Review

Results you may expect from using Peter Thomas Roth Potent-C Power Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Peter Thomas Roth Potent-C Power Serum:

  • Moderate moisturizing. It has a moisturizing rating of 4.1 out of 10.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: Peter Thomas Roth Potent-C Power Serum has a moisturizing rating of 4.1 out of 10.

Is it more humectant or occlusive? This product has relatively comparable levels of humectancy and occlusivity: a moderate humectancy of 5.2 out of 10, primarily due to the substantial concentration of Butylene Glycol (est. ≈4.0%), and a moderate occlusivity of 3.0 out of 10, mainly due to the high content of Caprylyl Methicone (est. ≈3.1%) and C10-18 Triglycerides (est. ≈2.2%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Peter Thomas Roth Potent-C Power Serum has a zero anti-wrinkle rating.

It contains Tetrahexyldecyl Ascorbate, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Tetrahexyldecyl Ascorbate provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not generate the anti-wrinkle rating.

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

Antioxidant benefits

We estimate that Peter Thomas Roth Potent-C Power Serum is rich (> 3%) in antioxidants, specifically Tetrahexyldecyl Ascorbate (est. ≈20.0%), Tocopheryl Acetate (est. ≈3.0%) and Ferulic Acid (est. ≈2.0%).

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.

Ingredients explained

Water
Est. %55
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.
Tetrahexyldecyl Ascorbate
Est. %20
Function
Origin
A lipid-soluble form of vitamin C that is more stable and less irritating than ascorbic acid. According to a recent clinical study, THDA has all the capabilities of regular vitamin C, including anti-wrinkle and anti-pigment activity.
Butylene Glycol
Est. %4
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.

Function
Origin
An antioxidant derivative of tocopherol (vitamin E). It helps to protect cells from free radicals and UV damage through the conversion to active vitamin E in the skin. It is more stable than tocopherol.

A version of plain lecithin that has been saturated with hydrogen atoms. This ingredient can be derived from plants, like soy or sunflower, from egg yolks, or made synthetically. Its major function is to emulsify water and oils.
Propanediol
Est. %0.3
Function
Origin
An excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.
Sodium Hyaluronate
Est. %0.3
