This hyperpigmentation-safe serum visibly reduces stubborn discoloration, post-blemish marks, scars, and spots for all ethnicities and skin shades. Gentle enough for daily use, it produces visible results in as little as two weeks. Faded has a sulfur-like smell. Apply a thin, even layer onto cleansed, dry skin before moisturizing. Gently massage into skin until serum has been absorbed. Use 1 time a week to start and work your way up to daily use. Use sun protection during the day, and moisturize well when using.
