How often should you exfoliate?

Exfoliating your skin can significantly improve its texture and appearance. According to Michelle Wong, a cosmetic chemist and skincare specialist, the frequency of exfoliation depends on the type and strength of exfoliant you use. For chemical exfoliants, it's advisable to start once a week if you are new to them. Gradually, you can increase the frequency. Most individuals may benefit from exfoliating two to three times a week. It is crucial, however, not to over-exfoliate, as this can damage your skin's protective barrier, causing stinging and increased sensitivity to other products 1.

It's also worth noting that chemical exfoliants help by dissolving the connections between dead skin cells, promoting even shedding. Common chemical exfoliants include glycolic acid, lactic acid, salicylic acid, and mandelic acid 2. Always follow the specific product's instructions and be mindful of your skin's response to avoid over-exfoliation.
