How to Treat a Sunburn: What Actually Helps (and What Makes It Worse)

There's an uncomfortable truth at the centre of sunburn care: by the time your skin turns red, the damage is already done. A sunburn is UV injury to the skin — the redness, heat, and peeling are the aftermath, not the event. So "treating" a sunburn isn't about reversing it; it's about calming the symptoms and supporting your skin while it repairs itself over the next few days.

That reframing matters, because it explains why the goal is comfort and barrier support rather than a miracle fix — and why a few popular "remedies" actively slow things down.

You can't undo a sunburn, only ease it. Cool the skin, hold in moisture, calm the inflammation, and hydrate from within — while avoiding the handful of things that trap heat or tear healing skin.

What actually helps

Dermatologists converge on a short, unglamorous list:

• Cool it down. A cool (not ice-cold) bath or shower brings skin temperature down and eases inflammation. Keep it short — long soaks dry the skin further — and use gentle water pressure. For a smaller area, a cool, damp compress works.
• Moisturise on damp skin. Pat dry (don't rub), leave the skin slightly damp, and apply a moisturiser to lock in water. Formulas with aloe vera or soothing lipids calm the burn; a colloidal oatmeal bath can settle inflammation too.
• Bring down the inflammation. An over-the-counter anti-inflammatory such as ibuprofen can reduce swelling, redness, and pain, and is most useful started early.
• Hydrate. A burn pulls fluid toward the skin's surface and away from the rest of the body, so drink extra water while you heal.
• For itch, a thin layer of 1% hydrocortisone cream can help — but don't scratch, which risks infection.

The through-line is barrier support: UV compromises the skin barrier, so keeping it cool, moist, and undisturbed is what lets it recover.

What makes it worse

Just as important is what to stop doing:

• Don't peel or pick. Flaking is the skin shedding its damaged top layer — pulling it off invites scarring and infection. Dermatologists genuinely plead with people about this one.
• Don't pop blisters. A blister means a second-degree burn; the intact skin over it is protecting you. Let it heal on its own. (Only after a blister has drained on its own should you keep it clean and cover it.)
• Skip thick ointments and petroleum jelly on a fresh burn — they can trap heat in already-overheated skin.
• Avoid "-caine" anaesthetics (benzocaine, lidocaine) and alcohol-based products — the first can trigger allergic reactions, the second dries the skin further.
• No ice directly on the skin, and no exfoliating the burned area.

When a sunburn needs a doctor

Most sunburns, even with a few small blisters, heal at home. Seek medical care if you have: blistering over a large area of the body; a high fever, chills, severe pain, headache, confusion, or nausea (possible signs of "sun poisoning" or heat illness); signs of infection (spreading redness, pus, red streaks); or blisters on the face, hands, or genitals. Eye pain or vision changes after sun exposure also warrant attention.

The part that actually matters

There's no treatment that makes a sunburn worth it, because the damage is cumulative and permanent at the cellular level — and just five sunburns are associated with roughly double the lifetime risk of melanoma. So the real "treatment" is the next one you prevent: broad-spectrum sunscreen, shade, and protective clothing. Aftercare eases today's burn; prevention protects the skin you'll have for decades.

Frequently asked questions

Can you get rid of a sunburn quickly? No. Once skin is burned, the damage is done, and it heals on its own timeline over several days. Treatment eases symptoms — cooling, moisturising, anti-inflammatories, and hydration — but doesn't reverse the burn.

What should I put on a sunburn? Apply a moisturiser to damp skin, ideally with aloe vera or soothing lipids, and use cool compresses. A 1% hydrocortisone cream can help with itch. Avoid petroleum jelly on a fresh burn and any "-caine" numbing products.

Should I pop sunburn blisters? No. A blister indicates a second-degree burn, and the skin over it protects against infection. Let blisters heal on their own; if one drains, keep it clean and covered.

Why shouldn't I peel my sunburn? Peeling skin is your body shedding its damaged top layer. Pulling it off can cause scarring and infection — let it flake away naturally and keep the area moisturised.

When should I see a doctor for a sunburn? If you have widespread blistering, fever, chills, severe pain, confusion, or nausea, or signs of infection like pus or spreading redness. Blisters on the face, hands, or genitals also warrant medical care.

Does a sunburn always turn into a tan? A tan is itself a sign of UV damage, not "recovery." There's no safe UV tan, and a burn is more damage, not a stepping stone to a healthy one.

This article is educational and covers general self-care for mild sunburn; it isn't medical advice. Severe, blistering, or widespread burns — or a burn with fever or signs of infection — should be assessed by a healthcare professional.
