Sure, mineral make-up is fun, easy to use, and allows you create stunning looks ranging from natural to glamorous, but what makes PowderColors different? PowderColors is a blend of pure, uncoated mineral pigments and oxidized mica, free from unnecessary fillers and preservatives. The popular department store brands contain talc and bismuth oxychloride - cheap fillers that can wreak havoc on your skin. Bismuth oxychloride is a synthetically-produced metal that can get into pores and cause irritation.
