Review

Results you may expect from using Klued 0.5% Retinol Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Klued 0.5% Retinol Serum:

  • Intense moisturizing. It has a moisturizing rating of 9.7 out of 10.
  • Potent anti-wrinkle effect. With an anti-wrinkle rating of 10.0 out of 10, Klued 0.5% Retinol Serum is highly potent in reducing wrinkles.

How moisturizing is it?

Intensely moisturizing: Klued 0.5% Retinol Serum has a moisturizing rating of 9.7 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Butylene Glycol (est. ≈22.0%) and Glycerin (est. ≈6.0%), and a very high occlusivity of 9.4 out of 10, mainly due to the significant content of Stearic Acid (est. ≈11.0%) and Vitis Vinifera (Grape) Seed Oil (est. ≈4.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Klued 0.5% Retinol Serum has a maximum anti-wrinkle rating of 10.0 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Retinol (est. ≈0.5%),
 the most effective non-prescription ingredient with well-proven efficacy to reduce wrinkles.
 
Among others, Klued 0.5% Retinol Serum also contains Camellia Sinensis Leaf Extract, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Camellia Sinensis Leaf Extract provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not contribute to the anti-wrinkle rating.
 

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

Antioxidant benefits

We estimate that Klued 0.5% Retinol Serum is rich (> 3%) in antioxidants, specifically Vitis Vinifera (Grape) Seed Oil (est. ≈4.0%) and Camellia Sinensis Leaf Extract (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.

Butylene Glycol
Est. %22
Function
Origin
Butylene GlycolA clear, colorless liquid humectant that draws moisture to the skin. The humectancy of butylene glycol, owed to its two hydroxyl groups, is quite considerable, although not as powerful as glycerin, which contains three hydroxyl groups.
Stearic Acid

Triethanolamine
Est. %0.3
Function
Origin
TriethanolamineA clear, colorless, and highly viscous liquid, this ingredient is an excellent pH adjuster. When it is necessary to neutralize an acidic solution or to generally increase the pH of a product, triethanolamine is a common choice.
