Ingredient callouts
Peptides (acetyl hexapeptide-8 1.40% - 2.10%). 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 (soluble collagen 0.55% - 1.25%, aspartic acid 0.85% - 1.25%, acetyl hexapeptide-8 1.40% - 2.10%, hydrolyzed hyaluronic acid 1.70% - 2.50% and glycerin 3.60% - 5.30%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
This product contains acetyl hexapeptide-8, aspartic acid.
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.
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called
"humectants":
aspartic acid, glycerin.
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. If the air is dry, humectants can speed up the moisture loss from the skin. This
is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for
ingredients like dimethicone, squalane, oils and butters).
The following ingredients in this product are especially good for supporting the skin barrier and helping with
the hydration level: acetyl hexapeptide-8
