Step 1 - Serum: Cleanse face thoroughly and pat dry. Apply 2-3 drops of serum to fingertips and gently pat onto face and neck — do not rub, patting ensures better absorption. Allow serum to fully absorb for 60 seconds before applying moisturizer. Always follow with a broad-spectrum SPF 50 sunscreen in the AM. For visible results use daily — most users see improvement in skin radiance in 2 weeks and dark spot reduction in 3-4 weeks. Step 2 - Sunscreen: Apply generously on face, neck and all sun-exposed areas as the last step of your morning skincare routine. Apply at least 15 minutes before going outdoors. Use a coin-sized amount for the face alone. Reapply every 2 hours when outdoors. Use daily — even on cloudy days and indoors near windows as UVA rays penetrate glass.
