Vitamin C is an excellent brightening agent as it helps reduce melanin production (dark spots) while also providing antioxidant benefits to calm sensitive skin and decrease inflammatory signals (source: The Roles of Vitamin C in Skin Health, 2017).

RELATED:

The Potent-C collection is based on a vitamin C derivative called Tetrahexyldecyl (THD) Ascorbate, a stable and oil-soluble compound, that gives the overall formula a slightly thicker texture.

In particular, Potent-C Targeted Spot Brightener includes 10% THD Ascorbate to brighten dark spots, along with antioxidant teammates 3% Vitamin E and 2% Ferulic Acid that work synergistically to improve uneven tone, promote a clearer and healthier complexion, and prevent skin damage (sources: Topical L-Ascorbic Acid: Percutaneous Absorption Studies, 2001 and UV Photoprotection by Combination Topical Antioxidants Vitamin C and Vitamin E, 2003).

(in fact, this formulation is likely inspired by SkinCeuticals C E Ferulic, which uses 15% L-Ascorbic Acid, or pure vitamin C, along with 1% Vitamin E and 0.5% Ferulic Acid)

Peter Thomas Roth also included Gwennis (Algae) Extract and Angelys (Angelica Root) Extract for additional skin lightening benefits (based on a 12 week in vivo study by Peter Thomas Roth).

Finally, customer reviews have been relatively good, with reviews fluctuating between “it worked!” and “I saw no results!” This product helped many users clear up brown spots and post-acne marks. On the other hand, some complained about the smell (due to no fragrance) and high price.

My Verdict: If you have troublesome dark spots or post-acne marks that refuse to part ways, the Potent-C Targeted Spot Brightener can help you “break up” with them for good.
