Review

Results you may expect from using Biopelle KNR Brightening Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Biopelle KNR Brightening Serum:

  • Moderate moisturizing. It has a moisturizing rating of 5.0 out of 10.
  • Potent anti-wrinkle effect. With an anti-wrinkle rating of 9.7 out of 10, Biopelle KNR Brightening Serum is highly potent in reducing wrinkles.
  • Soothing: Biopelle KNR Brightening Serum contains a high concentration of soothing ingredients, which may help to reduce irritation and calm the skin.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: Biopelle KNR Brightening Serum has a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Butylene Glycol (est. ≈6.0%), Glycerin (est. ≈4.1%) and Niacinamide (est. ≈4.0%).

Tip: Studies suggest that humectants alone do not moisturize the skin. We recommend applying a product with some occlusive ingredients after the use of this one.

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

Anti-wrinkle efficacy

According to CreamScan analysis, Biopelle KNR Brightening Serum has a very high anti-wrinkle rating of 9.7 out of 10.

It contains 2 active ingredients with proven anti-wrinkle efficacy:

  • Niacinamide (est. ≈4.0%),
     one of the most effective and well-researched anti-wrinkle ingredients.
  • Retinol (est. ≈0.15%),
     the most effective non-prescription ingredient with well-proven efficacy to reduce wrinkles.
Among others, Biopelle KNR Brightening Serum also contains some ingredients marketed as effective in reducing wrinkles, specifically Acetyl Glucosamine, Hydroxypinacolone Retinoate, and Tetrahexyldecyl Ascorbate. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. Therefore, these ingredients do 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 Biopelle KNR Brightening Serum is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈4.0%), Portulaca Oleracea Extract (est. ≈2.2%) and Kojic Acid (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.

Skin soothing

Based on the ingredient list analysis, Biopelle KNR Brightening Serum is rich (> 5%) in soothing ingredients, particularly Niacinamide (est. ≈4.0%) and Portulaca Oleracea Extract (est. ≈2.2%).

When applied to the skin, compounds of soothing ingredients, such as triglycerides, phospholipids, fatty acids, phenolic compounds, and antioxidants, work together to soothe the skin through various mechanisms: reducing inflammation, promoting wound healing, repairing the skin barrier, and providing antimicrobial and antioxidant activities.
