After cleansing, saturate a cotton pad and gently sweep across the entire face and neck, avoiding the immediate eye and lip areas. Alternatively, dispense a few drops into clean palms and pat lightly into the skin until absorbed. Use morning and evening. Always apply a broad‑spectrum sunscreen (SPF 30 or higher) during the day, as AHAs and BHAs increase sun sensitivity. If you are new to acid exfoliation, begin with once‑daily application in the evening and gradually increase to twice daily as your skin builds tolerance.
