Allies of Skin Vitamin C 20% & Citrus Cells Light-Reflecting Serum is a highly effective serum designed as a daily energy dose for dull skin or skin affected by external factors. Its advanced, anhydrous formula delivers fast and visible results, supporting a more radiant, even-toned, and smoother complexion from the very first application. The foundation of the formula is 20% 3-O-Ethyl Ascorbic Acid, a modern and stable form of vitamin C (an ethylated derivative of ascorbic acid, better tolerated and more resistant to oxidation), which helps improve skin firmness, reduce dullness, and support natural renewal processes. This form of vitamin C is active on the skin and can be used daily, even in the morning under sunscreen. The formula is further enhanced by the Citrus Cells & Glutathione Complex (a plant cell extract from citrus fruits combined with glutathione, a natural antioxidant), which helps protect the skin from oxidative stress and supports a more even complexion. Additionally, ergothioneine, dimethylmethoxy chromanol, and tocopherol (vitamin E) provide advanced antioxidant protection, working synergistically to shield the skin daily from environmental pollution and other stressors. A standout feature is the anhydrous diamond powder base, which enhances formula stability and creates an optical light-reflection effect without visible particles or a heavy feel. The concentrated texture spreads evenly, absorbs without leaving a greasy film, and leaves a radiant finish. The serum is suitable for all skin types and daily use, even under makeup. Cruelty-free and vegan.
