Brand from United States: YEOUTH. How to use: Use only at night. Cleanse face thoroughly. For best results, first spritz YEOUTH Balancing Facial Toner on face. While toner is still damp, apply a pea-sized amount of YEOUTH 2.5% Retinol Serum to face and neck area. If also using YEOUTH Hyaluronic Acid Plus Vitamin C and Tripeptide-31, OR YEOUTH Hyaluronic Acid Cream, apply both products back to back while your face is still wet. It does not matter in which order they are applied. Allow to absorb into skin. Follow with a YEOUTH Anti-aging Moisturizer. Always apply sunscreen to treated areas if going outside. Use every other night when starting to determine skin sensitivity. If skin irritation is not present, continue to use every night.
