Aveeno Positively Radiant Vitamin C Serum is a daily face serum designed to deliver glowing skin in 1 week, even for sensitive skin. This vitamin C serum helps brighten dull-looking skin, smooth texture, and visibly even skin tone while remaining gentle enough for daily use. Powered by antioxidant oat, Vitamin Cg, and niacinamide, this formula delivers greater antioxidant properties than 15% pure vitamin C*. Antioxidant oat helps soothe skin and defend against environmental stressors, Vitamin Cg, a stabilized Vitamin C derivative, helps boost radiance, and niacinamide helps smooth and even skin tone. After 1 week, this serum leaves skin looking brighter and improves the look of skin texture. With continued use, skin appears more refined, radiant, and balanced with clinically-proven 48-hour hydration. This lightweight vitamin C facial serum absorbs quickly, layers well under makeup, and is non-greasy. The fragrance-free and non-comedogenic formula is designed for and tested on sensitive skin. In a consumer perception study, 93% agreed the formula is non-irritating**, and 86% reported improved dull-looking skin**, and 87% agreed it leaves skin with a natural glow**. Use daily after cleansing and before moisturizing. Follow with a SPF in the morning as part of a simple skincare routine.
