The Science of Circadian Rhythms
At Circadia Australia, we proudly bring you a skincare philosophy backed by decades of scientific research, formulation expertise, and a deep understanding of the body’s natural circadian rhythms. Our professional-grade skincare solutions are designed to elevate treatment outcomes, support skin health and empower professionals with cutting-edge tools, education and support.
A Scientific Legacy Led by Innovation
Circadia was founded on the pioneering work of Dr. Peter T. Pugliese, a visionary in skin science whose research into the role of circadian rhythms in skin function transformed the way we understand skincare. Today, Circadia remains a family-owned business, with Dr. Pugliese’s legacy carried forward through advanced formulations that align with the body's natural biological clock to support optimal skin health and function.
The Power of Circadian Rhythms in Skincare
The name Circadia comes from the Latin phrase “circa diem,” meaning “around the day.” Circadian rhythms are 24-hour cycles that influence everything from hormone release to cellular regeneration, including the skin’s ability to protect, repair and renew itself.
When these rhythms are disrupted by stress, poor sleep, blue light exposure, or environmental factors, skin can experience premature ageing, inflammation and decreased efficacy of topical products. Circadia’s formulations are developed to work with these natural cycles, offering protection during the day and supporting cellular repair at night through chronobiological science.
Advanced Technologies and High-Performance Ingredients
Circadia’s commitment to innovation is evident in its use of sophisticated ingredients and delivery systems that enhance skin results while maintaining a clinical clean profile; free from parabens, artificial fragrance and SLS.
Plant Stem Cell Technology
Circadia uses plant-based stem cell extracts to target inflammation, oxidative stress, and premature aging. Key actives include:
- Malus Domestica (Apple Stem Cell) – Supports skin longevity and reduces wrinkle depth
- Edelweiss – Protects against environmental stress
- Gardenia – Hydrates and strengthens the skin barrier
- Grape Stem Cell – Offers powerful antioxidant protection
- Lilac Stem Cell – Ideal for balancing oily, acne-prone skin
Second-Generation Vitamins
Stabilised vitamin derivatives in Circadia formulations offer greater efficacy with minimal irritation:
- Vitamin A (Retinol & Retinyl Acetate) – Smooths skin and improves texture
- Vitamin B (Niacinamide & Panthenol) – Brightens, calms, and strengthens the skin
- Vitamin C Derivatives – Brighten, protect, and support collagen synthesis
- Vitamin E (Tocopherol & Tocotrienol) – Neutralises free radicals and supports recovery
