Oxford Psychologist Reveals: 86% of People Prefer This Skin Tone Over Paleness – And It's Not a Tan
Identical faces. Just a subtle shift in skin tone: 86% of women chose this man as more attractive. But where does the tone actually come from?
Last updated: January 8, 2026
Words by Larry L
If you don't have an open mind, please stop reading here. Because you are going to learn about a completely new scientific discovery about skin tone.
(It's actually a billion-year-old natural process)
It’s clinically proven that humans are hardwired to find certain skin tones more attractive, often without exactly knowing why.
When asked about the preference, people have vague ideas, like “they look healthy"
But the real underlying mechanism has been hidden until recently.
That mechanism will be explained in this article.
Attraction is based on deep-rooted biology.
Most attraction signals are actually not obvious, just biologically hard-wired.
Things like red lipstick on women or a sharp jawline on men are things that can seem random at first, but are widely rated attractive by the opposite sex.
And humans are extremely fast at evaluating faces.
People report taking an average of 1-3 seconds before swiping on Tinder:
That’s not long enough to make a full, conscious evaluation.
It’s automatic, subconscious.
you just know.
In real life, our brains make judgements even faster than on dating apps:
Research shows that the first impression is made in the first 100 to 200 milliseconds
We are constantly reading faces without even knowing it.
Attraction signals are fine-tuned. But for those who know the underlying science and delicate mechanisms behind attraction…
…There are ways to cheat the system
Hidden Mechanism Behind Skin Tone – The Study That Changed Everything
To understand the real underlying mechanisms behind skin tone, we need to look past just the commonly known mechanism:
Melanin, tanning from UV-radiation.
Instead, we need to look into the most recent research around skin tone and attraction.
Studies from world's leading neuroscientists and Oxford-trained perception psychologists
...findings on skin tone that have been replicated in various studies, published in journals all over the world.
Why exactly do people feel confident with a vibrant, glowing skin?
It makes your eyes look brighter, jawline sharper, bone structure more defined. Evens out skin tone, hiding blemishes and imperfections.
But it’s more than just darkening the skin.
It's about signaling good health and vitality.
But it can be overdone, attraction is a balancing act.
The greatest advantages for attractiveness are strong enough for the subconscious mind, but subtle enough to not be obvious:
Unnatural spray tan is widely seen as unattractive.
It screams:
“I’m chemically enhancing my skin tone, I’m trying too hard”
But subtly vibrant skin is irresistible, leaving people thinking
“There’s something about them, but I don’t exactly know what”
So, what exactly is the most attractive way to signal these qualities?
This is exactly what researchers Lefevre and Perrett looked into in a study titled
Fruit over sunbed (2015)
Published in The Quarterly Journal of Experimental Psychology.
With face-pair comparisons, the study looked into the real root cause behind skin tone and attractiveness in men and women, cross-culturally.
First, let’s meet the authors:
Carmen Lefevre PhD, Neuroscience expert from the Centre of Decision Research at Leeds University
and
David Perrett PhD from Oxford University, Head of the Perception Lab at University of St. Andrews.
When comparing otherwise identical face pairs, Lefevre and Perrett found that 79% of people prefer darker, melanin-rich versions over pale faces.
Same features. Same lighting. Same bone structure and facial expressions. Just a subtle shift in skin tone.
No surprise here, people love to look tanned
…But the second finding completely changed how experts see skin tone today:
In the second part of the study, they adjusted the warmth of the skin tone, instead of the darkness.
86% of people preferred the warm coloration over pale faces!
Almost 9 times out of 10!
So, the warmth was preferred over paleness
but more surprisingly, warmth was preferred more than darkness!
Why?
Because there is more to skin tone than we have been told.
There is more than just darkness, more than sunlight, more than UV and melanin.
This is what the third – most groundbreaking phase of the study – was designed to find
The most effective biolgical mechanism behind attraction and skin tone:
So Lefevre and Perrett compared darkness to warmth.
…warm faces were chosen as more attractive 75% of the time!
3 out of 4 people preferred warmth over darkness.
For decades, people focused on getting darker, stimulating melanin.
Yet, these results suggest that people have been focusing on the wrong system entirely.
But where does this warmth come from?
The warmth of our skin tone is caused by nutrients called carotenoids. They are natural pigments from colorful foods.
Carotenoids are not a new thing, not a chemical solution, not a new finding of the skincare industry.
Instead, they are pigments that have existed for over a billion years in nature…
When eaten in large amounts, they accumulate in the outer skin layers.
We actually already eat carotenoids every day, Most modern diets just don't include enough of them to see the effects on our skin.
There are examples of carotenoid-coloration everywhere around us:
What makes flamingos pink or salmon orange?
It's not their genetics.
Baby flamingos are actually born grey. The pink color comes from their diet – shrimp and krill rich in carotenoids.
Wild salmon gets its color from krill, but farm-raised salmon is actually greyish until it’s fed carotenoid supplements – to make it easier to sell!
What about the color in carrots, tomatoes and sweet potatoes? The color comes from carotenoids as well.
And if you are able to understand these natural mechanisms, the findings of Lefevre and Perrett make perfect sense:
Humans have not one, but two separate pigment systems.
And they both show people’s health choices on their skin:
Melanin, color from the outside
From UV-Exposure. Sign of skin damage.
Skin produces melanin, trying to defend itself from more damage.Carotenoids, color from the inside
Carotenoids come from various colorful foods: fruits, vegetables, seafoods in our diet.
When eaten consistently, carotenoids accumulate in the skin and create a subtle warm coloration.
When you understand how these mechanisms work, it becomes obvious:
Of course humans find carotenoids more attractive, they signal dietary choices, not UV-damage like melanin.
David Perrett has actually researched this difference further.
Perrett suggests that the attractiveness of melanin might just be because it imitates carotenoids, not the other way around!
Read that again:
The Oxford-trained professor is saying that tanning might only look good because it accidentally imitates what carotenoids do.
Why Haven’t I Heard About This Before?
Even though carotenoids are not yet widely known, this is not just some hidden theory or some sort of sacred knowledge.
Instead, it’s a classic story of scientific breakthroughs being ahead of the market. Even though all of the information is visible online, and the studies are publicly available, not many people have caught up yet.
Just like the essential Omega-3 , were discovered by researchers in the late 1920s, but they were only popularized in the early 2000s!
Through reading this article, you are just ahead of the mass of the market on carotenoids.
Can you Just Eat More Carrots?
So carotenoids come from foods. Can I just get them by adjusting my diet?
Yes and No
There are people who get enough carotenoids from their diet to see a change in their skin tone.
But unfortunately, they are extreme outliers.
There are two difficult requirements for the skin-tone effects of carotenoids, which is why almost all of the success stories are from people using supplementation.
Requirement #1 Dosing
For most people, there’s a volume problem. Visible carotenoid accumulation in skin through diet requires a high daily volume of very specific foods, like shrimp, salmon, and colorful vegetables.
With most people struggling to follow the normal dietary recommendations, going even further and adding 3 to 4 daily doses of specific colorful foods is just not a realistic long-term solution.
So, it’s theoretically possible, but it gets expensive quick, and it requires a lot of daily effort.
Just like getting enough Vitamin D from daily sunlight and certain foods is theoretically possible, but around 35% of Americans choose to use vitamin D supplements instead.
Our bodies respond to nutrient consistency, and supplements are a proven way to balance the intake with normal daily life.
Requirement #2 Balance
Recently carotenoids have started to become more commonly known, leading to social media trends with people eating large doses of carrots for skin coloration.
But beta-carotene – the pigment in carrots – alone shifts skin tone too far towards yellow. It often leads to a harmless, but odd-looking condition called carotenemia.
That’s definitely not a signal we desire.
Because carotenoids are a group of nutrients – just like vitamins are – eating a massive dose of one carotenoid is not a great skin tone solution. Just like eating a massive dose of one vitamin is not a great health solution.
The best skin-tone results come from eating a combination of different shades of carotenoids consistently.
This is very intuitive when you understand the biology behind carotenoids : the attractiveness of carotenoids comes from imitating the skin tone from a varied diet, not from imitating a massive dose of one food.

Just in a condensed, easy to use capsule.
Astaxanthin for deep undertone
Lycopene for bright vibrance
Beta-carotene for the amber-colored warmth.
Zephyrian goes the extra mile, only using naturally sourced carotenoids, instead of the cheaper, synthetic versions.
No filler chemicals.
Nothing unnecessary
GMP manufacturing.
FDA approved facility.
3rd-Party Laboratory testing for potency and safety.
Formulated for results that people notice, but are not quite sure about:
Formulated for results like Norberts:
Norbert’s story – What Carotenoids Look Like in the Real World
Norbert is a 28-year old sports therapist from Vienna, Austria.
Not a beauty professional or a biohacker,
but someone who used to struggle with paleness
Working in health like Norbert does, his face is a walking self-advertisement.
Looking good is not just added confidence, it’s a professional advantage.
Around 9 months ago, after returning from a trip to Latin America, he wanted to maintain some of the natural color he had gotten.
Instead of going back to the baseline, Norbert wanted to keep the confidence he had during his travels.
So he found Zephyrian and decided to give it a try:
After three months of taking one capsule a day, here’s what he had to say:
Finally not as white as the wall
I started taking Zephyrian in the middle of European winter, after coming back from a trip to Latin America.
My goal was to prolong my colour for a while, because usually if I achieve a "tan“ aka slightly beige skin.
After max 2 weeks I‘m back to normal, which is a level of white , where people start to ask me if I‘m alright
😅 After 3 months 1 capsule a day, I can say, I finally have a natural glowy colour, that looks totally natural for my skin type.
No supplement, that I ever tried before achieved this level of results. You have a new fan Zephyrian! All in all definitely a 5 stars recommendation.
Timeline - How long until I see results with Zephyrian?
Carotenoid buildup depends on personal factors, like your baseline coloration, consistency of supplementation and dietary fats (carotenoids are fat-soluble!)
Some start to see the difference in 2 weeks, others take 4-6 weeks. However, most people see full results by 9–12 weeks of daily supplementation.
This is not painting the surface or an overnight solution. Instead it’s a build-up from within.
But once it kicks in, it’s hard to go back.
Donovan saw a golden shift after 2 weeks.
"I have to say was kinda skeptical at first, but after just 2 weeks I started to notice a richer golden tone on my skin."
Peter-Christian noticed nothing for 2 months, then darkened fast.
"2 months not see nothing different but now something changed and skin is darker."
Diego tanned gradually:
I started seeing improvements after 2-3 weeks, but once I upped to 2 pills per day for a further 5-6 weeks my tone has changed even more noticeably - people keep asking me how I look so tanned! :)

FAQs
Is this a self-tanner?
No. There’s no immediate effect, it’s not painting the skin.
If you are looking for overnight results, Zephyrian is not a great fit for you.
Carotenoids work through accumulating in the skin over a period of a few weeks.
Will I look Orange or Yellow?
No. That effect is associated with isolated plain beta-carotene. Zephyrian uses different carotenoids, a balanced, triple-carotenoid formula to create natural warmth.
The reason other products use plain beta-carotene is simple: the price.
It’s around 7x cheaper than Lycopene, and around 25x cheaper than Astaxanthin.
Beta-carotene is the most commonly known skin-changing carotenoid. Low doses of beta-carotene are helpful, but high doses can cause the skin to turn unnaturally yellow. For this reason, it's not advised to rely on it alone, even though it would be cheaper.
Instead, we developed a diverse carotenoid formula that mimics a real dietary mix. Zephyrian results come from darker, more attractive carotenoids, with a small, supporting dose of natural beta-carotene.
Does it actually work?
Yes. And we stand by it.
If you don't see visible skin tone improvement after 90 days of daily use, you get every penny back. Even if all your bottles are empty.
Here's why we can make this promise:
We've seen it work on ourselves
We've seen it work for 8,000+ customers with every skin type
The science behind carotenoids is bulletproof – backed by universities worldwide
The guarantee applies to:
All 3-bottle bundles (33% off + free shipping)
All 5-bottle bundles (40% off + free shipping)
Why only multi-packs?
Because carotenoids build up gradually in your skin tissue over 8-12 weeks. Single bottles can run out before you see the full transformation. We're protecting you from quitting too early, not protecting ourselves from refunds.
How long does it take to see the results?
The exact timeline depends on individual factors, like diet, baseline skin tone, and consistency.
Most people notice first changes within 2-6 weeks of consistent usage, and full transformation at around 9–12 weeks.
Donovan saw a golden shift after 2 weeks.
"I have to say was kinda skeptical at first, but after just 2 weeks I started to notice a richer golden tone on my skin."
Peter-Christian noticed nothing for 2 months — then darkened fast.
"2 months not see nothing different but now something changed and skin is darker."
Diego tanned gradually:
I started seeing improvements after 2-3 weeks, but once I upped to 2 pills per day for a further 5-6 weeks my tone has changed even more noticeably - people keep asking me how I look so tanned! :)
This is a build, not a spray. But once it kicks in, it’s hard to go back.
Is it safe to take long term and is it approved by authorities?
Yes, and yes.
You’ve most likely eaten these nutrients before, just not at these levels.
Everything inside Zephyrian comes from nature. Astaxanthin from algae. Lycopene and Beta-carotene from fungi. The exact same pigments that make tomatoes red, carrots orang and shrimp and salmon pink.
They’re backed by clinical studies and used widely in supplements for skin, vision, and health.
The ingredients are naturally occurring dietary carotenoids commonly found in food. Zephyrian is third-party tested for safety and purity.
If you smoke, are on medication or have any prior health conditions, consult a doctor before usage.
Authorization facts
Lycopene (E160d) is an authorised food colour in the EU and is approved by the UK Food Standards Agency for use in food supplements up to 15 mg per day.
Astaxanthin from Haematococcus pluvialis is recognised as a novel food in the EU and is approved by the UK Food Standards Agency for food-supplement use at up to 8 mg astaxanthin per day.
Beta-carotene (E160a(ii)) is an approved food colour and vitamin A source in the EU and is listed on the Great Britain Register as a permitted ingredient for food supplements under UK regulations.
Why do most people buy the 3- or 5-bottle option?
Because tone takes time, and those options save you money.
It takes weeks to build up enough pigment to see real change. That’s why most customers commit to 3 bottles (33% off) or 5 bottles (40% off).
They also unlock the guarantee and ship free.
More results. Less risk. Fewer excuses.
Do I have to pay for shipping?
Not if you’re serious.
Shipping is free on 3- and 5-bottle orders.
It’s our way of rewarding commitment, and making sure you’ve got enough to see the full effect.
Will this affect my freckles or dark spots?
Not directly. But here’s what it will do:
Freckles and spots aren’t erased (this isn’t a concealer). But once your overall tone warms and evens out, imperfections often feel less obvious.
Is there any real science behind this?
Yes, just see all of the studies below!
Your body already knows these ingredients.
Carotenoids like astaxanthin and lycopene are widely known and have been clinically studied for their effects for skin hydration, elasticity, and pigmentation.
They’re what give flamingos, salmon, and tomatoes their color.
We just borrowed nature’s palette and gave it a purpose.
