Review

Results you may expect from using Avon Isa Knox Anew LX Ultimate Rejuvenating Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Avon Isa Knox Anew LX Ultimate Rejuvenating Serum:

  • Moderate moisturizing. It has a moisturizing rating of 5.8 out of 10.
  • Some anti-wrinkle efficacy: Avon Isa Knox Anew LX Ultimate Rejuvenating Serum has an anti-wrinkle rating of 2.0 out of 10 so you may expect some, although limited, effect on wrinkles.

How moisturizing is it?

Quite moisturizing: Avon Isa Knox Anew LX Ultimate Rejuvenating Serum has a moisturizing rating of 5.8 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 1.6 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%) and PEG/PPG/Polybutylene Glycol-8/5/3 Glycerin (est. ≈3.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Avon Isa Knox Anew LX Ultimate Rejuvenating Serum has a slight anti-wrinkle rating of 2.0 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈1.3%), 
 one of the most effective and well-researched anti-wrinkle ingredients.
 
Among others, Avon Isa Knox Anew LX Ultimate Rejuvenating Serum also contains contains Adenosine and Beta-Glucan, two ingredients marketed as effective in reducing wrinkles. 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 contribute to 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 additional anti-wrinkle efficacy through its moisturizing action.
 

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