"The INKEY List CA - Peptide Moisturiser" is a well-rounded moisturizing product. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. The INKEY List CA - Peptide Moisturiser ticks this box. Betaine, glycerin and butylene glycol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Caprylic/capric triglyceride, c12-15 alkyl benzoate and cetearyl alcohol in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.
Ingredient callouts
This moistruizer also contains peptides (acetyl hexapeptide-37 0.05% - 0.30%). Peptides is a very big group of ingredients. They all consist of a different combination of amino-acids. Our skin produces peptides naturally. Some of them work as natural anti-biotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of peptides is, but it is very likely that peptides in skincare are helpful. They might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
Irritation risk

2% Royal Epigen P5 helps contribute to firm, even skin with a decreased appearance of fine lines and wrinkles 1% Hydrating Peptide Solution supports your skin’s natural moisture barrier for visibly radiant skin
This product contains acetyl hexapeptide-37, pentapeptide-48.
These ingredients might be able to help
reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough
evidence that it actually works.
A type of peptide, sold under the brand name Royal Epigen P5. It consists five different amino-acids: arginine, glutamic acid, leucine, serine and threonine. It helps attract water to the upper layer of the skin and might have anti-aging benefits. One of the manufacturers discloses that creation of this peptide was inspired by a protein found in royal jelly. There is no evidence that this is in any way relevant to this ingredient's benefit for human skin. There are no clinical trials available for this ingredient. There is also no lab tests methodology and results disclosed for it. It is not clear if this peptide has an actual anti-aging or would healing properties when applied topically to human skin. The ingredient manufacturer recommends to include it in formulations at 2-3%.
A great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”: these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
betaine, glycerin.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses
moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels
less tight and nicer to the touch. The following ingredients in this product do the job:
caprylic/capric triglyceride, c12-15 alkyl benzoate.
The following ingredients in this product are especially good for supporting the skin barrier and helping with
the hydration level: acetyl hexapeptide-37
Works for:
Moisturizing,
Anti-aging,
Anti-oxidation
