RMS Beauty "Un" Cover-Up is unlike other concealers that are heavy and drying to skin. "Un"-Cover-Up is formulated to reveal and enhance healthy skin. Use as a concealer or light foundation where needed to give subtle, flawless, even coverage. For a matte look, set with powder. There is no need to moisturize or prime normal skin, simply apply sparingly with fingers over t-zone area or where extra coverage is needed. "Un" Cover-Up melts into the skin so the colors adjust themselves to your skin tone.
