The Resurfacing Retinol Serum by CeraVe is a skincare serum formulated with retinol to provide various benefits to the skin. Retinol helps in reducing the appearance of wrinkles, fine lines, and uneven skin tone, while also promoting skin renewal. However, some users may experience dryness, redness, or irritation when using retinol products. It is advisable to start with a lower concentration and gradually increase usage to minimize potential side effects.
