OxygenCeuticals Serum 12 is a gentle antioxidant formulation containing 12% pure vitamin C and vitamin E, designed to support skin brightness and even tone. This serum is intended for individuals with sensitive skin, offering a mild approach to vitamin C application without compromising on stability or efficacy. The formula combines L-ascorbic acid, a direct form of vitamin C, with tocopherol, a form of vitamin E, to help neutralize free radicals and reduce the appearance of environmental damage over time.

The concentration of 12% pure vitamin C is selected to provide noticeable benefits for skin radiance and texture improvement while minimizing the risk of irritation common in higher-strength products. Vitamin E works synergistically to enhance antioxidant protection and support moisture retention, contributing to a smoother and more resilient skin surface. The serum is free from unnecessary additives such as fragrance, alcohol, and essential oils, making it suitable for reactive or easily irritated skin types.

With a lightweight, non-greasy texture, the serum absorbs quickly and can be applied under moisturizer or sunscreen as part of a daily skincare routine. It is packaged in a 30ml (1.01 fl.oz) amber glass bottle to protect the active ingredients from light degradation. The formula is ideal for those seeking a straightforward, effective antioxidant serum that prioritizes skin comfort and gradual improvement in tone and radiance, without reliance on aggressive exfoliants or synthetic brighteners. Suitable for daytime use, it pairs well with broad-spectrum sunscreen for enhanced protection against photoaging.
