Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 2.3 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈9.0%) and Butylene Glycol (est. ≈4.0%).

Anti-wrinkle efficacy

According to CreamScan analysis, Yves Saint Laurent Forever Youth Liberator Eye Cream 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.
