Review

Results you may expect from using Yves Saint Laurent Forever Youth Liberator Eye Zone Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Yves Saint Laurent Forever Youth Liberator Eye Zone Serum:

  • Moderate moisturizing. It has a moisturizing rating of 5.0 out of 10.

How moisturizing is it?

Quite moisturizing: Yves Saint Laurent Forever Youth Liberator Eye Zone Serum 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 Glycerin (est. ≈6.0%) and Butylene Glycol (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, Yves Saint Laurent Forever Youth Liberator Eye Zone Serum has a zero anti-wrinkle rating.

It contains Adenosine, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Adenosine 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.
