SunticHow to Treat Sunburn: After-Sun Care That Works
Sunburn is a sign that UV has already damaged your skin, and there is no way to undo it once it appears. What you can do is ease the discomfort, support your skin while it heals, and avoid making it worse. The advice below follows guidance from the American Academy of Dermatology and the Mayo Clinic. It is general information, not medical advice, and a bad burn always deserves professional care.
What are the first steps, as soon as you notice it?
The moment your skin starts to feel hot or look pink, act. The sooner you cool and soothe a burn, the more comfortable the next few days will be:
- Get out of the sun and stay out of it until the burn has healed.
- Cool the skin with a cool, not ice-cold, bath or shower, or a damp cloth held against the area for about ten minutes a few times a day.
- Moisturise while the skin is still damp, using a gel or lotion with aloe vera. Avoid products with added alcohol or fragrance, which can sting and dry the skin.
- Drink extra water. A burn draws fluid toward the skin surface, so you can dehydrate more easily.
- If you need it, an over-the-counter pain reliever such as ibuprofen taken early can reduce swelling and discomfort.
What should you do if the skin blisters?
Blisters mean a deeper, second-degree burn. Leave them alone. The American Academy of Dermatology advises against popping blisters, because the intact skin protects against infection and helps healing. If a blister bursts on its own, keep the area clean. As a burn heals it may peel, which is the body shedding damaged cells, so let it happen rather than picking at it.
Protect the burn while it heals
Sunburned skin is far more vulnerable to further UV, so going back out makes the damage worse and slows recovery. Until it has healed, stay in the shade and cover the area with clothing rather than relying on sunscreen over raw skin. Loose, tightly woven fabrics and a wide-brimmed hat do the job without irritation.
When should you get medical help?
Most sunburn can be managed at home, but some signs mean you should contact a doctor or, in severe cases, seek urgent care. The Mayo Clinic flags the following:
- A fever above 39.4C (103F), especially with vomiting.
- Severe pain, a bad headache, confusion, dizziness or feeling faint.
- Widespread blistering, or any blistering on the face, hands or genitals.
- Signs of infection such as increasing pain, swelling, redness, warmth or pus.
- Signs of dehydration, or eye pain and changes to your vision.
These can point to what is often called sun poisoning, a lay term for a severe reaction to UV and heat rather than a poisoning in the literal sense. When in doubt, get it checked.
The only real cure is prevention
Because sunburn cannot be reversed, avoiding it is the whole game. The most reliable way is to know when UV is strong and protect yourself before damage starts. Suntic shows the live UV index for your location and estimates a personalised safe-sun time from your skin type and SPF, so you get a heads-up well before your skin reaches its limit. Pair it with the practical steps in our sunburn prevention tips, and check how long you should stay in the sun to set your own limit.
Frequently asked questions
What is the best thing to put on sunburn?
A cool compress first, then a moisturiser or gel containing aloe vera while the skin is still damp. Avoid products with alcohol or fragrance, and avoid oily or petroleum-based products on a fresh burn. Drink extra water and take an over-the-counter pain reliever if needed.
Should I pop sunburn blisters?
No. Dermatologists advise leaving blisters intact, because the skin over them guards against infection and aids healing. If one bursts on its own, keep it clean. Blistering also means a deeper burn, so consider getting widespread blisters checked.
How long does sunburn take to heal?
A mild sunburn usually settles within a few days, while a more severe one with blistering can take a week or more. Cooling, moisturising, hydration and staying out of the sun all help. Seek medical care for fever, severe pain, extensive blistering or signs of infection.
