Product Summary
"Kate Somerville - KX Concentrate Bio-Mimicking Peptides Serum" is effective for: Anti-inflammatory, Moisturizing and Anti-aging
Ingredient callouts
- Peptides (sh-polypeptide-9 0.50% - 0.75%, sh-polypeptide-11 0.50% - 0.70%, sh-polypeptide-1 0.70% - 1.00%, sh-oligopeptide-2 0.60% - 0.85% and sh-oligopeptide-1 0.55% - 0.80%). 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.
- Adenosine 0.25% - 0.45%. It is a chemical present inside our skin cells. A clinical trial confirmed that topical application of Adenosine in a low concentration can reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where our mimic is the most active, for example, in the corners of the eyes or on the forehead).
- Humectants (zinc pca 0.45% - 0.70%, sodium hyaluronate 1.10% - 1.40%, panthenol 0.45% - 0.70% and glycerin 3.90% - 4.70%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
What does the product description say?
What Else You Need to Know This signature serum visibly treats and transforms dull, sagging skin while powerfully improving elasticity and firmness and revitalizing moisture for a fresher, younger-looking complexion.
Source: Sephora CA
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.
Might help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)

Moisturizing

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
