To reduce your risk of irritation, the Cleveland Clinic recommends using AHA products every other day. As your skin gets used to them, you can then start applying AHAs every day.
Also use extra caution when going out in the sun. The peeling effects of highly-concentrated AHAs may make your skin more sensitive to UV rays for up to one week after use. You should wear sunscreen daily and reapply more frequently to prevent sunburn.
