Results you may expect from using Credentials Replenish System Eye Nourisher:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Credentials Replenish System Eye Nourisher:

  • Light moisturizing. It has a moisturizing rating of 3.6 out of 10.
  • Little anti-wrinkle effect: Credentials Replenish System Eye Nourisher has an anti-wrinkle rating of 0.1 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Lightly moisturizing: Credentials Replenish System Eye Nourisher has a moisturizing rating of 3.6 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a low occlusivity of 2.2 out of 10 and a moderate humectancy of 4.9 out of 10, primarily due to Glycerin (est. ≈1.3%), Glycyrrhiza Glabra (Licorice) Root Extract (est. ≈0.3%) and Saccharum Officinarum (Sugarcane) Extract (est. ≈0.3%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Credentials Replenish System Eye Nourisher has a minimal anti-wrinkle rating of 0.1 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈0.3%),
 or Vitamin C, a popular anti-wrinkle ingredient, yet with average efficacy confirmed by only one study.
 
Among others, Credentials Replenish System Eye Nourisher also contains some ingredients marketed as effective in reducing wrinkles, specifically Magnesium Ascorbyl Phosphate, Retinyl Palmitate, and Ubiquinone. 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 Credentials Replenish System Eye Nourisher is rich (> 3%) in antioxidants, specifically Magnesium Ascorbyl Phosphate (est. ≈0.3%), Glycyrrhiza Glabra (Licorice) Root Extract (est. ≈0.3%), Saccharum Officinarum (Sugarcane) Extract (est. ≈0.3%), and others.

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. %60
Function
Origin
The 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.
Cyclomethicone
Est. %9
Function
Origin
A blend of emollient silicones that leaves a smooth and non-greasy after-feel. Unlike other types of oils, it does not leave any residue on the skin, which is part of what makes it so popular.

Urea
Est. %0.3
Function
Origin
Urea can be found in urine, skin, and other tissues as a degradation product of proteins. In concentrations below 5%, urea is humectant moisturizing. At concentrations above 10% it is keratolytic, that helps to break away old, flaking, and cracked skin.
Ascorbic Acid
Est. %0.3
Function
Origin

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.

Est. %0.3
Function
Origin
Description is coming soon
Retinyl Palmitate
Est. %0.3
Function
Origin
An esterified form of retinol – it combines retinol and palmitic acid into one molecule. Retinyl palmitate is less irritating than retinol but also much less effective in its anti-aging and acne-reducing effects.
Tocopherol

Function
Origin
An elastic protein of animal origin that has been processed into smaller, water-soluble peptide fragments. It can be used to treat rough and chapped skin, as well as combat skin dryness.
Soluble Collagen
Est. %0.3
Function
Origin
A protein obtained from farm or marine animals. Collagen molecules are too big to penetrate the skin so when they are applied via a skincare product they sit on top of the skin and act as humectant moisturizers.
Butylene Glycol
Est. %0.3
Function
Origin
A 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.
Propylene Glycol
Est. %0.3
Function
Origin
A clear, thick, odorless liquid of synthetic origin. Its main function is to stabilize cosmetic products exposed to varying temperatures. It is also a moderately strong humectant with similar properties to glycerin.

Origin
A preservative that keeps a product unspoiled. There has been a lot of controversy surrounding parabens, although the concentrations found in cosmetic formulations are generally considered to be safe.
Phenoxyethanol
Est. %0.3
Function
Origin
The most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
Tetrasodium EDTA
Est. %0.3
Function
Origin
One of the most common synthetic chelators. It can reduce the 'hardness' of water and so is often used in rinse-off products.
