You know Raaie. Now meet Raeso - the same science-led spirit with a new name that encompasses everything about the brand.
In 2026, the New Zealand-born brand evolves into Raeso - Circadian Skin Science™, pioneering a new frontier in skincare: formulas that work - not just with what your skin needs - but when it needs them most.
From Raaie to Raeso: A Name With Purpose
In this new era, Raeso blends two ideas: Ra (sun) and esō (within).
Together they capture the brand’s core philosophy: skincare that moves in sync with the body’s internal rhythm for improved efficacy. It’s a simple idea with profound implications for how we think about our morning and evening routines.
Whether you’re a longtime Raaie devotee, discovering it when we launched it in the UK in 2025, or are discovering this brand for the first time, Raeso marks something genuinely exciting in the skincare conversation: a shift from what we put on our skin to when we put it there - and why that timing can really work to transform your skin.

What Is Circadian Skincare - And Why Does It Matter?
Circadian skincare is the practice of applying the right ingredients at the right time of day, working with your skin’s natural 24-hour biological cycle rather than against it. This is not just a wellness trend - it’s backed by the emerging science of chronobiology.
Chronobiology - the study of the body’s innate 24-hour biological rhythms - shows that more than 1,400 genes follow circadian patterns governing barrier strength, antioxidant activity, DNA repair, inflammation, and cellular turnover. In other words: your skin has a biological schedule, and most skincare routines completely ignore it.
Raeso answers this with time-responsive formulas - combining encapsulated actives, slow-release delivery systems, and bio-adaptive botanicals engineered to perform well beyond the moment of application.
The Science: Your Skin Has a 24-Hour Schedule
Raeso’s scientific work (more about that later) maps how ingredient absorption, barrier integrity, lipid levels, and repair genes fluctuate hour by hour. Here’s what the research reveals:
Morning: Shield + Support (6am–8pm)
In the morning, skin is at its strongest - barrier function peaks, absorption is lower, and TEWL (trans-epidermal water loss) is minimal. This is your window for protective and preventative actives:
- SPF: your non-negotiable.
- Antioxidants (Vitamin C): defend against UV and pollution.
- Niacinamide: strengthen barrier, calm redness, regulate oil.
- Hydrators and humectants: lock in surface moisture.
Key Raeso products for morning:
→ Raeso Tranquility Water Activating Mist
→ Raeso Morning Dew Vitamin C Serum
Evening Power Hour: Peak Permeability (approx. 8pm–10pm)
As the evening progresses, skin becomes significantly more permeable and biologically active. Enzymatic repair pathways switch on, antioxidants deplete, and the skin opens to receive active ingredients with higher efficiency. This is your prime window for deeper-acting formulas:
- Retinoids: boost cell turnover, smooth texture, fade pigment.
- Peptides: support structure and repair.
- DNA repair enzymes: help undo the day’s UV damage.
- Ceramides and lipids: rebuild the barrier overnight.
Key Raeso products for evening:
→ Raeso Yellow Moonbeam Retinal Elixir
Night: Repair + Renew (10pm–2am)
Permeability peaks, priming skin for detoxification and maximum active ingredient absorption. DNA repair and cell turnover surge. This is when the most sophisticated overnight treatments earn their keep.
Backed By Research
To deepen its scientific foundation, Raeso partnered with Dr. Dan Yarosh - a molecular biologist and globally recognised authority on skin DNA repair and advanced delivery systems, formerly Chief Technology Advisor at La Mer and Estée Lauder.
Together, they co-authored a peer-reviewed paper in the International Journal of Cosmetic Science, confirming that while consumer knowledge of circadian skin rhythms is limited, there is strong willingness to follow time-of-day skincare guidance - affirming Raeso’s circadian-aligned approach.
The brand has also published a white paper - “Biohacking the Skin’s Biorhythm” - outlining how barrier strength, permeability, DNA repair, and metabolic activity shift across the 24-hour cycle. Rigorous science, made usable.
Raeso’s formulas are still powered by New Zealand’s uniquely resilient botanicals - plants that have evolved under some of the world’s most intense UV conditions, developing extraordinary antioxidant and adaptive responses. These bio-adaptive botanicals are engineered to perform not just at the moment of application, but across the hours that follow, releasing actives in sync with the skin’s own biological schedule.
Skincare That Works Harder, Not Louder
Raeso is for those who want more from their skincare without more complexity. The brand reframes the question we ask of our routines - from “when do I apply this?” to “when is my skin most receptive?”
