When (and how) to use Bright Icon Vitamin C + E + Ferulic Serum by e.l.f. cosmetics

After you wash your face and before you apply your moisturizer each morning, apply Vitamin C Serum to a clean face and neck as part of your skincare routine (don't forget to always wear SPF, too). After using, store in a cool, dark place. If you are new to vitamin C, patch test and build up tolerance.
