The No7 Radiance+ 15% Vitamin C Serum is a daily-use facial serum formulated with a 15% concentration of pure vitamin C, a well-known antioxidant that supports skin brightness and even tone. This serum is designed to help re-energize the skin's appearance by promoting a more radiant, glowing complexion over time with consistent use. The vitamin C content works to help defend against environmental stressors such as pollution and UV exposure, which can contribute to dullness and uneven skin texture.

The formula is intended for most skin types, including those with normal, combination, or slightly dry skin. It has a lightweight, fast-absorbing texture that layers well under moisturizer or sunscreen without feeling heavy or sticky. The serum is packaged in a 0.84 oz (25 ml) bottle with a dropper for controlled application.

Key aspects of the formulation include a focus on stability and efficacy, with the vitamin C being incorporated in a way that reduces the risk of oxidation over time. This product is not a clinical treatment for specific skin conditions, but rather a maintenance serum for those seeking to add a daily antioxidant step to their skincare routine.

No7 is a well-established British skincare brand known for its research-backed products. The Radiance+ range targets dullness and lack of luminosity, and this serum fits into that category by offering a straightforward, vitamin C-based approach. For best results, it should be applied to clean, dry skin in the morning or evening, followed by sunscreen during the day to maximize the protective benefits of the antioxidant.
