Review

Results you may expect from using La Prairie Skin Caviar Harmony LExtrait Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using La Prairie Skin Caviar Harmony LExtrait Serum:

  • Significant moisturizing. It has a moisturizing rating of 6.0 out of 10.
  • Antioxidant protection.

How moisturizing is it?

Highly moisturizing: La Prairie Skin Caviar Harmony LExtrait Serum has a moisturizing rating of 6.0 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 2.0 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%) and Isopentyldiol (est. ≈3.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, La Prairie Skin Caviar Harmony LExtrait Serum has a zero anti-wrinkle rating.

It contains Lactobacillus Ferment, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Lactobacillus Ferment provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does 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.

Antioxidant benefits

We estimate that La Prairie Skin Caviar Harmony LExtrait Serum is rich (> 3%) in antioxidants, specifically Glycoproteins (est. ≈1.3%), Panax Ginseng Root Extract (est. ≈1.0%), Equisetum Arvense Extract (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.
