Sigma Beauty was founded in 2009 by Brazil natives, Dr. Simone Xavier and Rene Xavier Filho, a scientist and engineer set on changing the beauty industry. Together, the duo identified a niche in the international beauty market for affordable, high-quality beauty tools. The unstoppable husband and-wife duo used their backgrounds in science to develop and launch Sigma Beauty’s first brush set that instantly captured a cult following and sold out. Sigma Beauty continues to lead the industry in quality, function, and innovation with 60+ patents worldwide and retailers in 70+ countries.
