Step 1: Gently sweep across clean face for 10-20 seconds. Avoid eye area, lips and nostrils. Mild tingling is normal and temporary.
Step 2: Allow to dry before following with moisturiser and sunscreen.
Tips: May be used daily. Do not layer any leave-on products containing glycolic acid, lactic acid, citric acid or other AHAs after using.
Wear sunscreen during the day to avoid any increase in sun sensitivity.
