Most people should exfoliate 2 to 3 times a week, though the right frequency depends on your skin type and which acid you're using, and over-exfoliating is a far more common problem than under-exfoliating.
By skin type
- Oily or acne-prone: up to 3 to 4 times a week with a BHA, since oilier skin generally tolerates exfoliation better.
- Dry or sensitive: 1 to 2 times a week, favoring a gentle PHA over stronger acids.
- Combination: 2 to 3 times a week, adjusting based on how the T-zone versus cheeks respond.
Frequently asked questions
How do I know if I'm over-exfoliating?
Tightness, redness, increased sensitivity to other products, or a shiny, over-polished look are all signs to cut back immediately.
Can I exfoliate every day?
Generally no, even for oily skin. Daily exfoliation removes skin cells faster than they can be replaced, which weakens the skin barrier over time rather than improving texture.
Should I exfoliate at night or in the morning?
Night is generally safer, since exfoliation increases sun sensitivity and gives skin time to recover before UV exposure the next day.
