Product Summary
"Peter Thomas Roth - Potent-C Niacinamide Discoloration Treatment" is effective for: Anti-aging, Evens skin tone, Moisturizing and Anti-blemish
Ingredient callouts
- A good concentration of Niacinamide (5.50% - 6.70%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
- Humectants (glycerin 0.30% - 0.50%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

What does the product description say?
Peter Thomas Roth's Potent-C Niacinamide Discoloration Treatment is an intensive brightening treatment with Vitamin C and Niacinamide that helps reduce the look of discoloration, dark spots and post-acne marks.
Source: Ulta
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: resveratrol.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production
Helps neutralize free radicals in skin and might help reduce fine lines and wrinkles, as well as even out the skin tone
Being a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.
A great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals
Anti-blemish
This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.

Evens skin tone
What does the product description say?
Potent-C Niacinamide Discoloration Treatment
Source: From product name
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: alpha-arbutin, kojic acid, niacinamide, tranexamic acid
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: resveratrol.
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

Moisturizing
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, caprylyl glycol.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, dimethicone.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide
