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 Centre 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 ageing research, Dr. Pinnell published more than 200 scientific articles about topical vitamin C, antioxidants, collagen synthesis, and photo-damage 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 honours.
Dr. Pinnell’s skin science research earned him eight patents over the course of his career. 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 have supplemented Dr. Pinnell’s initial patent, one for the formulation-specific application to protect the ingredient 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 provided a firm foundation for all SkinCeuticals antioxidant products.
DR. PINNELL'S RESEARCH
Dr. Pinnell had 100 peer-reviewed publications, including many related directly to the topical antioxidant innovative technologies:
Pinnell, S.R., et al.,Topical L-Ascorbic Acid: Percutaneous Absorption Studies. Dermatol Surg 27:2, 137-142, 2001
SkinCeuticals was the first to discover the exact formulation specifications a topical antioxidant must meet in order to penetrate the skin.
Lin, J.Y., Selim, M.A., Shea, C.R., Grichnik, J. M., Omar, M.M., Monterio-Riviere, N.A., and Pinnell, S.R. J Amer Acad Dermatol 48: 866-74, 2003.
SkinCeuticals' second-generation product marks an important milestone in the development of antioxidant technology. For the first time, it was possible to mix successfully an aqueous antioxidant (Vitamin C) with an oily antioxidant (Vitamin E).
Pinnell, S.R, J Am Acad Dermatol. 48(1): 1-19, 2003.
In order to provide full-spectrum protection against environmentally caused skin damage, it is imperative to use a topical antioxidant daily. This added protection from free radicals has been proven to help prevent premature skin ageing.
Pinnell, S. et al. J Am Acad Dermatol. 59(3):418-25, 2008.
With SkinCeuticals third-generation topical antioxidant, C E Ferulic, it is possible to provide the skin with eight times its natural photoprotection, as well as unprecedented anti-ageing results.
Additional peer-reviewed publications prove the ineffectiveness of other antioxidants - including alpha lipoic acid, ubiquinone, idebenone, and kinetin - in protecting skin from oxidative stress:

In 2013, the Duke University School of Medicine and the Department of Dermatology created The Sheldon Pinnell Centre for Investigative Dermatology to honour Dr. Pinnell’s unwavering commitment to the discovery of new and innovative methods of treating skin diseases and to training the next generation of young investigators. The establishment of the Pinnell Center provides a comprehensive program for investigative dermatology through support for early career investigators with initial funding; support for post-doctoral fellow training; funding for innovative proposals and new projects focused on translational research leading to new therapies for skin disease; and the enrichment of the investigative community through regular seminar series, development of core facilities and laboratories, and support for translational and clinical research.
With a vision to build a world-renowned Department of Dermatology, Dr. Pinnell marked his tenure as division chief from 1982-1997 with bold strategic initiatives, including the recruitment of new clinicians and investigators, establishing new areas of research in immuno-dermatology and connective tissue, as well as initiating new clinical efforts in wound care, laser medicine, dermatologic surgery, and paediatric dermatology. His efforts and those who have come before and after him culminated in the establishment of the Department of Dermatology in 2009, highly regarded today for innovation and excellence in research, clinical care, and training.
The Pinnell Centre serves as an enduring legacy of the faculty, staff and students’ appreciation and gratitude to Dr. Pinnell for his loyalty, mentoring, enthusiastic embrace of academic life, intellectual curiosity and outstanding leadership that has positioned Duke University’s Department of Dermatology as a national and world leader.
