Sunburn treatment in Railay
The sun here is stronger than almost anywhere most visitors come from, and it does not feel like it — a sea breeze on a limestone beach masks the burn until the evening. Sunburn treatment in Railay covers everything from a painful red back to blistering burns that need dressing properly, and the distinction between the two matters more than people think.
Why Railay burns people so efficiently
Krabi sits at about eight degrees north, so the sun is close to overhead and the ultraviolet index regularly reaches eleven or twelve. That is the top of the scale, where unprotected skin burns in around ten to fifteen minutes.
Then the local multipliers. Water reflects light back up at you, so you burn from below as well as above. Pale limestone does the same at the crag. A breeze off the sea removes the heat sensation that would otherwise tell you to move.
And the specific Railay trap: a long boat ride, where you are stationary, exposed, and cooled by wind and spray for the entire crossing.
First degree or second degree
First degree is red, hot and sore, with no blisters. The skin stays intact and it peels after a few days. Unpleasant, not dangerous.
Second degree involves blisters, and that is a different situation — the skin barrier is broken, fluid is being lost, and it can become infected. Extensive blistering, particularly across the back or shoulders, deserves proper assessment and dressing rather than aloe vera from a beach shop.
Come in for blistering over a large area, for any burn with fever or chills, for confusion or dizziness, for a burn on a child, or for a burn that becomes increasingly painful and red after day two rather than settling.
What actually helps in the first 24 hours
Get out of the sun completely, not into partial shade. Cool the skin with cool showers or damp towels, repeatedly, rather than one long cold session.
Drink considerably more than usual. A large burn pulls fluid into the skin and away from circulation, and dehydration on top of sunburn is how people end up needing an IV drip.
Ibuprofen genuinely helps here, because much of the pain is inflammation — unless there is any question of dengue, in which case paracetamol only. Aloe vera gel, kept in a fridge, is soothing and harmless. Plain moisturiser once the heat has gone helps the peeling stage.
What not to put on it
No butter, oil, coconut oil or toothpaste. They trap heat, and coconut oil in particular gets recommended constantly here and does nothing useful for a fresh burn.
No ice directly on the skin, which adds a cold injury to a heat one. No anaesthetic sprays containing benzocaine on broken skin, which sensitise it. And do not pop blisters — that roof of skin is a sterile dressing, and removing it invites infection.
If a blister bursts on its own, clean it gently and cover it. That is a wound now, and it wants proper dressing rather than being left open on a beach.
Sun poisoning, which is a real thing
A severe burn over a large area can produce systemic effects: fever, chills, nausea, headache, dizziness and profound tiredness. People describe it as feeling like flu the day after a beach day.
That is a burn large enough to cause an inflammatory response and significant fluid loss, and it is usually accompanied by heat exhaustion because the same day produced both.
It responds well to fluids, rest and anti-inflammatories, and to being assessed rather than endured. Confusion, vomiting that will not stop, or fainting move it into the urgent category — see urgent medical care.
Climbing and diving with burnt skin
A harness over burnt hips is genuinely unpleasant, and a rope running across a burnt forearm on a lower is worse. Most people take a day or two off, and that is the sensible answer.
Burnt skin under a wetsuit is another matter. The friction of pulling neoprene over a blistered shoulder tears the blister roof off, and salt water in the raw skin afterwards is a real infection risk on this coast.
A rash vest is the practical solution for the rest of the trip. It protects the burn, prevents the next one, and does not need reapplying every two hours.
Not burning again for the rest of the trip
High factor sunscreen, applied more generously than feels reasonable, and reapplied every two hours and after every swim regardless of what the bottle claims about water resistance.
Cover up instead where you can. A rash vest, a hat and a shirt outperform any sunscreen, and they do not wear off. Stay out of direct sun between eleven and three, which is also when the viewpoint trail does most of its damage.
And protect the burn you already have. Newly healed skin pigments unevenly and burns again easily for weeks, and a peeling back exposed to another full day of Thai sun is how a bad holiday becomes a memorable one.
Frequently asked questions
How long does sunburn take to heal?
A first-degree burn settles in three to five days and then peels. Blistering burns take one to two weeks and need keeping clean.
Should I pop the blisters?
No. The blister roof is a sterile dressing. If one bursts on its own, clean it and cover it.
Is coconut oil good for sunburn?
No, despite how often it is suggested here. It traps heat in a fresh burn. Cool water and aloe vera gel are better.
When do I need to see someone?
Extensive blistering, fever or chills, confusion or dizziness, a burn on a child, or a burn getting more painful after day two.
Can I swim with sunburn?
Salt water on intact burnt skin stings but is not harmful. On broken or blistered skin, stay out — infection risk on this coast is real.
Why did I burn on the boat?
Wind and spray remove the heat sensation that normally warns you, while reflected light off the water doubles the exposure. Boat rides burn more people here than beaches do, and the crossing from Ao Nang is long enough to do real damage before you have even arrived.
Can I climb with a burnt back?
You can, but a harness and rope across burnt skin is miserable. Most people take a day or two and wear a rash vest afterwards.
Who treats you here, and who is behind them
The clinic on Railay is run by experienced English-speaking nurses. Behind them sits Doctor Ao Nang Takecare Medical Clinic in Ao Nang, which Takecare Clinic Railay works together with as one service rather than two businesses: shared doctors, shared records, shared treatment plans. In practice that means a doctor is pulled in the moment your case needs one — to review it, to prescribe, or to come across to the peninsula in person. If you later cross to the mainland, whoever sees you is already holding your notes and you are not starting the story again. It also means the second opinion that would otherwise cost you a boat and half a day costs a phone call.
Getting seen
Opening hours are 8am–10pm daily. Outside them we are still reachable 24 hours by phone, WhatsApp and Line, so when something happens at eleven at night the right move is to message us, not to lie awake deciding whether it can wait. No appointment is needed at any point — walk in, or reach us on +66 81 718 9080, WhatsApp or Line. If you would rather not move, ask for a doctor resort visit and we will come to you. And if this turns out to be something the peninsula cannot handle, that call is also how the boat and the hospital transfer start moving.
