Chameleon Cover-Up
The ultimate multitasker, this concentrated yet blendable liquid pigment can act as a concealer or as a full-cover foundation. It also mixes well with other makeup to adjust coverage, and face and body products to create a custom tint that hides whatever you'd like (we tested with serums, lotions, creams, and even oils).
