You can’t undo a sunburn, but you can significantly reduce the pain, redness, and peeling by acting quickly in the first 24 hours. Sunburn pain typically starts within a few hours of UV exposure and peaks at about 24 hours, so the sooner you begin cooling and moisturizing your skin, the more comfortable your recovery will be. Mild to moderate sunburns generally heal within about seven days.
Cool Your Skin Immediately
The single most effective first step is getting your skin temperature down. Take a cool bath or apply cool, damp cloths to the burned areas for about 10 minutes at a time, several times throughout the day. Don’t use ice or ice water directly on the burn, which can shock already-damaged skin. You want the water to feel refreshingly cool, not cold enough to make you flinch.
If you’re using a compress, re-wet it frequently. A warm, damp cloth sitting on a sunburn does nothing. After each cooling session, gently pat your skin dry rather than rubbing, which irritates the damaged surface.
Choose the Right Moisturizer
Moisturizing burned skin does more than soothe the sting. Sunburn breaks down your skin’s lipid barrier, the protective layer that holds moisture in and keeps irritants out. Without that barrier intact, your skin loses water rapidly, which increases pain, tightness, and eventual peeling.
Look for moisturizers containing ceramides, which are lipids that fill in the gaps left by UV damage and help rebuild the barrier faster. Hyaluronic acid is another strong ingredient for recovery. It can hold up to 1,000 times its weight in water and pulls moisture from the air into your skin, providing lasting hydration that speeds healing.
Aloe vera works, but concentration matters. A small study found that 97.5% aloe vera gel reduced UV-induced redness, while a 70% aloe vera cream showed no effect. The active compound in aloe, called aloin, has anti-inflammatory and antioxidant properties. So if you’re reaching for an aloe product, look for one with a very high aloe concentration rather than a lotion that lists aloe as a minor ingredient. Soy-based moisturizers are another option recommended by the Skin Cancer Foundation for soothing burned and peeling skin.
Ingredients to Avoid
Stay away from petroleum-based products like Vaseline on a fresh sunburn. Petroleum traps heat in the skin and can make the burn worse. Also skip anything containing benzocaine or lidocaine. While these numbing agents sound appealing when you’re in pain, they can irritate already-damaged skin and cause allergic reactions. Stick with cooling, hydrating products instead.
Manage Pain and Inflammation
Because sunburn is fundamentally an inflammatory response, over-the-counter anti-inflammatory pain relievers can help reduce both swelling and discomfort. Taking one early, before the pain peaks at the 24-hour mark, gives you a head start on controlling the inflammatory cascade. Your body is sending immune cells to the damaged area to repair what it can and clear out dead cells, and that immune activity is what creates the redness, heat, and tenderness you feel.
For severe discomfort, a cool bath combined with an anti-inflammatory creates a layered approach: the bath addresses surface heat while the medication works on the deeper inflammatory process.
Drink More Water Than Usual
Sunburn draws fluid to the skin’s surface and away from the rest of your body, which can leave you mildly dehydrated even if you don’t feel thirsty. This is especially true with widespread burns covering your back, shoulders, and chest. Drink extra water throughout your recovery. If you had significant sun exposure and feel headachy, dizzy, or nauseous, those are signs of dehydration or heat-related illness that need more aggressive fluid replacement.
How to Handle Peeling
Peeling is your body shedding cells too damaged to repair. It’s a necessary part of healing, and you cannot fully prevent it once the damage is done. What you can do is minimize it and keep yourself comfortable while it happens.
Do not pull off peeling skin or scrub it with an exfoliant. Pulling exposes raw, sensitive skin underneath before it’s ready, increasing your risk of infection and scarring. Let the dead skin slough off naturally. Continue moisturizing throughout the peeling phase, which helps the process move faster and keeps the new skin underneath hydrated and protected. Peeling from mild to moderate burns typically stops within about seven days, once the burn has fully healed.
Protect Your Skin While It Heals
Burned skin is dramatically more vulnerable to further UV damage. While you’re healing, cover the affected areas with loose-fitting clothing whenever you go outside. Tight fabrics will rub against the burn and cause pain, so choose something that drapes without pressing against your skin. Breathable, moisture-wicking fabrics will keep you most comfortable.
If your burned skin will be exposed to the sun, look for clothing with a UPF rating of 50, which blocks about 98% of UV rays. Tightly woven fabrics in dark or bright colors offer the best protection. If you only have lighter clothing, a laundry additive called Rit SunGuard can boost a garment’s UPF to 30. Applying sunscreen over a healing burn is better than nothing, but fabric coverage is gentler and more reliable while your skin is still sensitive.
What Won’t Work
A few popular home remedies either don’t help or actively make things worse. Butter, coconut oil, and other heavy oils trap heat the same way petroleum does. Vinegar and lemon juice are acidic and can sting or further irritate damaged skin. Toothpaste, sometimes suggested online, contains menthol that creates a cooling sensation but dries out the burn.
There’s also no topical product that will make a sunburn disappear overnight. Your skin needs time to clear damaged cells and regenerate. The strategies above compress that timeline as much as biology allows, but a burn that would take a week to heal on its own will still take several days with good care. The real difference is in how it feels during that time: properly cooled, moisturized, and protected skin is far less painful and peels less dramatically than skin left to fend for itself.
