The company is said to have been launched in response to Paul Thomas Roth’s inability to find effective skincare products for his particular skincare concerns. Today, the company makes a huge array of beauty and wellness products.
How Does Peter Thomas Roth Potent-C Power Serum Work?

Peter Thomas Roth Potent-C Power Serum Ingredients: Are They Safe & Effective?
Now let’s take a look at the active ingredients in Peter Thomas Roth Potent-C Power Serum:
Ferulic Acid
Ferulic acid is an ingredient that may hold several benefits for skin health such as improved elasticity, fortifying the skin’s natural hydration barrier, finer texture, and more. As highlighted in the Mad Hippie Vitamin C Serum Review, it is especially beneficial when paired with Vitamin C, as it enhances the serum’s effectiveness by stabilizing it and increasing resistance to environmental damage.
The Journal of the American Academy of Dermatology has stated in one of their studies that:
Studies reported improved skin erythema, hyperpigmentation, hydration, elasticity, texture and density among those treated with ferulic acid compared with controls
Vitamin E
In most studies that have been conducted on vitamin E’s effects on the skin, it has been found that these antioxidants can help protect the skin from common signs of photoaging from UV rays, and reduce the skin’s susceptibility to irritation and inflammation. However, more studies are needed to confirm these claimed effects.
Additionally, Vitamin E is known for its ability to promote skin hydration and improve the skin’s overall texture by enhancing moisture retention.
Panax Ginseng Root Extract
Panax ginseng, also known as Korean ginseng or red ginseng, has been observed in some studies to help suppress some of the inflammatory markers that are common in most skin types. The National Institutes of Health has stated in a report that:
KRG (Korean Red Ginseng) water extract can significantly improve skin conditions, and can also suppress the expression of inflammatory regulators.
THD Ascorbate
THD Ascorbate is a form of vitamin C that is claimed to be more stable than most forms of this vitamin. The National Institutes of Health has reported that preliminary studies suggest that this ingredient may help improve the structural integrity of the skin but further investigation is needed to elucidate the method of action.
Glycerin
Glycerin, sometimes referred to as glycerol, is an additive that is very common in skincare and beauty products. For the most part, it is used to improve the hydration barrier of the skin. It may also help reduce the risk of chronic skin-drying conditions according to some clinical studies.
