BRAND STORY
CIRCADIA
Science-Based Skincare Rooted in Skin Physiology
Circadia was founded by Dr. Peter T. Pugliese, a physician, researcher, educator, and one of the most respected names in professional skincare. Long before evidence-based skincare became popular, Dr. Pugliese was studying how skin functions at the cellular level and teaching estheticians the science behind healthy skin. His textbooks and educational work helped shape modern esthetics as we know it today. (CIRCADIA)
The name Circadia comes from the concept of circadian rhythms, the body’s natural 24-hour biological clock. Circadia’s philosophy is simple: protect the skin during the day and support repair and regeneration at night. Their formulas are designed to work in harmony with the skin’s natural rhythms rather than against them. (CIRCADIA)

Why I Choose Circadia
While I am passionate about Korean skincare, Circadia remains one of my favorite professional skincare lines because of its strong scientific foundation and results-driven formulations.
What I appreciate most is that Circadia focuses on skin health first. Many common skin concerns including premature aging, dehydration, sensitivity, acne, rosacea, and hyperpigmentation are connected to inflammation and barrier dysfunction. Circadia’s approach supports healthy skin function while delivering visible results.
The brand combines advanced cosmetic science with carefully selected botanicals, peptides, vitamins, antioxidants, and barrier-supportive ingredients. Their formulations are designed to help the skin perform at its best while supporting long-term skin health. (The Skin Studio)
