Peter Thomas Roth’s Potent-C Brightening Vitamin C Moisturizer is a daily face cream formulated with a stabilized 20% L-ascorbic acid, a form of vitamin C known for its antioxidant properties. The formula also includes vitamin E and ferulic acid, which work together to help defend the skin against environmental aggressors such as pollution and UV exposure. This moisturizer is designed to support a more even skin tone and reduce the appearance of dullness over time. The lightweight, non-greasy texture absorbs readily into the skin and feels comfortable under makeup or sunscreen. It contains humectants like sodium hyaluronate to provide surface hydration without clogging pores. The product is packaged in an airless pump to help maintain the potency of the vitamin C and minimize oxidation. Suitable for normal, dry, combination, and sensitive skin types, it can be incorporated into both morning and evening skincare routines. For daytime use, it should be followed by a broad‑spectrum sunscreen, as vitamin C may increase photosensitivity. This moisturizer does not contain synthetic fragrances or dyes, which makes it a gentle option for those with reactive skin. The formula is free of parabens, sulfates, and phthalates. Regular application may help support the skin’s natural radiance while providing basic hydration needs. Individuals concerned with loss of firmness, fine lines, or uneven texture may find the antioxidant blend beneficial as part of a broader skincare regimen. The cream is best stored in a cool, dry place away from direct sunlight to preserve ingredient stability. This product is not intended to treat or prevent medical conditions; it serves as a cosmetic aid for maintaining skin appearance and comfort.
