Kate Somerville KX Concentrate Bio-Mimicking Peptides Serum

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: sh-oligopeptide-1, sh-oligopeptide-2, sh-polypeptide-1, sh-polypeptide-11, sh-polypeptide-9.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, sodium hyaluronate.

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: panthenol, sh-oligopeptide-1, sh-oligopeptide-2, sh-polypeptide-1, sh-polypeptide-11, sh-polypeptide-9

This product contains ingredients (glycine soja seed extract) that could help reduce hyperpigmentation (for example, post-acne marks or age spots) in theory, but there is not enough evidence that they actually work.
