If you know beauty, you know Beautyblender. Since the brand’s launch in 2003, those fuchsia, egg-shaped sponges have become a staple in the beauty industry, thanks to the ingenuity of Rea Ann Silva, Beautyblender’s Latina founder and CEO. Today, the Bethlehem, Pennsylvania-based company is coming off its 13th Allure Best of Beauty Hall of Fame Award and does $100 million to $150 million in annual retail sales.  But you don’t dominate a trend-driven industry for over two decades without encountering a few challenges. Between the pressure to innovate, changes in technology, and knockoffs of her product, Silva has faced her fair share.
