Peter T. Pugliese, M.D., world-renowned skin physiologist, passed away on Jan. 15 at the age of 94. According to his obituary, he served in the U.S. Marine Corp during World War II, and in the Korean War as a Sargent in the U.S. Army. Pugliese began his career as a physician in 1957, and since then was the inventor of 13 patents and an authority, innovator, and entrepreneur in the fields of cosmetic chemistry, ingredient formulation, and precision skincare. Beginning in the late 1970s, he became a fixture at the world’s leading gatherings of ingredients, formulation, and cosmetic science events, including the Society of Cosmetic Chemists, the American Academy of Dermatologists, the International Society for Bioengineering and the Skin, the Society for Investigative Dermatology, the American Association for the Advancement of Science, and more. In 1996, he was awarded the Maison G. de Navarre Medal Award, the Society of Cosmetic Chemists's highest honor. Nearly 50 years after beginning his career as a physician Pugliese founded Circadia by Dr. Pugliese, a skincare system based on the circadian rhythms of the body and the science of chronobiology. Circadia became the first product manufacturer to introduce topical ingredients proven to work with the body’s natural circadian rhythms.
