Does REN Clean Skincare Radiance Perfection Serum work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using REN Clean Skincare Radiance Perfection Serum:

  • Moderate moisturizing. It has a moisturizing rating of 4.8 out of 10.
  • Some anti-wrinkle efficacy: REN Clean Skincare Radiance Perfection Serum has an anti-wrinkle rating of 2.0 out of 10 so you may expect some, although limited, effect on wrinkles.
  • Antioxidant protection.

Lightweight moisturizer well-suited for oily skin and a humectant enhancement for any skincare routine

According to CreamScan analysis, REN Clean Skincare Radiance Perfection Serum is quite moisturizing, with a moisturizing rating of 4.8 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 1.8 out of 10 and a high humectancy of 7.8 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%).

This humectant-rich product, when used alone as a moisturizer, is well-suited for oily skin, providing moderate hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients. It can also be a good option for people with normal skin who prefer lightweight moisturizers.

Such a humectant engancement will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

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

Some anti-wrinkle efficacy

According to CreamScan analysis, REN Clean Skincare Radiance Perfection Serum has a slight anti-wrinkle rating of 2.0 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ascorbyl Tetraisopalmitate (est. ≈2.0%), 
 the only derivative of ascorbic acid with solid evidence of anti-wrinkle efficacy. A single clinical study involving 23 participants (Mariko et al.) demonstrated that a cream with 1% ATIP reduced the average depth of periorbital wrinkles by 6% after 8 weeks of use, compared to a vehicle (the same formulation without ATIP).
 
Among others, REN Clean Skincare Radiance Perfection Serum also contains Magnesium Ascorbyl Phosphate, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Magnesium Ascorbyl Phosphate provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not contribute to 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.

Rich in skin-protecting antioxidants

We estimate that REN Clean Skincare Radiance Perfection Serum is rich (> 3%) in antioxidants, specifically Ascorbyl Tetraisopalmitate (est. ≈2.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.
