La Roche-Posay Pure Vitamin C10 Serum is a dermatologist-recommended anti-aging serum containing 10% pure vitamin C, salicylic acid, and neurosensine. This lightweight formula helps reduce wrinkles, brighten skin tone, and protect against environmental damage while being suitable for sensitive skin. This serum should be applied in the morning on face and neck, avoiding the eye area. For best results, use in combination with SPF protection. The formula has a light, fast-absorbing texture that provides a non-greasy, velvety finish, making it an excellent makeup base. While the serum may naturally turn yellow when exposed to air due to vitamin C oxidation, this does not affect its efficacy. La Roche-Posay is recognized as the #1 dermatologist-recommended skincare brand worldwide.
