Distinguished Professor, Collagen Chemist and Dermatologist
A distinguished member of the Duke University Medical School faculty for almost 40 years, Dr. Pinnell was a professor of dermatology, held the title of J. Lamar Callaway Professor Emeritus of Dermatology, and also served as Chief of Dermatology at Duke University Medical Center for 15 years. At Duke, he trained physicians from the United States and abroad both as dermatologists and research scientists. With almost four decades of experience in skin cancer, skin disease, and skin aging research, Dr. Pinnell published more than 200 scientific articles about topical vitamin C, antioxidants, collagen synthesis, and photodamage in peer-reviewed dermatology journals.
Dr. Pinnell received his Medical Degree from Yale University, conducted his medical internship and residency at the University of Minnesota Hospital in Minneapolis, Minnesota, and completed his dermatology training at Harvard University and Massachusetts General Hospital in Boston, Massachusetts. Dr. Pinnell conducted his research training as a collagen chemist at both the National Institutes of Health in Bethesda, Maryland and also the Max Planck Institute for Biochemistry in Munich, Germany. Dr. Pinnell earned his Bachelor of Arts degree in Chemistry at Duke University, where he graduated with Phi Beta Kappa academic honors.
Dr. Pinnell’s skin science research has garnered him eight patents over the past three decades. The most important patent in SkinCeuticals history pertains to “A Stable Solution of L-Ascorbic Acid (Vitamin C).” The formulation standards put forth in this study are now known as the Duke Antioxidant patent. Three additional patents supplement Dr. Pinnell’s initial patent, one for the formulation-specific application to protect the combination used in Skin Firming Cream and Eye Cream; another to protect the combination used in SkinCeuticals C+E skincare products; and a third to protect the formulation used in SkinCeuticals phloretin skincare products. Together, these patents provide a firm foundation for all SkinCeuticals antioxidant products.
