Want to level up your skincare routine? Beauty experts say you should strategically plan your active ingredients and recovery nights to boost results while minimizing irritation. This concept of cycling through skincare products for success is called "skin cycling," and most individuals follow a four-night schedule that looks something like this: (1) Night 1, exfoliation night. Choose between physical or chemical exfoliation to slough off dead cells and set the stage for the following night. (2) Night 2, retinol night. Retinol is an excellent option for anyone looking to brighten their complexion and reduce signs of aging. (3) Night 3 and 4, recovery nights. On recovery nights, focus on repairing and nourishing your skin barrier and microbiome. This can help your skin bounce back from exfoliating products and retinoids.
