Skin cycling is the latest skincare trend that recommends using an exfoliant one day, a retinol the next, followed by two days of moisturizing with skin soothing ingredients to repair the skin’s moisture barrier. While simplifying the steps of your routine can be beneficial, doubling down on exfoliants can also traumatize your skin. Skin has memory and continued cycling through multiple exfoliants can cause your skin to remember that trauma and leave your face vulnerable to inflammation, acne, and accelerated signs of aging.
