After cleansing and toner, apply 2–3 drops to the face and gently pat in until the serum is absorbed. Then finish with a moisturizer. Do a patch test before the first use and start slowly – a brief tingling is normal at this concentration. Always use sun protection in the morning. Store the serum in a cool, dark place, as vitamin C is light-sensitive.
