Can I use Lactic Acid every day?

Does It Mix engine · how often

Usually not. Most people do best with two or three evenings a week; daily use is a common cause of over-exfoliation.

How to build up

  1. Start 2-3 evenings a week.
  2. Skip it on retinoid nights.
  3. Wear broad-spectrum sunscreen daily: AHAs make skin more sensitive to UV.

FAQ

What should I do if Lactic Acid irritates my skin?

Cut back to fewer days, keep a gentle cleanser, moisturizer and sunscreen, and reintroduce slowly once skin calms down. See a dermatologist if irritation persists.
