Review

Results you may expect from using Kerstin Florian Clarifying Probiotic Mineral Tonic:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Kerstin Florian Clarifying Probiotic Mineral Tonic:

  • Moderate moisturizing. It has a moisturizing rating of 5.0 out of 10.
  • Little anti-wrinkle effect: Kerstin Florian Clarifying Probiotic Mineral Tonic has an anti-wrinkle rating of 0.1 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.
  • Soothing: Kerstin Florian Clarifying Probiotic Mineral Tonic contains a high concentration of soothing ingredients, which may help to reduce irritation and calm the skin.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: Kerstin Florian Clarifying Probiotic Mineral Tonic has a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Pentylene Glycol (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, Kerstin Florian Clarifying Probiotic Mineral Tonic has a minimal anti-wrinkle rating of 0.1 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Glycolic Acid (est. ≈0.3%),
 highly effective in peelings, yet with below-average anti-wrinkle efficacy when used in leave-on skincare products.
 
Among others, Kerstin Florian Clarifying Probiotic Mineral Tonic also contains contains Lactobacillus Ferment and Copper Gluconate, 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.

Antioxidant benefits

We estimate that Kerstin Florian Clarifying Probiotic Mineral Tonic is rich (> 3%) in antioxidants, specifically Vaccinium Myrtillus Fruit Extract (est. ≈2.0%).

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.

Skin soothing

Based on the ingredient list analysis, Kerstin Florian Clarifying Probiotic Mineral Tonic is rich (> 5%) in soothing ingredients, particularly Lactobacillus Ferment (est. ≈6.0%).

When applied to the skin, compounds of soothing ingredients, such as triglycerides, phospholipids, fatty acids, phenolic compounds, and antioxidants, work together to soothe the skin through various mechanisms: reducing inflammation, promoting wound healing, repairing the skin barrier, and providing antimicrobial and antioxidant activities.
