MDAiRE™'s RXR Retinol Anti-Aging Serum helps promote cell turnover to diminish the appearance of fine lines, wrinkles, uneven skin tone, and blemishes. Our active retinol is encapsulated in a solid lipid, resulting in an anti-inflammatory and anti-irritant formula, which can be used every morning and evening. Using Retinol can make skin sensitive to the sun and UV damage because it is a strong exfoliant.
