How moisturizing is it?

Intensely moisturizing: Kiehl's Age Defender Eye Repair has a moisturizing rating of 8.4 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Glycerin (est. ≈9.0%), and a high occlusivity of 6.7 out of 10, mainly due to the significant content of Dimethicone (est. ≈6.0%) and Theobroma Cacao (Cocoa) Seed Butter (est. ≈3.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Kiehl's Age Defender Eye Repair has a zero anti-wrinkle rating.

It contains some ingredients marketed as effective in reducing wrinkles, specifically Caffeine, Ascorbyl Glucoside, and Adenosine. 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 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.
