The new matte definition brush by blacklUp reinvents the way you apply foundation. With its distribution of hairs that is three- to ten-times greater than a classic brush, this brush spreads the formula evenly for a natural, blurring second-skin make-up result. A complete multi-tasker, it can be used will all formulas. Pick up some formula by laying your brush flat onto it and making small circular movements. Then apply the formula, sweeping outwards from the middle of the face.
