How to Use

Apply 3-4 pumps onto face, neck, and chest morning + night. 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.
