Niacinamide Face Serum Purity Vision Bio Niacinamide Serum

Apply a few drops of the serum to clean, toned skin in the morning and/or evening. Follow with a facial oil or cream from PURITY VISION, using gentle massaging motions. For a more intensive effect, we recommend combining this serum with other PURITY VISION serums. When using multiple serums, allow each one to absorb for a few minutes before applying the next. It's best to start with a smaller amount of serum and gradually increase usage over time. TIP: For a cooling effect, store the serum in the refrigerator.
