Review

Results you may expect from using Credentials Glycolic Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Credentials Glycolic Serum:

  • Light moisturizing. It has a moisturizing rating of 3.6 out of 10.
  • Little anti-wrinkle effect: Credentials Glycolic Serum has an anti-wrinkle rating of 0.9 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.
  • Soothing: Credentials Glycolic Serum contains a high concentration of soothing ingredients, which may help to reduce irritation and calm the skin.
  • Antioxidant protection.

How moisturizing is it?

Lightly moisturizing: Credentials Glycolic Serum has a moisturizing rating of 3.6 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.8 out of 10 and a high humectancy of 6.3 out of 10, primarily due to the high content of Aloe Barbadensis Leaf Juice (est. ≈6.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Credentials Glycolic Serum has a minimal anti-wrinkle rating of 0.9 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Glycolic Acid (est. ≈3.0%),
 highly effective in peelings, yet with below-average anti-wrinkle efficacy when used in leave-on skincare products.
 
Among others, Credentials Glycolic Serum also contains Retinyl Palmitate, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Retinyl Palmitate 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 Glycolic Serum is rich (> 3%) in antioxidants, specifically Aloe Barbadensis Leaf Juice (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.

Skin soothing

Based on the ingredient list analysis, Credentials Glycolic Serum is rich (> 5%) in soothing ingredients, particularly Aloe Barbadensis Leaf Juice (est. ≈6.0%).

When applied to the skin, compounds of soothing ingredients, such as triglycerides, phospholipids, fatty acids, phenolic compounds, and antioxidants, work together to soothe the skin through various mechanisms: reducing inflammation, promoting wound healing, repairing the skin barrier, and providing antimicrobial and antioxidant activities.
