Chlorine strips skin oils, accelerates exfoliation, and degrades sunscreen — all of which change how your tan develops and fades. Here's what the science says about pool chemistry and your skin.
Facial skin is thinner, has more melanocytes, and ages faster under UV. Here's the science behind why your face needs its own tanning and sun-protection routine.
Melasma causes dark patches on the face that worsen with UV and visible light. Here's the science behind what triggers it, who's most at risk, and how to protect your skin.

Freckles and tans are both responses to UV radiation, but they work in completely different ways. Here's the science behind why some people freckle while others tan — and what it means for sun safety.
The MC1R gene controls which type of melanin your skin produces. In redheads, it favours pheomelanin — a pigment that offers almost no UV protection and may actively damage skin cells.
Sunscreen does expire — and heat, light, and time can degrade its active filters long before the printed date. Here is how to tell if your SPF still protects you.
Most people apply only 25–50% of the sunscreen they need — slashing their real SPF by more than half. The two-finger rule is the simplest way to fix that.
UPF-rated clothing blocks both UVA and UVB radiation more reliably than sunscreen. Here is what the science says about how it works, what affects the rating, and when to choose fabric over SPF.
UV radiation can cause serious eye damage during tanning — from photokeratitis to cataracts and eyelid cancer. Here is what the science says about protecting your eyes in the sun.

UV exposure during pregnancy raises specific risks including melasma, folate degradation and overheating. Here is what the research says about sun safety for expectant mothers.
Air pollution can block up to 50% of UV radiation — but it also damages skin in ways that amplify sun exposure. Here's the science behind pollution, UV and tanning.
Sun exposure may temporarily mask blemishes, but UV radiation can worsen acne by boosting sebum, blocking pores and darkening scars. Here is what the science actually says.
Melanocyte density drops 8–20% per decade after 30, thinning your tan response and raising UV risk. Here is how ageing changes your skin type — and how to adjust your tanning approach safely.
Tanning beds emit up to 15 times more UVA than the midday sun and are classified as Group 1 carcinogens. Here's how indoor tanning compares to natural sunlight — the UV spectrum, skin cancer risk, and what the evidence actually says.

Winter UV levels drop but never disappear. Here's when cold-weather tanning is realistic, how snow and altitude change the equation, and what the science says about UV exposure in the colder months.
How long you can safely tan depends entirely on your Fitzpatrick skin type. Here are the exact burn times, safe exposure windows, and SPF recommendations for every skin type from I to VI.

Lips have far fewer melanocytes than regular skin, making them almost unable to tan — but highly vulnerable to UV damage. Here's what science says about lip sun protection.
Standard glass blocks nearly all UVB but lets up to 75% of UVA through. Here's what that means for tanning, skin damage, and vitamin D — backed by dermatology research.

Water-resistant doesn't mean waterproof. Here's how sunscreen water resistance is tested, what the 40- and 80-minute ratings mean, and when you actually need to reapply.
The answer lies in the MC1R gene, pheomelanin, and a DNA repair system that works differently in fair skin. Here's the science behind why some people always burn.
From the moment UV hits your skin to the next morning, your body launches a complex chain of DNA repair, inflammation, and melanin production. Here's the hour-by-hour timeline.
Your minimal erythemal dose is the UV threshold where tanning ends and burning begins. Learn what MED means, how it varies by skin type, and how to use it to calculate safe sun exposure time.
Erythema is the medical term for skin redness after UV exposure. Learn what triggers it, how the inflammatory cascade works, and why that first flush of pink is a warning sign you shouldn't ignore.
People use 'sunblock' and 'sunscreen' interchangeably, but they originally meant different things. Here's what the science says — and which type is better for tanning.
Many people layer tanning oil over sunscreen hoping for the best of both worlds. Here's what the science says about whether combining them actually works — and how to do it without wrecking your SPF.
Tanning oil with SPF 30 sounds like the best of both worlds — a golden glow with real protection. Here's what dermatologists and the science actually say about whether it delivers.
Athletes spend hours in the sun, but UV exposure affects more than just skin colour. Learn how sunlight influences vitamin D, nitric oxide, muscle recovery, and what outdoor athletes need to know.
Sensitive skin needs careful sun protection. Learn the science behind mineral vs. chemical sunscreen, which ingredients to avoid, and how to tan safely without irritation.

Tanning accelerators promise faster, deeper colour — but the science behind key ingredients like tyrosine and psoralen tells a more complicated story. Here's what actually works.
Sunscreen can't block all UV rays. Here's exactly how much gets through at every SPF level, why you still tan, and what broad-spectrum protection actually means.

Not all after-sun products are backed by science. Here are the ingredients with real clinical evidence — and the ones that are mostly marketing.
Sand reflects more UV than water, salt water increases sun sensitivity, and chlorine strips your skin's defences. Here is the science behind pool and beach tanning — and which setting actually works better.
The sun hits your skin differently at 9 AM and 4 PM — and the difference matters more than most people realise. Here's what solar angle, UV ratios, and circadian biology say about when to tan.
Most holidaymakers burn in their first 48 hours. Follow this day-by-day tanning plan to build colour gradually and avoid ruining your trip with sunburn.
UV radiation increases by 10–12% for every 1,000 metres of elevation. Learn why altitude makes sunburn so much more likely and how to protect yourself on the mountain.
UV radiation doesn't just darken your skin — it breaks down collagen at the molecular level. Learn how photoaging works, how it differs from natural ageing, and how to tan while minimising long-term damage.
Oestrogen boosts melanin production while progesterone suppresses it — meaning your hormonal cycle directly affects how quickly and deeply you tan. Here is the science.
Dry skin sheds pigmented cells faster, causing your tan to fade unevenly. Learn the science of skin hydration, barrier function, and evidence-based ways to keep your colour longer.
UV radiation does not just come from above. Sand, water and snow reflect UV back at your skin, increasing your total dose by up to 80%. Here is how reflected UV works and how to protect yourself.
The UV index forecast tells you how strong the sun will be — but how is it calculated and can you actually trust it? Here is what the science says about UV forecast accuracy.
SPF, broad-spectrum, PA++++, UVA star ratings — sunscreen labels can be confusing. Learn what UVA and UVB rays actually do, why broad-spectrum matters, and how to read any sunscreen label.

Tanning oils promise a faster, deeper tan — but at what cost? Here's the science behind how tanning oils and sunscreen actually work, what they do to your skin, and which one you should reach for.
Got sunburnt? Learn how to treat sunburn effectively with evidence-based aftercare — from cooling the skin and managing pain to repairing your skin barrier and speeding up recovery.
Yes — clouds let through far more UV than most people realise. Learn how much UV penetrates each cloud type, why overcast days can actually increase your exposure, and how to tan safely when the sky is grey.
UV levels, sun angle, and your skin's readiness all shift dramatically between spring and summer. Learn how each season affects tanning — and how to adjust your approach.
A natural tan typically lasts 7–30 days depending on your skin type. Learn why tans fade, what controls their lifespan, and evidence-based ways to extend your colour.
