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.

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.

UV radiation breaks down tattoo pigments through photodegradation — some colours fade far faster than others. Learn how the sun affects your ink and how to tan safely without ruining your tattoos.
Certain foods can genuinely improve your skin's colour, protect against UV damage, and help your tan last longer. Here's what the science says about eating your way to a better glow.
Self-tanners and real tans both darken your skin — but the science behind them is completely different. Learn how DHA creates colour without UV, what melanin actually does, and which option is safer.
UV levels vary dramatically around the globe — from extreme 14+ in Australia to barely 2 in Scandinavia. Learn which countries have the strongest UV, why, and how to protect yourself when travelling.
Uneven tanning is more common than you think — and it's not random. Learn why different body parts tan at different rates and how to get a smooth, even colour every time.
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.
Melanin is the pigment that gives your skin its colour — and your tan. Learn how melanocytes produce it, why eumelanin and pheomelanin matter, and what really happens inside your skin when you tan.
Want a deeper tan in fewer sessions? The science of melanin production reveals how timing, skin prep, and diet can speed up your tan without increasing UV damage.
From base tans to coconut oil, these popular tanning beliefs sound reasonable but fall apart under scientific scrutiny. Here is what the research actually says.
Your body produces vitamin D when UVB radiation hits your skin — but how much sun exposure do you actually need? Here is what the science says, broken down by skin type, season, and latitude.
Tanning and burning are both caused by UV radiation, but they involve completely different biological processes. Here is what actually happens in your skin — and why the distinction matters for your health.
