Review

Results you may expect from using Herbitage C-Signature 27.5 Brightening Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Herbitage C-Signature 27.5 Brightening Serum:

  • A bit of moisturizing. It has a moisturizing rating of 1.8 out of 10.
  • Considerable anti-wrinkle efficacy: Herbitage C-Signature 27.5 Brightening Serum has an anti-wrinkle rating of 5.5 out of 10, indicating a moderate ability to reduce wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Slightly moisturizing: Herbitage C-Signature 27.5 Brightening Serum has a moisturizing rating of 1.8 out of 10.

Is it more humectant or occlusive? Purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a moderate humectancy of 3.6 out of 10, primarily due to the high content of Ethoxydiglycol (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, Herbitage C-Signature 27.5 Brightening Serum has a moderate anti-wrinkle rating of 5.5 out of 10.

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

  • Asiaticoside (est. ≈0.3%),
     derived from the plant Centella asiatica, an ingredient with moderate anti-wrinkle efficacy confirmed by one study.
  • Ascorbic Acid (est. ≈6.0%),
     or Vitamin C, a popular anti-wrinkle ingredient, yet with average efficacy confirmed by only one study.
Among others, Herbitage C-Signature 27.5 Brightening Serum also contains contains Madecassic Acid and Asiatic Acid, two ingredients marketed as effective in reducing wrinkles. 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.
 
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 Herbitage C-Signature 27.5 Brightening Serum is rich (> 3%) in antioxidants, specifically Ascorbic Acid (est. ≈6.0%).

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.

Ingredients explained

Water
Est. %75
Function
Origin
WaterThe most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Ascorbic Acid
Est. %6
Function
Origin
Ascorbic Acid

Also known as vitamin C, this multi-benefit ingredient has proven anti-wrinkle, antioxidant, and anti-pigmentation efficacy. It degrades easily when exposed to air and light, so it requires proper packaging to maintain its stability.
