Collection: Circadia by Dr. Pugliese

Circadia was founded by the world-renowned and globally recognized Dr. Peter T. Pugliese. Dr. Pugliese was the first physician of his caliber to dedicate decades of research to understanding the skin and its ability to deliver clinical and relevant information on product development. Before the launch of Circadia in 2001, Dr. Pugliese spent 30 years developing and manufacturing products for major brands in the industry.

He also conducted the first clinical study on Copper peptide, topical Vitamin E, and Beta Glucan, advancing our industry to where we are today. Dr. Pugliese is a world-renowned author of aesthetics textbooks, including Advanced Professional Skincare Medical Edition, The Physiology of the Skin editions I, II, and III, and conducted numerous clinical studies, dedicating his life to the advancements in skin health, formulary achievements, and education of skin physiology.

Dr. Pugliese has won nearly every award from The Society of Cosmetic Chemists, including the highest honor and recognition, the Maison De Navarro Award, for his technical contributions to cosmetic chemistry.   

We strongly recommend using the products within the line to achieve ultimate results. Mixing the products might have an adverse reaction.
