Does REN Clean Skincare Brightening Dark Circle Eye Cream work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using REN Clean Skincare Brightening Dark Circle Eye Cream:

  • Significant moisturizing. It has a moisturizing rating of 6.1 out of 10.

Lightweight moisturizer perfect for oily to normal skin

According to CreamScan analysis, REN Clean Skincare Brightening Dark Circle Eye Cream is highly moisturizing, with a moisturizing rating of 6.1 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a very high humectancy of 8.7 out of 10, primarily due to the substantial concentration of Glycerin (est. ≈6.0%), and a moderate occlusivity of 3.5 out of 10, mainly due to the significant content of Caprylic/Capric Triglyceride (est. ≈4.0%).

This type of moisturizer is ideal for people with oily skin who want maximum hydration in a relatively lightweight, non-greasy formula. It combines a significant amount of humectants with a limited amount of occlusive ingredients to boost moisturizing efficacy without feeling too heavy.

This product may also be a good choice for people with normal skin who prefer fast-absorbing textures, 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, REN Clean Skincare Brightening Dark Circle Eye Cream has a zero anti-wrinkle rating.

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