Every day? Once a week? The answer depends on one thing.
A simple rule based on your skin type. No guessing.
The simple rule
By skin type:
- Oily/combo: 2-3x per week (AHA or BHA)
- Normal: 1-2x per week (AHA preferred)
- Dry: 1x per week (lactic acid — gentlest AHA)
- Sensitive: 1x every 10 days or skip entirely
The #1 sign you're over-exfoliating: your moisturizer stings. Stop all exfoliation for 2 weeks and rebuild.
