Does Kiehl's Ultra Facial Overnight Hydrating Mask work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Kiehl's Ultra Facial Overnight Hydrating Mask:

  • Significant moisturizing. It has a moisturizing rating of 7.1 out of 10.

Perfect moisturizer for normal to dry skin with a relatively lightweight texture

According to CreamScan analysis, Kiehl's Ultra Facial Overnight Hydrating Mask is highly moisturizing, with a moisturizing rating of 7.1 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Glycerin (est. ≈9.0%) and Propylene Glycol (est. ≈6.0%), and a moderate occlusivity of 4.2 out of 10, mainly due to the high content of Squalane (est. ≈4.0%) and Butyrospermum Parkii (Shea) Butter (est. ≈3.0%).

This type of moisturizer is ideal for people with normal skin. It combines a high concentration of humectants with a significant amount of occlusive ingredients to deliver effective dual-action moisturizing for normal skin.

This product may also be a good choice for people with normal to dry skin for daily hydration, as it balances significant moisturizing potential with a relatively lightweight texture.

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

Questionable anti-wrinkle efficacy

According to CreamScan analysis, Kiehl's Ultra Facial Overnight Hydrating Mask has a zero anti-wrinkle rating.

It contains Imperata Cylindrica Root Extract and Pseudoalteromonas Ferment Extract, two ingredients often 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 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, can deliver some anti-wrinkle effects through its moisturizing action.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.
