Start with a clean, dry face after cleansing and toning. Apply 2–3 drops of the serum evenly over the face or to targeted areas. Gently pat until fully absorbed. Follow with a moisturizer to lock in hydration. Use once daily in the evening or twice daily if your skin tolerates it well. Always apply sunscreen during the day when using azelaic acid.

Tip: For sensitive skin, begin with once-daily use and gradually increase frequency as needed.
