Review

Results you may expect from using Paula's Choice C15 Vitamin C Super Booster:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Paula's Choice C15 Vitamin C Super Booster:

  • Moderate moisturizing. It has a moisturizing rating of 4.8 out of 10.
  • Some anti-wrinkle efficacy: Paula's Choice C15 Vitamin C Super Booster has an anti-wrinkle rating of 2.5 out of 10 so you may expect some, although limited, effect on wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: Paula's Choice C15 Vitamin C Super Booster has a moisturizing rating of 4.8 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.2 out of 10 and a very high humectancy of 9.4 out of 10, primarily due to the high content of Glycerin (est. ≈4.0%) and Ethoxydiglycol (est. ≈3.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Paula's Choice C15 Vitamin C Super Booster has a slight anti-wrinkle rating of 2.5 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈6.0%), 
 or Vitamin C, a popular anti-wrinkle ingredient, yet with average efficacy confirmed by only one study.
 
Among others, Paula's Choice C15 Vitamin C Super Booster also contains Palmitoyl Tripeptide-5, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Palmitoyl Tripeptide-5 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 Paula's Choice C15 Vitamin C Super Booster 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.
