Sunburn treatment in Koh Samui
Our doctor-led walk-in clinic assesses and treats sunburn the same day, from tender pink shoulders to blistered backs. We are in Bang Rak, minutes from Samui Airport and the Big Buddha, conveniently covering Chaweng, Bang Rak and Bophut. No appointment is needed and most patients are seen within the hour.
Why a few hours in the Samui sun does real damage
Koh Samui sits close to the equator, where ultraviolet levels stay extreme almost year-round. The UV index here regularly climbs above 11 by late morning, so the skin can absorb a burning dose in as little as 15 to 20 minutes, even under thin cloud. Sea breeze, water reflection off the pool or boat, and a cold drink in hand all mask the heat you would normally feel building. Many of our patients are surprised because the redness only shows up hours later, once they are back at the villa. Burns are also easy to underestimate on a first beach day, before the skin has had any chance to adjust.
What a sunburn actually looks and feels like
Sunburn is a genuine radiation injury to the outer skin layers, not simply a colour change. A mild first-degree burn stays superficial and settles within days, while a deeper burn blisters and takes longer to repair. Watch for:
- Skin that is red or flushed, hot to touch, and tight or stinging
- Pain that peaks roughly 12 to 24 hours after exposure
- Swelling, especially across the face, tops of the feet and shoulders
- Small fluid-filled blisters on more severely burned areas
- Itching and peeling as the damaged skin sheds a few days later
- Headache, tiredness or a mild feverish feeling when a large area is burned
Because the sun and tropical heat often go together, some visitors arrive with sunburn plus signs of overheating. If you also feel dizzy, weak or nauseated, our team will check you for heat exhaustion at the same visit.
Steps that soothe skin before you reach us
Get out of the sun straight away and stay in shade or air conditioning. Cool the skin with a lukewarm shower or a damp towel, then apply a plain, fragrance-free moisturiser or an aloe-based gel while the skin is still slightly damp. Drink more water than usual, as burned skin loses fluid. A standard dose of ibuprofen or paracetamol helps with pain and swelling if you have no reason to avoid them. Leave blisters intact, wear loose cotton over the area, and skip further sun until everything has healed. Avoid petroleum-heavy ointments, ice directly on skin, and any product with lidocaine or benzocaine, which can irritate.
How our doctors manage a serious burn
When self-care is not enough, a doctor examines the burn to judge its depth and how much surface area is involved. Treatment may include prescription-strength anti-inflammatory medication, a short course of topical steroid cream to calm severe redness, and proper dressing of broken blisters to keep them clean. Where large areas are raw or you are dehydrated, we can rehydrate and settle you quickly with an IV drip. If a blister has burst and looks infected, we assess it for a developing skin infection and start antibiotics when needed. You leave with a clear plan and, if you want one, a written medical report.
When sunburn is an emergency and you should go to hospital
Most sunburn is safely handled in a clinic, but some situations need urgent hospital care. Go to an emergency department, or call us first for guidance, if you notice:
- Extensive blistering across a large part of the body
- Confusion, fainting, a temperature above 39C, or a fast pulse
- Severe swelling of the face with vision affected
- Persistent vomiting or an inability to keep fluids down
- A very young child or infant with widespread burning
- Signs of spreading infection such as pus, red streaks and fever after a few days

Frequently asked questions
Can I still get badly burned on a cloudy Samui day?
Yes. Cloud filters very little ultraviolet light, and the UV index in Koh Samui often stays extreme even when the sky looks overcast. Water and pale sand also reflect UV back onto your skin. Many of the worst burns we treat happen on hazy days when people assume the sun is weak and skip sunscreen or shade.
How soon after getting burned should I be seen?
If the burn is mild and skin is only pink, home care is usually enough. Come in the same day if large areas are involved, blisters are forming, the pain is severe, or you feel unwell in yourself. Early treatment reduces swelling and lowers the chance of the skin becoming infected as it heals.
Is it safe to keep swimming or sunbathing while it heals?
No. Burned skin is already injured and needs a full break from the sun to recover, usually a week or more for a bad burn. Salt water and chlorine sting broken skin, and any further exposure deepens the damage. Cover the area, stay in shade, and use a high-factor sunscreen once the skin is no longer raw.
My child got sunburned. Should I worry more than for an adult?
Children have thinner, more delicate skin and lose fluid faster, so burns affect them more strongly. A young child with widespread redness, blistering, drowsiness or a fever should be checked promptly. We see children at the clinic and can also visit your accommodation if travelling is too uncomfortable for them.
Will sunburn leave a permanent mark or scar?
A superficial burn typically heals without scarring, though the skin may look blotchy or darker for a while. Deeper burns that blister and become infected carry a small scarring risk, which is one reason we treat serious burns properly. Every burn also adds to lifetime UV damage, so protecting the area afterwards matters.
Do I need antibiotics for a burst blister?
Not automatically. A clean, intact blister usually needs only gentle dressing. Antibiotics are considered when a blister has burst and the area shows infection, such as increasing pain, pus, warmth, red streaks or fever. A doctor examines the site and prescribes only if there is a genuine sign of infection.
Can you help if I burned and also feel dehydrated or hungover?
Yes. A day of sun, alcohol and too little water leaves many visitors flat and dehydrated. Alongside treating the burn we can rehydrate you with fluids and, if you wish, an IV drip to help you feel human again faster. Just let us know all your symptoms so we treat the whole picture.
Can I get a medical report for my travel insurance?
Yes. Every visit comes with a full itemised receipt, and we can provide a written medical report describing your sunburn and treatment. We also bill most major travel insurers directly, so in many cases you pay little or nothing upfront. Bring your policy details and we will guide you through it.
