Key Benefits of Credentials Replenish System Eye Nourisher

 
These are the key benefits you can expect from using Credentials Replenish System Eye Nourisher:
 

Lightweight Moisturizer Suitable for Combination and Oily Skin

According to CreamScan analysis, Credentials Replenish System Eye Nourisher is lightly moisturizing, with 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%).

This type of moisturizer is suitable for people with oily and combination skin who want essential hydration in a relatively lightweight, non-greasy formula. It combines a substantial amount of humectants with a limited amount of occlusive ingredients to enhance moisturizing efficacy without feeling too heavy.

A Humectant Add-on for Any Skincare Routine

But it’s not limited to combination and oily skin - since it contains a moderate amount of humectants, such a humectant add-on will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer.

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

Slight Anti-Wrinkle Efficacy

According to CreamScan analysis, Credentials Replenish System Eye Nourisher has a slight 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 ingredient, yet with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 20 participants (Humbert et al.). This study showed that a cream with a relatively high concentration of 5% ascorbic acid reduced the average wrinkle depth by 7% after 6 months of use, compared to a vehicle (the same formulation without ascorbic acid).
 
Among others, Credentials Replenish System Eye Nourisher also contains some ingredients marketed often 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, can deliver some anti-wrinkle effects through its moisturizing action.
 

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

Rich in Skin-Protecting Antioxidants

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.

Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Butylene Glycol
Est. %0.3
Function
Origin
Butylene Glycol

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.

Phenoxyethanol
Est. %0.3
Function
Origin

Tetrasodium EDTA
Est. %0.3
Function
Origin
Tetrasodium EDTAOne of the most common synthetic chelators. It can reduce the 'hardness' of water and so is often used in rinse-off products.
