Built on Circadian Skin Science™, RAESO is founded on a simple yet overlooked truth: skin is not static, it operates on a 24-hour rhyhtm - defending by day, repairing by night. When skincare works in sync with this cycle, results accelerate, resilience strengthens, and skin performs at its highest potential.

RAESO blends Ra (sun) and esō (within), capturing the brand’s core philosophy: skincare that works in harmony with the body’s internal rhythm for improved efficacy.

The name is deeply rooted in dual meaning. Ra refers to the ancient Egyptian solar deity, while Rā also means “sun” in te reo Māori, grounding the brand in both global mythology and our New Zealand origins.

RAESO was inspired by the complex relationship we have with the sun.

The sun is a life-giving force. It supports our mood, strengthens our immune system, benefits gut health, and regulates melatonin,o ur sleep cycle, which in turn plays a critical role in skin repair and regeneration.

Yet, this same force is also the leading cause of premature skin ageing. In fact, up to 80% of visible ageing is attributed to sun exposure.

In New Zealand, this impact is even more pronounced due to our uniquely harsh UV environment, intensified by the thinning ozone layer. Research highlighted by Australian dermatologist Dr Greg Goodman shows that women in the Southern Hemisphere can experience signs of ageing, such as wrinkles and sagging, up to 20 years earlier than those in the Northern Hemisphere.

Sun damage accelerates visible ageing, contributing to wrinkles, rough and dull skin, pigmentation, broken capillaries, and loss of firmness.

RAESO exists to navigate this contradiction, harnessing the benefits of the sun while protecting against its damage, through formulations that work with the skin’s natural biological rhythms.

RAESO is built on a fundamentally different approach to skincare - one that works with your skin, not against it.

Our formulations are designed to align with the skin’s natural Circadian rhythm, supporting protection during the day and repair at night. This allows active ingredients to be delivered when the skin is most receptive, improving results while reducing the risk of irritation.

Rather than chasing trends, RAESO focuses on biological timing, ingredient synergy, and long-term skin health.

Your skin behaves very differently across a 24-hour cycle.

During the day, it is in defence mode, protecting against UV exposure, pollution, and oxidative stress. At night, it shifts into repair mode, focusing on regeneration and renewal.

Using the right ingredients at the right time allows you to support these natural processes, maximising efficacy without overloading the skin.

RAESO was founded on the understanding that the sun is both essential, and damaging.

Sunlight supports mood, immunity, and sleep regulation, all of which impact skin health. But it is also responsible for up to 80% of visible ageing.

Our approach is not to avoid the sun entirely, but to help your skin better manage its effects, through daily protection, targeted repair, and formulations that strengthen the skin over time.

UV radiation causes skin to age in several ways. It causes stem cells to die off, leading to thinning and wrinkling of the skin. It also activates enzymes called matrix metalloproteinases (or MMPs for short) which break down collagen.

Yes. No. It depends... The honest (and boring) answer is that it doesn’t exactly help your skin (dehydration, puffiness, dark circles, etc etc.)

Protect in the morning and repair at night.

Protect using Morning Dew Vitamin C Serum and Sun Milk Drops SPF50 sunscreen.

Repair using Yellow Moonbeam Retinal Elixir and Lunar Veil Chrono-Active Sleep Mask to reverse sun damage, reduce wrinkles, smooth out skin tone and boost radiance.

You may notice immediate improvements in hydration and radiance.

Within 2-4 weeks, skin typically appears smoother and more even. More significant changes, such as improvements in pigmentation, fine lines, and firmness, develop over 8-12 weeks with consistent use.

They’re all from the same retinoid family, but retinal (AKA: retinaldehyde) has been clinically proven to work up to 11 times faster than retinol. Retinal also has a much higher exfoliation rate than retinol, which contributes unclogging pores, making skin smooth, soft, even-toned, freaking RAD-I-ANT. 

It truly is a wonder ingredient, and the reason it is used less than retinol is:
a) It’s more expensive
b) In the past, it’s been hard to stabilize (meaning it loses its potency as it sits in the bottle on your windowsill). However, our Retinal is encapsulated (using amazing patent-pending technology) and releases slowly and gently into your skin overnight.

Retinoids are proven to be safe is you start slowly. Our collagen stores start to rapidly break down from 30 onwards, so this is a good time to incorporate retinols that encourage cellular turnover to keep the skin firm. Undoing the damage to your skin in later decades is that much harder.

The Morning Dew Vitamin C Serum is great for pregnant and breastfeeding women, as it helps to prevent hyperpigmentation which is common during pregnancy due to endocrinological changes.

The Sun Milk Drops SPF50 is great for pregnant and breastfeeding women because it is a mineral (physical) sunscreen, delivers broad-spectrum protection, and is fragrance free.

We do not recommend the Yellow Moonbeam Retinal Elixir for pregnant women as it contains vitamin A. This is in line with the advice from the American Academy of Dermatology, which advises that against using vitamin A-based products throughout pregnancy.

We would encourage breastfeeding women to speak to their dermatologist/ GP/ obstetrician if they are really keen to give it a try because most experts will tell you retinaldehyde (retinal) is safe when breastfeeding because a the amount that could enter the bloodstream is negligible. According to the major dermatology journals looking at safety of ingredients, tretinoin (a way more potent version of Vitamin A than retinal) is deemed “moderately safe” and “unlikely absorbed in significant quantities.” Retinoid use while breastfeeding is always a personal decision, as there have not been any studies done looking specifically at topical retinoid/retinol use during lactation.

Yes. RAESO is designed with skin balance in mind.

By aligning ingredients with the skin’s natural rhythm, we reduce the likelihood of overstimulation. Our formulations also prioritise barrier support, ensuring the skin remains resilient, hydrated, and less reactive over time.

Our Morning Dew Vitamin C Serum in is gentle (even at 15% concentration) so you can use it every day even if you are not a Vitamin C pro. 

Our Yellow Moonbeam Retinal Elixir is a stronger ingredient so we recommend using it every third day for a couple of weeks, and increasing to every second night, and then every night based on your skins tolerance level.

Most mainstream skincare products you see on the shelves are cosmetic.

Meaning: they might feel nice on the outer layers of the skin because they are made up of non-active ingredients like glycerin that feels hydrating but are just sitting on the top layer of your skin and not doing much to change the skin at a deep, cellular level where real changes happen.

The term cosmeceuticals was formed from a combination of ‘cosmetics’ and ‘pharmaceuticals’. Cosmeceutical products stand out because the active ingredients change the skin on a cellular level and improve the functionality of cells i.e. giving consumers what they really want from skincare; results. The results you get from cosmeceuticals are generally faster, more noticeable and longer lasting. However, there is believed to be a trade-off between efficacy and safe ingredients: Many believe this pharmaceutical approach contains toxic and unsafe ingredients that will irritate skin or disrupt the body’s natural ecosystem by way of things like hormone disruptors.

Enter: Clean Cosmeceuticals. We searched the globe for the most effective, peer-reviewed skincare ingredients, and then found the cleanest, most ethical sources of these. All our ingredients are classified by the Environmental Working Group (EWG) which is a non-profit, nonpartisan organization dedicated to “shining a spotlight on outdated legislation, harmful agricultural practices and industry loopholes that pose a risk to our health and the health of our environment”.  

No, we never test on animals.

We recommend storing your products in a consistently cool, dry place, away from direct sunlight.

We do everything we can to source materials that are both safe for the planet and safe for the person. We also ensure our ingredients are sustainably produced, have a low impact on the land, and are easily regenerated. For example, in marine algae harvesting, our suppliers follow Tikanga Māori - a strict, traditional harvesting practice of the indigenous people of New Zealand. By using this time proven approach, we harvest our ingredients without compromising our environmental and social responsibilities. This respectful approach means we can offer high potency natural bioactives whilst respecting the land and water that the ingredients came from.
