Kate Somerville KX Concentrate Bio-Mimicking Peptides Serum
Works for
Anti-agingSh-oligopeptide-2, Sh-oligopeptide-1 + 5 moreWorks well
“This all-new Kx Active Concentrates Bio-Mimicking Peptides Serum was specially formulated to transform dull, sagging skin into visibly firmer, smoother, refreshed-looking skin.”
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-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.
MoisturizingSh-oligopeptide-2, Sh-oligopeptide-1 + 12 moreWorks well
“Safe for sensitive skin, this unites a complex of five peptides that are bio-identical, synthetic growth factors and visibly improve skin elasticity, rejuvenation and moisturisation while reducing wrinkles and fine lines.”
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

“Works to improve tone and texture while smoothing the look of fine lines and wrinkles”
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.

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.
