Review

Results you may expect from using Kate Somerville Kx Active Concentrates Bio-Mimicking Peptides Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Kate Somerville Kx Active Concentrates Bio-Mimicking Peptides Serum:

  • Moderate moisturizing. It has a moisturizing rating of 4.6 out of 10.

How moisturizing is it?

Quite moisturizing: Kate Somerville Kx Active Concentrates Bio-Mimicking Peptides Serum has a moisturizing rating of 4.6 out of 10.

Is it more humectant or occlusive? Purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a very high humectancy of 9.1 out of 10, primarily due to the high content of Glycerin (est. ≈4.0%) and Propanediol (est. ≈3.0%).

Tip: Studies suggest that humectants alone do not moisturize the skin. We recommend applying a product with some occlusive ingredients after the use of this one.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Anti-wrinkle efficacy

According to CreamScan analysis, Kate Somerville Kx Active Concentrates Bio-Mimicking Peptides Serum has a zero anti-wrinkle rating.

It contains some ingredients marketed as effective in reducing wrinkles, specifically sh-Polypeptide-1, sh-Oligopeptide-1, sh-Polypeptide-9, and Adenosine. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. Therefore, these ingredients do not generate the anti-wrinkle rating.

Zinc PCA
Est. %0.3
Function
Origin
A two-part ingredient: Zinc helps to control sebum and bacteria in acne-prone skin, while skin-identical PCA is a moisturizing humectant. Zinc PCA may even boost collagen production and so is researched as a potential anti-wrinkle ingredient.
Caprylyl Glycol
Est. %0.3
Function
Origin
An emollient that improves product spreadability and offers a silky feel on the skin. It also acts as a preservative booster that improves the efficacy of other preservatives. According to the manufacturer, it is also a humectant moisturizer.
Glycine Soja (Soybean) Seed Extract
Est. %0.3
Function
Origin
An antioxidant, soothing, and wound healing extract derived from soybeans. Soybeans are a famous source of phytoestrogens - plant compounds that have a similar effect to steroid hormones.
Lecithin
Est. %0.3
Function
Origin
A humectant, emollient, and emulsifier best suited for water-in-oil emulsions. Lecithin can come from sunflowers, soy, and eggs. The downside to lecithin is that it causes an extra burden on the formula’s preservative because it is nutritious.

Bacillus/Folic Acid Ferment Filtrate Extract
Est. %0.3
Function
Origin

Combined with folic acid and derived from Bacillus fermentation, this extract acts as a humectant, retaining moisture to keep skin hydrated, and as an antioxidant, shielding skin from free-radical damage.

Caprylhydroxamic Acid
Est. %0.3
Function
Origin
A chelating agent used alongside preservatives in order to boost their antimicrobial activity.
Silica
Est. %0.3
Function
Origin
A widely used cosmetic ingredient with the same chemical composition as the sand found on beaches. A common function of silica is its ability to control viscosity. In certain chemical forms, it can effectively thicken cream-style products.
Adenosine
Est. %0.3
Function
Origin

A key molecule responsible for energy transportation, signaling, and enzyme activity. Adenosine is a popular anti-wrinkle ingredient, however, the key study about its anti-wrinkle efficacy (1) does not meet CreamScan Research Evaluation Standards as it is not double-blind.

Benzyl Alcohol
Est. %0.3
Function
Origin
A multifunctional ingredient that is supplied as a clear, colorless liquid. Its main function is as a flavoring agent and fragrance. It also acts as a broad-spectrum preservative, solvent, and viscosity-controlling agent that thins the product.
Potassium Sorbate
Est. %0.3
Function
Origin
A preservative widely used in food and personal care products, available from natural sources or synthetically produced. Potassium sorbate works by inhibiting the growth of yeasts, molds, and some bacteria.
Butylene Glycol
Est. %0.3
Function
Origin
A clear, colorless liquid humectant that draws moisture to the skin. The humectancy of butylene glycol, owed to its two hydroxyl groups, is quite considerable, although not as powerful as glycerin, which contains three hydroxyl groups.
Hexylene Glycol
Est. %0.3
Function
Origin
A multifunctional ingredient that is best known for its use as a solvent. It can dissolve both water-based ingredients and oils. For this reason, it can also function as an emulsifier, allowing oil and water ingredients to mix and remain stable.
Disodium EDTA
Est. %0.3
Function
Origin
A synthetic chelator that helps to maintain the look and smell of a product by 'locking up' troublesome metal ions.
Citric Acid
Est. %0.3
Function
Origin
A gently exfoliating AHA that helps to remove the top layer of dead skin cells. In comparison to other AHAs, citric acid has been shown to be one of the least effective. It is also very commonly used as a stabilizing and pH-controlling agent.
Sodium Benzoate
Est. %0.3
Function
Origin
A preservative that usually works in combination with other preservatives. It has to be at low pH (<5.5) to be effective.
Xanthan Gum
Est. %0.3
Function
Origin
A natural multi-functional ingredient that originates from fermented sugars. Xanthan gum acts as a viscosity-building agent to thicken skincare products. It is also an excellent stabilizer and works well to hold other ingredients together.
