Review

Results you may expect from using Credentials Overnight Oxy-Complex:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Credentials Overnight Oxy-Complex:

  • Light moisturizing. It has a moisturizing rating of 3.3 out of 10.
  • Little anti-wrinkle effect: Credentials Overnight Oxy-Complex 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 Overnight Oxy-Complex has a moisturizing rating of 3.3 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 high humectancy of 6.6 out of 10, primarily due to the high content of Butylene Glycol (est. ≈6.0%).

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, Credentials Overnight Oxy-Complex has a minimal anti-wrinkle rating of 0.1 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Glycolic Acid (est. ≈0.3%),
 highly effective in peelings, yet with below-average anti-wrinkle efficacy when used in leave-on skincare products.
 
Among others, Credentials Overnight Oxy-Complex 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 Credentials Overnight Oxy-Complex is rich (> 3%) in antioxidants, specifically Glycoproteins (est. ≈2.5%).

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.

Butylene Glycol
Est. %6
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.

Salicylic Acid
Est. %0.3
Function
Origin
This effective peeling and anti-inflammatory BHA is used as an anti-acne agent and works by breaking down the junctions between dead skin cells. This results in the peeling of dead skin and the unclogging of pores.
Glycolic Acid
Est. %0.3
Function
Origin

The second most used AHA (after lactic acid) known for its potent exfoliating and smoothing effects. It increases skin cell turnover, which is beneficial for treating acne. When used in peels, glycolic acid has confirmed anti-wrinkle efficacy, though it is less effective in leave-on products like creams and serums.

Lactic Acid
Est. %0.3
Function
Origin
The most popular AHA in skincare and less irritating than glycolic acid. It can be naturally found in sour milk. It is a humectant moisturizing, pH stabilizing, and gently exfoliating ingredient, able to soften dry, cracked, and peeling skin.
Malic Acid
Est. %0.3
Function
Origin
A simple organic alpha-hydroxy acid (AHA) commonly found in unripe fruits. It is more gentle of an exfoliant when compared to the famous and potent glycolic and lactic acids.
Citric Acid
Est. %0.3
Function
Origin
A gently exfoliating AHA that helps to remove the top layer of dead skin cells. In comparison to other AHAs, citric acid has been shown to be one of the least effective. It is also very commonly used as a stabilizing and pH-controlling agent.
Sodium Citrate
Est. %0.3
Function
Origin
A salt of citric acid that has a salty and tart flavor and is used as a fragrance. It is mildly basic, meaning that its addition to a skincare product can adjust the pH upward.
Hydroxyethylcellulose
Est. %0.3
Function
Origin
A naturally-derived thickener that can form clear gel textures without the slimy feeling, unlike some other natural gel-formers.
Sodium Hydroxymethylglycinate
Est. %0.3
Function
Origin
A preservative agent.
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.
Diazolidinyl Urea
Est. %0.3
Function
Origin
A synthetic preservative that is effective against most common bacteria. It is not considered broad-spectrum because it does not act against any type of yeast or mold. It is therefore commonly paired with antifungal preservatives.
Methylparaben
Est. %0.3
Function
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.
Propylparaben
Est. %0.3
Function
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.
