Review

Does Bonajour Extreme Spot Serum work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Bonajour Extreme Spot Serum:

  • Moderate moisturizing. It has a moisturizing rating of 5.0 out of 10.
  • Considerable anti-wrinkle efficacy: Bonajour Extreme Spot Serum has an anti-wrinkle rating of 4.5 out of 10, indicating a moderate ability to reduce wrinkles.
  • Soothing: Bonajour Extreme Spot 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: Bonajour Extreme Spot 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 Glycerin (est. ≈6.0%) and Niacinamide (est. ≈3.0%).

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, Bonajour Extreme Spot 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.
 
Among others, Bonajour Extreme Spot Serum also contains Centella Asiatica Extract, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Centella Asiatica Extract 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, could deliver additional anti-wrinkle efficacy through its moisturizing action.
 

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

Antioxidant benefits

We estimate that Bonajour Extreme Spot Serum is rich (> 3%) in antioxidants, specifically Centella Asiatica Extract (est. ≈80.0%) and 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.

Skin soothing

Based on the ingredient list analysis, Bonajour Extreme Spot Serum is rich (> 5%) in soothing ingredients, particularly Centella Asiatica Extract (est. ≈80.0%) and Niacinamide (est. ≈3.0%).

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.
