Key Benefits of REN Clean Skincare Bio Retinoid Youth Serum

 
These are the key benefits you can expect from using REN Clean Skincare Bio Retinoid Youth Serum:
 

Perfect Moisturizer for Normal to Dry Skin with a Balanced Texture, Neither Too Light nor Too Heavy

According to CreamScan analysis, REN Clean Skincare Bio Retinoid Youth Serum is highly moisturizing, with a moisturizing rating of 6.6 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a very high humectancy of 8.2 out of 10, primarily due to the substantial concentration of Glycerin (est. ≈4.0%) and Niacinamide (est. ≈3.0%), and a moderate occlusivity of 5.0 out of 10, mainly due to the significant content of Caprylic/Capric Triglyceride (est. ≈6.0%).

This type of moisturizer is ideal for people with normal skin who want maximum hydration in a formula with a balanced texture - neither too light nor too heavy. 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 balanced texture, neither too light nor too heavy.

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

Considerable Anti-Wrinkle Efficacy

According to CreamScan analysis, REN Clean Skincare Bio Retinoid Youth Serum has a moderate anti-wrinkle rating of 4.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈3.0%), 
 one of the most effective and well-researched anti-wrinkle ingredients. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
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 Bio Retinoid Youth Serum is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈3.0%).

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.

Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: REN Clean Skincare Bio Retinoid Youth Serum

 
CreamScan AI identified a few things to consider before adding REN Clean Skincare Bio Retinoid Youth Serum to your skincare routine:
 

If It’s an Exfoliator, It May Increase Skin Photosensitivity Due to Lactic Acid

This product contains lactic acid, a popular AHA known for its ability to gently exfoliate and brighten the skin. It works by removing dead skin cells, revealing new, more delicate skin that is more vulnerable to sun damage.

In smaller quantities, lactic acid is often used as a pH adjuster and may not significantly contribute to exfoliation. However, at higher concentrations, it functions as an effective exfoliant with benefits and risks similar to other AHAs. Products with AHAs, including lactic acid, may increase skin sensitivity, making it more prone to sunburn or irritation when exposed to UV rays.

If this product is designed for exfoliation, applying a broad-spectrum sunscreen with at least SPF 30 daily is essential to protect your skin. Always check the label or the manufacturer’s website for specific usage instructions.
