Review

Results you may expect from using Kate Somerville KateCeuticals Firming Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Kate Somerville KateCeuticals Firming Serum:

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

How moisturizing is it?

Quite moisturizing: Kate Somerville KateCeuticals Firming Serum has a moisturizing rating of 4.6 out of 10.

Is it more humectant or occlusive? This product has relatively comparable levels of humectancy and occlusivity: a moderate humectancy of 5.9 out of 10, primarily due to the substantial concentration of Glycerin (est. ≈3.0%) and Propanediol (est. ≈2.0%), and a moderate occlusivity of 3.3 out of 10, mainly due to the high content of Dimethicone (est. ≈6.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Kate Somerville KateCeuticals Firming Serum has a zero anti-wrinkle rating.

It contains some ingredients marketed as effective in reducing wrinkles, specifically Dipalmitoyl Hydroxyproline, Adenosine, and Palmitoyl Tripeptide-5. 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.

Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, could deliver some anti-wrinkle effects through its moisturizing action.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.
