Sunburn pain typically starts within a few hours of sun exposure and peaks around 24 hours after the burn. That means the discomfort you’re feeling right now is likely still building, and acting quickly can make a real difference in how intense it gets. The fastest relief comes from cooling the skin, taking an anti-inflammatory painkiller, and keeping the burned area moisturized while your body repairs the damage.
Cool the Skin First
The single fastest thing you can do is apply something cool to the burn. Dampen a clean towel with cool tap water and lay it over the affected area for about 10 minutes. You can also step into a cool bath or shower. The goal is to pull heat out of the skin and slow the inflammatory process that’s driving the pain. Repeat this several times throughout the day, especially in the first 24 hours when inflammation is still ramping up.
Avoid ice or ice packs directly on the skin. Sunburned skin is already damaged, and extreme cold can injure it further. Cool water is enough.
Take an Anti-Inflammatory Painkiller
Over-the-counter anti-inflammatory painkillers like ibuprofen or naproxen do double duty for sunburn. They reduce pain and also tamp down the inflammation that causes swelling, redness, and tenderness. Taking one early, before the pain peaks, can blunt the worst of it. Follow the dosing instructions on the package, and keep up with regular doses for the first day or two rather than waiting until the pain returns each time.
Acetaminophen can help with pain but won’t address the inflammation, so it’s a less effective choice for sunburn specifically.
Apply Aloe Vera Gel
Aloe vera is the classic sunburn remedy for good reason. It contains fatty acids and an enzyme called bradykinin that calm irritated skin. Look for pure aloe vera gel rather than lotions that contain a small percentage of aloe mixed with fragrances and alcohol, which can sting and dry out the burn. Keeping the gel in the refrigerator adds a cooling effect that feels great on hot skin.
Apply a generous layer to the burned area and let it absorb. You can reapply as often as needed throughout the day. If you don’t have aloe on hand, a plain, fragrance-free moisturizer will help lock in moisture and reduce the tight, dry feeling that makes sunburn so uncomfortable.
Try a Colloidal Oatmeal Bath
For widespread burns covering your back, shoulders, or legs, soaking in a colloidal oatmeal bath can provide broad relief. Colloidal oatmeal contains natural compounds called avenanthramides that have both antioxidant and anti-inflammatory effects. The oat starches and beta-glucans attract water to your skin and form a protective barrier that helps lock in moisture. This barrier also shields damaged skin from irritants, reducing that raw, stinging sensation.
You can find colloidal oatmeal bath products at most drugstores. Add the powder to a lukewarm (not hot) bath and soak for 15 to 20 minutes. Hot water will intensify the burn, so keep the temperature comfortable.
Drink More Water Than Usual
Sunburn draws fluid toward the surface of your skin as part of the inflammatory response, which can leave the rest of your body mildly dehydrated. You may not feel especially thirsty, but dehydration makes headaches, fatigue, and general discomfort worse. Drink plenty of water in the hours and days following a burn. If you were also sweating heavily in the sun, a sports drink can help restore lost electrolytes and salt.
What to Avoid on Sunburned Skin
Some common “remedies” actually make sunburn worse. Petroleum jelly, butter, and oil-based products block pores, trapping heat and sweat beneath the skin. This can slow healing and increase the risk of infection. Products containing benzocaine, a topical numbing agent found in some sunburn sprays, can trigger allergic reactions in some people and worsen the burn.
Tight clothing, harsh soaps, and anything with fragrance or alcohol will also aggravate the pain. Wear loose, soft fabrics and wash the area gently with plain water or a mild cleanser until the burn heals.
What to Expect Over the Next Few Days
Pain from a sunburn starts within a few hours and gets progressively worse, peaking at about 24 hours after exposure. This means a burn you got at noon may not feel its worst until the following morning. After that peak, the pain gradually fades over the next two to three days for a mild to moderate burn.
Peeling typically begins a few days after the burn as your body sheds the damaged outer layer of skin. Resist the urge to peel it off, as pulling skin away prematurely can expose raw tissue underneath and increase infection risk. Keep the area moisturized and let the dead skin come off on its own.
Signs That Need Medical Attention
Most sunburns are painful but heal on their own. However, severe burns can cause symptoms that go beyond skin-deep discomfort. A fever above 101°F, chills, nausea, dizziness, or confusion after a sunburn suggest sun poisoning, which is your body’s systemic reaction to extensive UV damage. Large blisters covering a wide area, intense swelling, or signs of infection (increasing redness, warmth, pus, or red streaks spreading from the burn) also warrant a call to your doctor or a visit to urgent care.
