone family that has no color or distinct scent. These are large molecules that cannot penetrate the skin but instead create a thin silky film on the skin's surface.
Hydrogenated Polydecene
Est. %4
Function
Origin
Hydrogenated PolydeceneA clear, colorless, highly viscous liquid that commonly serves as an emollient. This rich emollient is on the heavier side but provides a smooth sensorial profile upon application.
Hydrogenated Polyisobutene
Est. %3
Function
Origin
Hydrogenated PolyisobuteneA viscous liquid that makes a great oil base due to its smooth sensorial profile. It has emollient features, including good spreadability and little tack upon application. It also has the added benefit of being able to thicken products.
Polymethylsilsesquioxane
Est. %2
Function
Origin
PolymethylsilsesquioxaneA type of spherical powder that functions on a ball-bearing effect in which the tiny microspheres roll around on the skin and create lubricity. Polymethylsilsesquioxane offers extra slip to skincare products and makes the skin feel soft and smooth.
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.
Sodium Caproyl Prolinate
Est. %1
Function
Origin
Sodium Caproyl Prolinate
Laureth-12
Est. %1
Function
Origin
Laureth-12
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.

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.
Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer
Est. %0.3
Function
Origin
Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate CopolymerAn emulsion stabilizer and thickener that helps to create a pleasant, satiny, and light formula texture. It works by forming a gel-like network within water or oil, which both stabilizes other ingredients and produces a thickening effect.
Squalane
Est. %0.3
Function
Origin
SqualaneAn occlusive moisturizing and emollient compound that forms part of the skin’s sebum. The main source of squalane had always been shark liver. Now, however, it is manufactured synthetically or derived from plant oils, such as olive and peanut oil.
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.
Carnosine
Est. %0.3
Function
Origin
CarnosineA skin-identical dipeptide that acts as a powerful antioxidant. It protects our skin from harmful glycation and can enhance the activity of other active ingredients in the skincare product.
Sodium Hydroxide
Est. %0.3
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.

Glycerin
Est. %0.3
Function
Origin
Glycerin

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

Trisodium Ethylenediamine Disuccinate
Est. %0.3
Function
Origin
Trisodium Ethylenediamine DisuccinateA chelating agent that disables harmful heavy metal ions present in skincare.
Polysorbate 60
Est. %0.3
Function
Origin
Polysorbate 60An ester based on sorbitan. It is good for emulsifying water and oils together – specifically making oil-in-water emulsions. Polysorbate 60 is also said to give a product a notable fragrance.
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.
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.
Heptapeptide-7
Est. %0.3
Function
Origin
Heptapeptide-7
Lecithin
Est. %0.3
Function
Origin
LecithinA humectant, emollient, and emulsifier best suited for water-in-oil emulsions. Lecithin can come from sunflowers, soy, and eggs. The downside to lecithin is that it causes an extra burden on the formula’s preservative because it is nutritious.
Potassium Sorbate
Est. %0.3
Function
Origin
Potassium SorbateA 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.
Propanediol
Est. %0.3
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.
Sodium Benzoate
Est. %0.3
Function
Origin
Sodium BenzoateA preservative that usually works in combination with other preservatives. It has to be at low pH (<5.5) to be effective.
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.
Sorbitan Isostearate
Est. %0.3
Function
Origin
Sorbitan IsostearateA mild yet powerful emulsifier primarily utilized to produce water-in-oil emulsions. It helps to create a particularly rich and substantial emulsion.
