Sunburn Treatment and Aftercare in Arugam Bay: What Actually Helps

We see a lot of sunburn in this clinic, usually on day two or three of someone’s trip. The pattern is always the same: a long first session in the water, a nap on the beach afterward, and by evening the skin is hot, tight, and glowing red. Arugam Bay sits close enough to the equator that the sun catches people off guard even when they think they know what they’re doing. If you’re already burned, this article is about what actually helps now — not prevention, which we’ve covered elsewhere.

What’s happening to your skin

Sunburn is UV radiation damage to the outer layers of skin. It isn’t just cosmetic — it’s an inflammatory injury, similar in principle to a mild scald. Blood vessels near the surface dilate (which is why the skin looks red and feels hot), fluid leaks into the tissue (causing swelling and sometimes blistering), and nerve endings become irritated, which is where the pain and tenderness come from. Peeling a few days later is the skin shedding the damaged outer layer.

Redness usually peaks 12 to 24 hours after sun exposure, so a burn that looks moderate in the evening can look and feel considerably worse the next morning. Don’t judge severity based on how it looks right after you come off the beach.

What to do in the first few hours

• Get out of the sun immediately and stay out until the burn has settled, ideally a full day or two.
• Cool the skin. Cool (not ice-cold) showers, or a clean cloth soaked in cool water laid over the burn for 10 to 15 minutes, several times a day. Ice packs applied directly to burned skin can make things worse — always put a cloth between ice and skin.
• Hydrate aggressively. Sunburn draws fluid to the skin’s surface and away from the rest of your body, which can leave you dehydrated even if you haven’t been sweating much. Drink water steadily through the day, and add oral rehydration salts (ORS) if you’re feeling light-headed or the burn covers a large area.
• Take paracetamol or ibuprofen for pain and inflammation, at standard adult doses, unless you have a reason not to take one of them (kidney problems, stomach ulcers, or if you’re being treated for dengue, in which case avoid ibuprofen and any other NSAID).
• Moisturise once the initial heat has calmed down. Pure aloe vera gel is the standard choice and genuinely helps — it’s cooling, mildly anti-inflammatory, and doesn’t trap heat the way thick, greasy creams can. Keep a bottle in the fridge if you can; the coolness itself is soothing.

What not to do

• Don’t pop blisters. The blister roof is protecting new skin underneath from infection. If a blister bursts on its own, gently clean the area and cover it loosely — don’t peel the skin away.
• Don’t apply butter, toothpaste, or ice directly. All three are common local myths and all three can make a burn worse or introduce bacteria.
• Don’t use petroleum-based or heavily fragranced products on fresh sunburn. They can trap heat and irritate already-sensitive skin.
• Don’t go straight back in the sun the next day “because it feels better.” Burned skin has essentially no sun protection of its own for the next week or two, and a second burn on top of the first is significantly worse than either would have been alone.

Aftercare over the following days

Once the acute heat and pain have settled — usually a day or two — the priority shifts to keeping skin hydrated while it repairs itself.

• Keep applying aloe vera or a plain, fragrance-free moisturiser two to three times a day.
• Wear loose, breathable cotton clothing over affected areas. Tight or synthetic fabric rubbing against healing skin is uncomfortable and can delay recovery.
• Expect peeling from around day three to seven, depending on how deep the burn was. Resist the urge to pick at peeling skin — let it come away on its own.
• Stay well hydrated for the whole healing period, not just the first day. Skin repair takes water.
• Once you’re back in the sun, cover previously burned areas or use a high-SPF, reef-friendly sunscreen — that skin will burn more easily than usual for several weeks.

When to come and see us

Most sunburn is uncomfortable but manageable at home with the steps above. Come in if you notice any of the following:

• Large blisters, or blistering over a wide area of the body
• Fever, chills, headache, or nausea alongside the burn — this can indicate sun poisoning or heat illness rather than simple sunburn
• Signs of dehydration: dizziness, dark urine, or not urinating much
• Facial swelling, particularly around the eyes
• Signs of infection developing in a blistered area over the following days — increasing redness, warmth, pus, or worsening pain rather than gradual improvement
• Widespread pain that isn’t responding to paracetamol or ibuprofen
• A burn on a young child, especially an infant

We can assess the burn, give IV fluids if you’re significantly dehydrated, prescribe a stronger topical treatment for pain and inflammation if needed, and check for heat exhaustion or heat stroke, which sometimes travel alongside a bad sunburn after a long day out. If your symptoms feel serious, don’t wait it out — walk in any time, or call 1990 for a free ambulance.

A note for surfers

Sunburn on the back of the neck, shoulders, and the tops of the feet is extremely common after surf sessions, because these areas are exposed for hours and easy to forget when applying sunscreen. If you’ve burned one of these spots, a rash vest or long-sleeved layer for your next few sessions will protect it far better than sunscreen alone, since burned skin can make sunscreen application painful in the short term.
