About
MAC Lightful C 2-in-1 Tint and Serum with Radiance Booster comes in a dual-chamber bottle, but, unlike the most dual-formula products, each of its treatments should be used separately. The gel-like serum should be used overnight, while the tinted serum is intended for daily use. Both formulas are tailored to resolve different skin concerns, from dehydration, uneven skin tone, to dark spots and hyperpigmentation.
