Peptides (acetyl hexapeptide-8 0.05% - 0.25% and acetyl octapeptide-3 0.10% - 0.40%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. They might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
Humectants (sodium hyaluronate 0.10% - 0.30%, glycerin 3.90% - 5.90%, acetyl hexapeptide-8 0.05% - 0.25%, acetyl octapeptide-3 0.10% - 0.40%, arginine 0.10% - 0.45% and betaine 1.30% - 2.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

This product contains acetyl hexapeptide-8, acetyl octapeptide-3, serine. 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.

acetyl hexapeptide-8 0.05% - 0.25%

Irritation risk:

Concentration: Effectiveness: MEDIUM

A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles

acetyl octapeptide-3 0.1% - 0.4%

A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles

serine 0.1% - 0.45%

Irritation risk:

Concentration: Effectiveness: MEDIUM

An amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles

Moisturizing

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: arginine, betaine.

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: arginine, chondrus crispus extract.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, acetyl octapeptide-3

sodium hyaluronate 0.1% - 0.3%

Irritation risk:

Concentration: Effectiveness: HIGH

One of the best moisturizing ingredients. Attracts water into the upper layer of the skin

acetyl octapeptide-3 0.1% - 0.4%

Irritation risk:

Concentration: Effectiveness: HIGH

A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles

arginine 0.1% - 0.45%

Irritation risk:

Concentration: Effectiveness: HIGH

An amino acid that is naturally present in skin and helps keep it hydrated. When used together with AHAs, it can reduce their irritating effect on the skin
