How often should I exfoliate my face?

There is no single schedule that suits everyone. The product, your other treatments, and your skin's response matter more than a daily or weekly rule. I would rather use the lowest frequency that creates progress while the skin stays comfortable than chase a preset number of exfoliation days.

Exfoliation frequency should follow tolerance, not a calendar

My approach is to start cautiously with one suitable product and adjust only while the skin stays comfortable. Stinging, new dryness, or redness means it is time to reduce or pause.
