La Roche-Posay 10% Pure Vitamin C Anti-Aging Face & Neck Serum reveals sensitive skin's full radiance. As a result, wrinkles look visibly reduced and skin texture and tone are more even and refined. This serum combines concentrated 10% pure vitamin C, salicylic acid and neurosensine for optimal effectiveness while also being suitable for sensitive skin. 10 % Pure Vitamin C, also known as L-ascorbic acid is known for its antioxidant and visible anti-aging properties. Salicylic Acid, known for its effective exfoliating properties, help clear and refine the appearance of pores. Neurosensine helps skin feel soothed. Glycerin helps hydrate skin by absorbing water from the surrounding environment. Hyaluronic Acid (HA), a polysaccharide (carbohydrate polymer) found naturally within the skin, is an effective humectant that can hold a large amount of water to help maintain the skin's moisture. La Roche-Posay Thermal Spring Water contains a unique combination of minerals, trace elements, and a high concentration of selenium, a natural antioxidant. This innovative product provides the skin with both renewing and anti-aging benefits, as it targets wrinkles and fine lines, dullness and lack of luminosity, and irregular skin texture. The light, serum-like texture is easily absorbed, leaving a velvety and non-oily finish on the skin. The ultra-light texture is also suitable for combination skin: At 8 weeks: 79% find that skin's irregularity is less visible. At 4 weeks: 84% find that pores are less visible and tighter.
