To capitalize on the Blush Brush trend, the direct play is e.l.f. Beauty, Inc. (NASDAQ: ELF), which designs and sells a wide range of makeup brushes including blush brushes. For broader exposure, consider Ulta Beauty (NASDAQ: ULTA) as a leading retailer of both drugstore and prestige brushes, or Estée Lauder Companies (NYSE: EL) and L'Oreal (LRLCY) which own multiple makeup brands that rely on brushes for application. A global angle can be gained through Shiseido (SSDOY), a major beauty group with an extensive brush assortment. Entrepreneurially, you could launch a sustainable niche blush-brush line or a DTC brand with social-media marketing to capture share in the growing makeup-tools segment.
