This Tatcha Violet-C Radiance Mask ($68) is in my regular mask rotation because it has two types of brightening vitamin C inside to take on hyperpigmentation. There's a water-soluble one that absorbs (and works) quickly and then an oil-soluble one that helps my complexion become more even and less red over time. It also helps with any dryness, thanks to a 10-percent AHA-blend to eliminate dead skin cells on the surface.
