CIRCADIAN SKIN SCIENCE
Welcome to a new era in skincare efficacy. Circadian Skin Science means:
+ Getting better results by applying the right ingredient at the right time of day.
+ Working with the body's natural 24 hour circadian rhythm to deliver precision ingredients to support the skin’s natural processes.
Ingredients delivered to the skin, as it calls for it.
Your body has an internal clock (your circadian rhythm) that tells your skin when to protect, when to repair and when to regenerate. Key skin functions such such as barrier function, cell proliferation, DNA repair, collagen synthesis, hydration barrier function, immune responses, and inflammation all fluctuate based on the time of day.
Different ingredients can have higher efficacy at different times of day
By aligning ingredients with these natural cycles, skincare becomes more intuitive, more effective, and less complicated. Smarter timing. Fewer products. Better results.
Ingredients
RAESO pairs encapsulated actives with refined slow-release systems, allowing each formula to evolve with precision. Performance extends beyond application, unfolding gradually, deliberately, in rhythm with skin.
Time intelligent ingredients are combined with bio-adaptive New Zealand botanicals, shaped by some of the world’s most unforgiving UV landscapes, bring an innate resilience.
Time-responsive by design, RAESO delivers exactly what skin needs, precisely when it needs it.
Ancient wisdom meets cutting-edge biotechnologies
We prioritise hand-harvesting and sustainable practices, ensuring every ingredient is sourced with respect for the environment.
Through biofermentation, nutrients become more bioavailable, allowing skin to absorb and use them more effectively. Cold-extraction preserves heat-sensitive vitamins and minerals, protecting their potency.
The result is enhanced nutrient levels and visibly brighter, smoother, more luminous skin.
Formulated with over 90% naturally derived ingredients, elevated through advanced biotechnology and biomimetic science, RAESO supports skin rather than overwhelming it, helping it function at its best.
By uniting nature’s most resilient plants with modern skin science, RAESO creates high-performance formulas designed to thrive in even the most extreme environments.
SUSTAINABILITY
Sustainability underpins every aspect of RAESO, from sourcing and formulation to packaging and production.
We work exclusively with responsibly produced bioactives chosen for their low environmental impact and natural ability to regenerate. In Aotearoa New Zealand, marine algae is harvested according to Tikanga Māori - an indigenous practice rooted in care, respect and balance.
Our signature pebble vessels, crafted from 20% recycled glass, are fully refillable and designed to be kept. Refills are already available for selected products, with every RAESO formula supported by a refill option soon.
In a fast-moving industry, RAESO favours intention over excess. A simplified protect-by-day, repair-by-night system delivers what skin needs, nothing more.
Our focus is longevity: of skin, of resources, and of the environments that sustain us.
OUR FOUNDER
After two decades in global beauty, returning home to Aotearoa New Zealand shifted Katey Mandy’s perspective.
Raised between Auckland and her family’s rewilding farm near Whangārei, she grew up surrounded by native plants shaped by some of the world’s most intense UV conditions. Their resilience - rich in protective antioxidants - became the foundation of her work.
But over years of formulation and collaboration with leading scientists, another truth emerged: when you apply skincare is as important as what you apply.
Skin runs on a 24-hour rhythm, adjusting, defending, repairing. Its priorities shift throughout the day. When you support that rhythm, pairing ingredients with its changing needs, skin works better, not harder.
Factor time into your routine, and you maximise the power of your skincare.
