A veterinarian and scientist, Simone Xavier started Sigma Beauty in 2009 with her husband Rene Xavier Filho. The two noticed a niche in the beauty industry for affordable, high-quality brushes. The power couple used their backgrounds in science to launch Sigma's first brush set. It instantly captured a cult following and sold out. Since then, Simone has dedicated herself to creating solution-driven brushes, makeup, and brush care products of the highest quality. Her drive to better beauty routines for the everyday beauty user is boundless.
