A mild to moderate sunburn responds well to a combination of cooling, moisturizing, hydrating, and managing pain. Most sunburns heal on their own within a week or two, but the right care in the first 24 to 48 hours can significantly reduce discomfort and help your skin recover faster.
Cool the Skin First
The single best thing you can do immediately is bring down the temperature of your skin. A cool (not cold) shower or bath works well, or you can press a damp cloth against the burned areas for 10 to 15 minutes at a time. Ice packs or ice directly on the skin can cause further damage, so stick with cool water.
Adding colloidal oatmeal to a lukewarm bath is another effective option. Oats contain compounds called avenanthramides, which have potent anti-inflammatory effects. They work by dialing down the same inflammatory signaling pathways your body ramps up after UV damage. Soak for 15 to 20 minutes, pat dry gently, and follow up with a moisturizer while your skin is still slightly damp.
Aloe Vera and Moisturizers
Aloe vera gel is the classic sunburn remedy for a reason. Animal research has confirmed that its active components shorten wound healing time and reduce inflammation by calming the same cellular pathways involved in the burn response. Look for pure aloe vera gel (ideally from the refrigerator for extra cooling relief) or a lotion with aloe as a primary ingredient. Calamine lotion is another soothing option, especially if itching is a major symptom.
Whatever moisturizer you choose, apply it while your skin is still slightly damp to lock in hydration. Reapply several times a day as the burn heals. Avoid products containing alcohol, which dries out already damaged skin. Also steer clear of any product with “-caine” ingredients like benzocaine. These topical anesthetics can irritate sunburned skin or trigger an allergic reaction, making things worse.
Pain Relief That Actually Helps
Take an over-the-counter anti-inflammatory like ibuprofen as soon as possible after getting burned. NSAIDs don’t just dull the pain. They reduce the inflammatory cascade happening in your skin, which can limit how red and swollen the burn becomes. Acetaminophen helps with pain but won’t address the inflammation itself. Starting early matters: the inflammatory response peaks in the first 24 hours, so taking a pain reliever right away gives you the most benefit.
Drink More Water Than You Think
Sunburn draws fluid toward the surface of your skin and away from the rest of your body. Damaged capillaries become more permeable, leaking fluid into surrounding tissue for roughly 24 hours after the burn. This is why even a moderate sunburn can leave you feeling tired, headachy, or just “off.” You’re mildly dehydrated even if you don’t feel thirsty. Drink extra water and consider beverages with electrolytes in the days following a burn, especially if you were also sweating in the sun.
What to Do About Blisters and Peeling
If your sunburn blisters, leave them intact. Blisters are your body’s natural bandage, protecting the raw skin underneath while new cells form. Popping them invites infection. If a blister breaks on its own, gently clean the area and apply a light layer of petroleum jelly or aloe before covering with a non-stick bandage.
Peeling typically begins a few days after the initial burn as your body sheds the damaged outer layer of skin. It’s tempting to pull at it, but peeling skin prematurely can expose skin that isn’t ready and increase the risk of scarring or discoloration. Let it shed naturally and keep the area moisturized.
What Not to Use
A few common remedies can actually slow healing or cause additional irritation:
- Butter, coconut oil, or other heavy oils: These trap heat in the skin and can worsen the burn.
- Alcohol-based products: Including aftershave and many “cooling” sprays. They dry out the skin further.
- Benzocaine sprays or creams: Despite being marketed for burns, they can cause allergic reactions on compromised skin.
- Harsh exfoliants or scrubs: Your skin is already shedding damaged cells. Scrubbing increases irritation and delays repair.
Signs a Sunburn Needs Medical Attention
Most sunburns are painful but manageable at home. However, severe burns can become a medical emergency. Seek immediate care if you have blisters covering more than 20% of your body (roughly an entire leg, your whole back, or both arms), a fever above 102°F, or signs of dehydration like dizziness, dry mouth, and reduced urination.
Watch for symptoms of heat illness as well, which can overlap with a bad sunburn: confusion, rapid breathing, muscle cramps, nausea, or shivers. These suggest your body is struggling to regulate its core temperature and needs professional help.
Protecting Your Skin While It Heals
Freshly burned skin is far more vulnerable to additional UV damage. Wear loose, tightly woven clothing over the burned area whenever you’re outside, and avoid direct sun exposure until the redness and tenderness are completely gone. If you must be outdoors, use a broad-spectrum sunscreen with SPF 30 or higher on any exposed, unburned skin. Burned skin that’s still healing is best covered with clothing rather than sunscreen, since the chemicals in sunscreen can irritate the damaged barrier.
New skin that forms after peeling is especially sensitive and will burn more quickly for several weeks. Continue to protect it with clothing or sunscreen even after the burn itself has resolved.
