Paula Begoun is known worldwide as The Cosmetics Cop for her role as a consumer advocate and investigative researcher on skin care and makeup. From an early age, Paula struggled with skin issues including acne and debilitating bouts of eczema. Frustrated by the ineffective treatments and products at the cosmetic counters and from dermatologists, Paula started examining the scientific research herself. Soon, she solved her skin problems by following published research on how skin works and which cosmetic ingredients really work. Determined to help others find the best products for their skin, Paula has written 19 books on cosmetics and is one of the best-selling beauty authors of all time. Paula lives in Seattle surrounded by her family and dogs. Bryan Barron has been working closely with Paula for 12 years. He spent many years working for various cosmetic lines in the retail sector, as a makeup artist, educator, and manager. His first project with Paula was the fifth edition of Don't Go to the Cosmetics Counter Without Me. Since then, he has played an integral role in subsequent editions of that book along with The Beauty Bible. Bryan also served as co-writer and editor of Paula's former newsletter Cosmetics Counter Update. He currently manages and writes content for the Beautypedia and Paula's Choice Web sites and continues to evaluate the latest research with Paula and the Paula's Choice Research Team. Desiree Stordahl is an ongoing contributor to articles concerning skin care and makeup at CosmeticsCop.com and has been trained under the personal guidance of Paula. As part of the Paula's Choice Research Team, Stordahl's role includes evaluating cosmetic ingredients, investigating the physiological effects of skin-care products, and writing product reviews.
