Sunday Riley

Sunday Riley launched her own line in 2009, that experience gave her an advantage over other product-peddling aestheticians and makeup artists. "I knew about a lot of little secrets in the industry," she said. "All ingredients are not created equal. When you go and buy chemicals for your skin care products, you can buy different grades, and that completely affects the products." She added, "The person selling it at Sephora probably has no idea."
