Review

Results you may expect from using Kerstin Florian Rejuvenating 24-Hour Moisture Creme:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Kerstin Florian Rejuvenating 24-Hour Moisture Creme:

  • Moderate moisturizing. It has a moisturizing rating of 5.5 out of 10.
  • Little anti-wrinkle effect: Kerstin Florian Rejuvenating 24-Hour Moisture Creme has an anti-wrinkle rating of 0.1 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: Kerstin Florian Rejuvenating 24-Hour Moisture Creme has a moisturizing rating of 5.5 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a high humectancy of 6.3 out of 10, primarily due to the substantial concentration of Pentylene Glycol (est. ≈6.0%), and a moderate occlusivity of 4.7 out of 10, mainly due to the significant content of Caprylic/Capric Triglyceride (est. ≈3.0%) and Dimethicone (est. ≈2.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Kerstin Florian Rejuvenating 24-Hour Moisture Creme has a minimal anti-wrinkle rating of 0.1 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈0.3%),
 or Vitamin C, a popular anti-wrinkle ingredient, yet with average efficacy confirmed by only one study.
 
Among others, Kerstin Florian Rejuvenating 24-Hour Moisture Creme also contains Ascorbyl Palmitate, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Ascorbyl Palmitate provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does 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.

Antioxidant benefits

We estimate that Kerstin Florian Rejuvenating 24-Hour Moisture Creme is rich (> 3%) in antioxidants, specifically Tocopherol (est. ≈1.5%), Borago Officinalis Seed Oil (est. ≈1.0%), Ascorbyl Palmitate (est. ≈0.3%), and others.

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.
