Sunburn treatment in Koh Samui
The tropical sun here is stronger than it feels. When a beach day leaves your skin red, blistered and burning, our English-speaking doctors cool the pain, protect the skin and get you back to your holiday.
Why Samui sun catches visitors out
Sunburn is skin damage caused by ultraviolet radiation, and near the equator that radiation is intense. A sea breeze, cloud cover, or the cool water off Chaweng and Bang Rak all mask how much sun you are getting, so many travellers only realise once the skin turns red, hot and tight hours later. A first-degree burn brings redness, soreness and sensitive skin. A deeper, second-degree burn blisters, weeps and swells, and can come with headache, chills, nausea and fatigue when a large area is affected. Peak damage is usually visible around 12 to 24 hours after exposure, which is why last night’s snorkelling trip can feel far worse this morning.
Fair skin, children, and anyone on certain medications burn faster, and reflected glare off the sea and white sand adds to the dose. Understanding how deep the burn goes guides the right treatment and the healing time ahead.
Self-care that genuinely helps
For a mild burn you can often manage at home while it heals over a few days. Get out of the sun, cool the skin, and keep the area moisturised and protected.
- Cool it with a cool shower or a damp cloth, not ice, for short spells
- Soothe it with plain aloe vera gel; a little coconut oil once the heat has gone can help dry, peeling skin
- Hydrate by drinking plenty of water, as burnt skin pulls fluid from the body
- Leave blisters intact to protect the raw skin beneath and lower infection risk
- Cover up and stay out of direct sun until the skin has fully healed
How our doctors treat a bad burn
Come in for sunburn treatment when the burn covers a large area, blisters have formed, the skin is too painful to touch, or you feel unwell in yourself. Samui Medical Clinic is a walk-in clinic in Bang Rak, so there is no need to book. A doctor examines the affected skin, checks how deep the burn goes, and looks for dehydration or heat illness. Treatment may include cooling and soothing measures, doctor-selected pain relief and anti-inflammatory medication, careful cleaning and dressing of blistered skin to reduce infection risk, and intravenous fluids on site if you are dehydrated from sun and heat. Our on-site pharmacy sends you home with everything you need, our on-site laboratory is on hand if tests are wise, and our doctors make hotel and villa visits island-wide if you are too sore to travel.
Red flags: when to seek urgent care
Most sunburn is not dangerous, but some signs need prompt attention. Please be seen without delay for widespread blistering, especially across the face or a large part of the body, a fever with chills, or signs of infection such as spreading redness, warmth, pus or increasing pain after a day or two. Confusion, fainting, a rapid heartbeat, severe dehydration, or a burn covering most of the body can signal a medical emergency, often alongside heat exhaustion, and mean you should go straight to a hospital emergency department.

Frequently Asked Questions
How do I know if my sunburn needs a doctor?
See a doctor if the burn covers a large area, blisters have formed, the skin is too painful to touch, or you feel feverish, dizzy or unwell. These signs suggest a deeper burn or heat illness that benefits from proper assessment rather than home care alone.
Does aloe vera actually help sunburn?
Yes, plain aloe vera gel soothes the heat and eases discomfort on mild burns. It is best used once the skin has cooled, and it does not replace medical care for blistered or widespread burns, which should be seen by a doctor.
Should I pop sunburn blisters?
No. Blisters protect the raw, healing skin underneath and popping them raises the risk of infection. Leave them intact, keep the area clean, and see us if they are large, spreading, or start to look infected.
Can sunburn make me feel sick all over?
Yes. A large burn can cause headache, chills, nausea, fatigue and dehydration, sometimes called sun poisoning. If you feel unwell in yourself, come in so we can rehydrate you and rule out heat exhaustion.
How long does sunburn take to heal?
A mild burn usually settles within three to five days, while a blistered burn can take a week or more and may peel as it heals. Keeping the skin moisturised, hydrated and out of the sun helps it recover more comfortably.
Do you make hotel or villa visits for sunburn?
Yes. If you are too sore to travel, our doctors visit hotels and villas across Chaweng, Bang Rak and Bophut. We bring what we need to assess and treat the burn where you are staying.
Will my travel insurance cover the visit?
We offer direct billing with most major travel insurers, so in many cases there is nothing to pay up front. Bring your policy details and passport, and our reception team will handle the paperwork for you.
