NARS Cosmetics Radiant Creamy Concealer Medium 1 Custard M1 Brand New Full Size NWT. This concealer is a classic for a reason: it brightens under eyes, covers blemishes, and smooths everything out with a radiant, skin-like finish that never looks heavy. The creamy formula blends like a dream with both fingers and a brush and gives you that “I slept, I’m hydrated, I have zero problems” look—even if none of that is true.
