The fastest way to relieve a sunburn is to cool the skin, take an anti-inflammatory pain reliever, and moisturize before the skin dries out. Most of the damage is already done by the time you feel it, but acting within the first few hours can significantly reduce pain, swelling, and peeling over the days ahead.
Cool the Skin Right Away
Your first move is getting heat out of the skin. Apply a clean towel dampened with cool tap water to the burned areas, or take a cool bath. Aim for about 10 minutes per session, and repeat several times throughout the day. Cool water constricts blood vessels near the surface and slows the inflammatory cascade that’s ramping up beneath your skin.
Avoid ice or ice-cold water directly on the burn. Sunburned skin is already damaged, and extreme cold can injure it further or cause vasoconstriction that slows healing. Room-temperature to slightly cool water is the sweet spot. If you’re coming straight from the beach or pool, get out of the sun first, then start cooling. Every additional minute of UV exposure deepens the burn.
Take a Pain Reliever Early
Ibuprofen is generally the best choice for sunburn pain. It blocks the production of prostaglandins, the chemicals your body releases in response to UV damage that cause redness, swelling, and tenderness. The key is timing: taking it early, ideally within the first few hours of noticing the burn, gives it the best chance to blunt the inflammatory response before it peaks. Naproxen and aspirin work through a similar mechanism.
Pain relievers won’t shorten how long your sunburn lasts, but they can make the worst 24 to 48 hours considerably more bearable. Sunburn inflammation typically peaks around 12 to 24 hours after exposure, so staying ahead of that wave matters more than treating it after the fact.
Moisturize While Skin Is Still Damp
After cooling the skin, pat yourself mostly dry and apply a moisturizer while there’s still some dampness. This locks in hydration at the surface and helps prevent the tight, cracking sensation that comes as burned skin dries out. Aloe vera gel is the classic option for good reason: it cools on contact and has mild anti-inflammatory properties. Moisturizing creams containing soy are also recommended by the American Academy of Dermatology for soothing irritated skin.
For more intense discomfort, a 1% hydrocortisone cream can reduce redness and itching. It’s available over the counter and safe for short-term use on sunburned skin.
One important thing to avoid: petroleum-based products and heavy oils. They trap heat in the skin rather than letting it dissipate, which can actually make a fresh sunburn feel worse and slow the cooling process. Also steer clear of any product with “-caine” ingredients like benzocaine. These topical anesthetics sound helpful, but they can irritate damaged skin or trigger allergic reactions.
Drink More Water Than Usual
Sunburn draws fluid toward the skin’s surface as part of the inflammatory response. A severe burn can cause enough fluid loss through the damaged skin barrier to contribute to dehydration, especially if you were already sweating in the sun for hours before noticing the burn. You won’t find a specific “drink X extra ounces” guideline because it depends on the severity and how much of your body is affected, but the principle is straightforward: drink water consistently for the next couple of days, more than you normally would. If your urine is dark or you feel lightheaded, you’re behind.
Leave Blisters Alone
If your sunburn is bad enough to blister, those fluid-filled pockets are actually protecting the raw skin underneath while new tissue forms. Popping or peeling them opens the door to infection and slows healing. Leave intact blisters alone and let them resolve on their own.
If a blister breaks on its own, gently trim the dead skin with clean, small scissors. Wash the area with mild soap and water, apply an antibiotic ointment, and cover it with a nonstick bandage. Keep an eye on it for signs of infection like increasing redness, warmth, or pus.
What to Expect as It Heals
A mild sunburn (pink skin, some tenderness, no blisters) typically resolves in 3 to 5 days. You might see light peeling near the end as the damaged outer layer sheds. A moderate burn with more noticeable pain and swelling can last about a week, with deeper peeling. Severe sunburns with blisters, intense pain, or systemic symptoms like chills can stick around for 10 days or longer.
During the peeling phase, resist the urge to pull or pick at flaking skin. It’s tempting, but pulling can tear healthy skin underneath before it’s ready. Keep moisturizing and let it shed naturally. Wear loose, soft clothing over burned areas, and stay out of the sun entirely until the skin has fully healed. Burned skin is dramatically more vulnerable to additional UV damage.
Signs That Need Medical Attention
Most sunburns are miserable but manageable at home. However, a severe burn can cross into territory that requires a doctor. Seek medical care if your sunburn comes with blisters covering a large area of your body along with any of these symptoms: fever, shivering or feeling extremely cold, severe pain that isn’t responding to over-the-counter medication, headache, nausea or vomiting, or bright red skin that’s oozing. These signs suggest sun poisoning, a more serious reaction that can involve systemic inflammation and significant fluid loss.
