Cool water, aloe vera, and an over-the-counter anti-inflammatory pain reliever are the core tools for treating a sunburn at home. Most sunburns heal within one to two weeks with proper care, but the first 24 hours matter most for limiting pain and skin damage. Here’s what works, what to skip, and how to move through each stage of recovery.
Cool the Skin First
Before you reach for any product, bring the temperature of your skin down. Dampen a clean towel with cool tap water and hold it against the burned area for about 10 minutes. You can repeat this several times throughout the day. A cool bath works too. Adding roughly two ounces (about a quarter cup) of baking soda to the tub can help soothe irritation further.
Avoid ice or ice-cold water directly on the skin. Sunburned skin is already damaged, and extreme cold can constrict blood flow and make things worse. Room-temperature to slightly cool water is the target.
Aloe Vera for Pain and Healing
Aloe vera is the most widely recommended topical treatment for sunburn, and the science supports it. The gel contains active compounds that reduce inflammation by dialing down the body’s inflammatory signaling pathways. In animal studies, these compounds shortened wound healing time for burns. That anti-inflammatory effect is what makes aloe feel so immediately soothing on hot, tender skin.
Look for pure aloe vera gel rather than products that add fragrances, alcohol, or dyes, all of which can sting or further irritate damaged skin. If you have an aloe plant, splitting a leaf and applying the gel directly works well. Keep the gel in the refrigerator for an added cooling effect. Apply it generously several times a day, especially during the first two to three days when inflammation is building.
Take a Pain Reliever Early
Ibuprofen or aspirin can help reduce both the pain and redness of a sunburn, but timing matters. Studies show these anti-inflammatory medications are most effective when taken soon after sun exposure, ideally before the redness fully develops. Their benefit peaks around six hours after UV exposure. By the time a sunburn is at full intensity (usually around 24 hours), the window for maximum anti-inflammatory effect has largely passed.
That said, even taken later, ibuprofen still helps with pain management. The key takeaway: if you realize you’ve been overexposed, don’t wait for the burn to get bad before taking something.
Moisturize as the Burn Heals
Sunburn strips moisture from your skin and disrupts its protective barrier. Once the initial heat has calmed (usually after the first day or two), switching from aloe to a richer moisturizer helps your skin recover faster. Ceramide-containing moisturizers are particularly effective here. Ceramides are lipids that naturally exist in your skin’s outer layer, and formulations containing them have been shown to reduce redness and discoloration, improve hydration, and help skin cells maintain normal turnover after UV damage.
Apply moisturizer while your skin is still slightly damp from a shower or bath to lock in hydration. Fragrance-free formulas are safest for irritated skin. You’ll want to keep moisturizing consistently for at least a week, even after the visible redness fades, because the barrier damage lasts longer than the sunburn looks.
Colloidal Oatmeal for Itching
As a sunburn heals, itching often becomes more bothersome than pain. This is where colloidal oatmeal shines. Available as a bath soak or in lotions, colloidal oatmeal works by calming cytokines, the inflammatory proteins responsible for skin itchiness and redness. It also acts as a skin protectant, forming a soothing layer over irritated areas.
An oatmeal bath is especially useful during the peeling stage, which typically starts around day three to five. You can find colloidal oatmeal bath packets at most drugstores. Dissolve one in a lukewarm bath and soak for 15 to 20 minutes.
Drink More Water Than Usual
Sunburn pulls fluid toward the skin’s surface as part of the inflammatory response, which can leave the rest of your body mildly dehydrated. Increase your water intake for several days after a significant burn. Watch for signs of dehydration like fatigue, dry mouth, and reduced urine output. This is easy to overlook but makes a real difference in how you feel during recovery.
What Not to Put on a Sunburn
Several products that seem like they’d help actually make things worse. Topical anesthetics containing benzocaine or lidocaine are sold specifically for sunburn relief, but they carry a meaningful risk of allergic skin reactions. Benzocaine is the most common culprit, causing contact dermatitis in a significant number of people, with lidocaine close behind. These products can turn a simple sunburn into a red, itchy rash that’s worse than what you started with.
Also avoid petroleum jelly, butter, or any thick, greasy product during the acute phase. These trap heat in the skin. Alcohol-based aftershaves or astringents dry out already-compromised skin and increase irritation.
Leave Blisters Intact
If your sunburn blisters, resist the urge to pop them. An intact blister acts as a natural bandage, protecting the raw skin underneath while it heals. If a blister breaks on its own, gently trim away the dead skin with clean scissors, wash the area with mild soap and water, apply an antibiotic ointment, and cover it with a nonstick bandage to prevent infection.
Blistering signals a deeper burn. Pain from a sunburn typically peaks at about 24 hours, and over the following week your skin will peel and gradually return to its normal color. Severe sunburns with extensive blistering can take several weeks to fully heal.
When a Sunburn Needs Medical Attention
Most sunburns are uncomfortable but manageable at home. However, extensive blistering over a large portion of your body is a different situation. When blisters cover more than about 20% of an adult’s skin surface (roughly the equivalent of both legs), there’s a real risk of fluid and electrolyte loss that may require medical treatment. A sunburn that initially looks superficial can also progress into deeper tissue damage over the first day or two. Fever, chills, nausea, or feeling faint alongside a bad sunburn are signs your body is struggling with the systemic effects and you should seek care.
