Results you may expect from using Haruharu Wonder Centella 4% TXA Dark Spot Go Away Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Haruharu Wonder Centella 4% TXA Dark Spot Go Away Serum:

  • Moderate moisturizing. It has a moisturizing rating of 5.0 out of 10.
  • Potent anti-wrinkle effect. With an anti-wrinkle rating of 9.1 out of 10, Haruharu Wonder Centella 4% TXA Dark Spot Go Away Serum is highly potent in reducing wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: Haruharu Wonder Centella 4% TXA Dark Spot Go Away 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 Propanediol (est. ≈6.0%), Niacinamide (est. ≈4.0%) and Butylene Glycol (est. ≈2.0%).

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, Haruharu Wonder Centella 4% TXA Dark Spot Go Away Serum has a very high anti-wrinkle rating of 9.1 out of 10.

It contains 3 active ingredients with proven anti-wrinkle efficacy:

  • Niacinamide (est. ≈4.0%),
     one of the most effective and well-researched anti-wrinkle ingredients.
  • Asiaticoside (est. ≈0.3%),
     derived from the plant Centella asiatica, an ingredient with moderate anti-wrinkle efficacy confirmed by one study.
  • Ascorbic Acid (est. ≈0.3%),
     or Vitamin C, a popular anti-wrinkle ingredient, yet with average efficacy confirmed by only one study.
Among others, Haruharu Wonder Centella 4% TXA Dark Spot Go Away Serum also contains some ingredients marketed as effective in reducing wrinkles, specifically Centella Asiatica Extract, Asiatic Acid, Madecassic Acid, and Sodium Ascorbyl Phosphate. 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 Haruharu Wonder Centella 4% TXA Dark Spot Go Away Serum is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈4.0%).

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.

Propanediol
Est. %6
Function
Origin
PropanediolAn excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.
