Sculpt cheeks like a pro with this angled powder brush, shaped to expertly blend blushes and bronzers for the perfect contour. Dermatologist Recommendation: “Your brushes harbor leftover makeup, bacteria and oils. This can cause breakouts, infections and or irritations, especially around the delicate eye area. Change out your brushes every three weeks or clean every two weeks by swishing them in warm water and shampoo, rinse and let dry”   ~Dr. Howard Sobel, Founder of SOBEL SKIN Dermatologist and Dermatologic Surgeon at Lenox Hill Hospital
