Skin Cycling
Definition
Skin cycling is a skincare method popularized by dermatologist Dr. Whitney Bowe that involves rotating active ingredients on a nightly schedule to maximize their benefits while minimizing irritation. The classic four-night cycle is: Night 1 — chemical exfoliation (AHA or BHA); Night 2 — retinoid treatment; Nights 3 and 4 — recovery (using only gentle, hydrating, barrier-supporting products). This rotation allows the skin to benefit from potent active ingredients without the overuse that often leads to irritation, dryness, and a compromised barrier. Skin cycling is particularly beneficial for beginners who are introducing actives for the first time, people with sensitive or sensitized skin, and anyone who has experienced irritation from using too many actives too frequently. The cycle can be adjusted based on individual tolerance — some may extend recovery nights, while experienced users might shorten them.
