How to Use

Bright Skin Like A Derm Duo

Apply 3-4 pumps onto face, neck, and chest morning + night. To refill, twist off the top of the pump, removing it from its glass bottle. Keep the reusable top pump. Swap in a new refill, then put the pump back into the glass tube. If you’re new to vitamin C, leveling up the strength of your vitamin C, or if you have sensitive skin, patch test on the inner forearm or side of the neck first. Start using once a day in the morning before working your way up to twice a day, and layering with other skincare actives.
