Does Sobel Skin Rx 4.5% Retinol Night Treatment work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Sobel Skin Rx 4.5% Retinol Night Treatment:

  • A bit of moisturizing. It has a moisturizing rating of 0.9 out of 10.

Slight Moisturizing When Used Alone

According to CreamScan analysis, Sobel Skin Rx 4.5% Retinol Night Treatment is slightly moisturizing, with a moisturizing rating of 0.9 out of 10.

Is it more humectant or occlusive? This product has relatively comparable levels of Humectancy and Occlusivity: a low Humectancy of 0.9 out of 10 and a low Occlusivity of 0.9 out of 10.

This type of product provides relatively light moisturizing on its own but can contribute to overall moisturizing efficacy when used as part of a skincare routine, alongside another moisturizer.

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

Some anti-wrinkle efficacy

According to CreamScan analysis, Sobel Skin Rx 4.5% Retinol Night Treatment has a slight anti-wrinkle rating of 2.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Retinol (est. ≈0.1%), 
 the most effective non-prescription anti-wrinkle ingredient. Numerous clinical studies have shown its positive effects at concentrations as low as 0.1%. A study with 36 participants (Kafi et al.) confirmed that a lotion containing 0.4% retinol reduced wrinkle severity by 21% after 24 weeks of use, compared to the same formulation without retinol (vehicle).
 
Among others, Sobel Skin Rx 4.5% Retinol Night Treatment also contains Hydroxypinacolone Retinoate, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Hydroxypinacolone Retinoate 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.
