The Circadia Philosophy
This brand is founded on the science of chronobiology – the study of how biological rhythms affect our health. Dr. Peter T. Pugliese, a renowned physician and researcher, developed Circadia to honor the skin's natural repair cycles. The result is a line of Circadia facial products that nourish, protect, and renew in harmony with the body's internal clock.

Free of parabens, harsh sulfates, and synthetic dyes.

A circadian rhythm, or circadian cycle, is a natural oscillation that repeats roughly every 24 hours

With formulas that support the skin during the day (defense mode) and night (repair mode), this brand delivers results that go beyond surface-level improvements. From cutting-edge peptides to powerhouse antioxidants like vitamin C, these products are smart, synergistic, and suitable for a wide range of skin concerns.
