Sunburn pain typically peaks about 24 hours after exposure, so the burning sensation you’re feeling now may still be intensifying. The good news is that most of the relief strategies that actually work are simple, cheap, and available at home right now. Here’s what to do, why it works, and what to avoid.
Why Sunburn Hurts So Much
UV radiation damages skin cells, which triggers a cascade of inflammation. Your body responds by flooding the area with immune signals that cause redness, swelling, and heat. These same signals activate pain receptors in your skin that normally respond to heat and irritation, which is why sunburned skin feels hot to the touch and aches even when nothing is touching it. That’s also why gentle contact, like a shirt brushing against your shoulders, can feel genuinely painful. Your pain receptors are dialed up to maximum sensitivity.
This inflammatory process takes time to build. Pain usually starts within a few hours of the burn and keeps ramping up, hitting its worst point around 24 hours later. After that, it gradually fades over the next two to three days for a mild to moderate burn. Knowing this timeline helps: if you got burned this afternoon and the pain is already bad, it will likely get worse tonight before it starts improving.
Cool the Skin Down First
The single fastest way to reduce sunburn pain is a cool compress. Dampen a clean towel with cool tap water and lay it over the burned area for about 10 minutes. You can repeat this several times throughout the day. A cool shower works too, but keep it brief and gentle. The goal is to pull heat out of the skin and calm those overactive pain receptors.
Avoid ice or ice-cold water directly on the burn. Sunburned skin has a compromised barrier, and extreme cold can cause further damage or constrict blood flow your skin needs for healing. Cool, not cold, is the rule.
Moisturize While Skin Is Still Damp
After a cool compress or shower, pat your skin gently (don’t rub) and apply a moisturizer while your skin is still slightly damp. This locks in moisture at a time when your damaged skin barrier is losing water rapidly. That water loss contributes to the tight, stinging feeling and makes peeling worse later.
Aloe vera gel is a go-to for good reason. It’s naturally anti-inflammatory, which helps with redness and swelling. It contains antioxidants like vitamins C and E that reduce stress on damaged skin cells, and its high water content acts as a hydrating layer that may limit how much your skin peels in the days ahead. Look for pure aloe vera gel without added alcohol or fragrance, both of which will sting and dry out your skin further. If you have an aloe plant, fresh gel straight from a leaf works well.
Plain, fragrance-free moisturizers with ingredients like ceramides or hyaluronic acid are also effective. The key is keeping the skin hydrated. Avoid anything with retinol, glycolic acid, or other active ingredients that could irritate damaged skin.
Take an Anti-Inflammatory for Pain
Because sunburn pain is driven by inflammation, over-the-counter anti-inflammatory pain relievers like ibuprofen are more effective than acetaminophen for this specific type of pain. Ibuprofen addresses both the pain signals and the underlying inflammation causing them. Taking it early, before the pain peaks, can help blunt the worst of it.
If the burn covers a large area, a 1% hydrocortisone cream (available without a prescription) can reduce inflammation topically. Apply a thin layer to the burned area. This is especially helpful for spots where clothing rubs against the burn.
What Not to Put on a Sunburn
Some popular remedies make things worse. Petroleum jelly and heavy oil-based products trap heat in the skin, which is the opposite of what you want. Butter, coconut oil, and similar home remedies do the same thing.
Numbing sprays and creams containing lidocaine or benzocaine deserve particular caution. When applied to large areas of irritated or broken skin, lidocaine can absorb into the body at higher-than-expected levels. The FDA has warned that applying these products heavily over large skin areas, especially on irritated or broken skin, can lead to serious side effects including irregular heartbeat, seizures, and breathing difficulties. A sunburn covering your entire back or chest is exactly the kind of large, irritated skin area where this becomes risky. These products also sometimes cause allergic contact reactions on already-inflamed skin, adding a new problem on top of the burn.
Drink More Water Than Usual
A sunburn draws fluid toward the skin surface as part of the inflammatory response, which can leave the rest of your body mildly dehydrated. This is especially true for large burns or burns combined with a day of sun exposure where you were already sweating. Dehydration makes you feel worse overall and slows healing. Drink extra water for the next few days, and pay attention to signs like dark urine, headache, or dizziness.
Protect the Burn While It Heals
Loose, soft clothing made from breathable fabrics like cotton will cause the least friction against sensitive skin. If you have blisters, leave them intact. They’re your body’s natural bandage, protecting the new skin forming underneath. Popping them opens a path for infection and increases pain.
Stay out of the sun entirely until the burn has healed. Your skin is already damaged and far more vulnerable to additional UV injury. If you must go outside, cover the burned area with clothing rather than applying sunscreen directly to the burn, which can sting and irritate.
Signs That Need Medical Attention
Most sunburns, even painful ones, heal on their own within a week. But certain symptoms signal something more serious. Blisters covering a large portion of your body, fever, chills, nausea, or confusion suggest sun poisoning, a more severe reaction that needs medical care. If you notice any bleeding or oozing from the burn, that could indicate infection and warrants a prompt visit to your doctor. Severe swelling, especially on the face, or a burn in a young child also calls for professional evaluation.
