You messed up. You stayed out at the lake ten minutes too long, or you forgot that the "water-resistant" label on your SPF 30 doesn't mean it’s invincible against a three-hour swim. Now, your shoulders feel like they’re vibrating, your skin is a shade of neon pink that shouldn't exist in nature, and you’re wondering how to stop sunburn pain before you lose your mind. It’s miserable.
Honestly, most people treat a sunburn like a minor annoyance, but it’s actually a radiation burn. Your DNA has been damaged by UV rays, and your immune system is currently screaming at your brain. The heat you feel radiating off your skin? That’s vasodilation. Your body is pumping blood to the surface to try and repair the wreckage.
If you want the pain to stop, you have to stop fighting your body’s inflammatory response and start supporting it.
Why your skin feels like it’s on fire
The sting isn't just "the sun." It’s a complex chemical cascade. When those ultraviolet rays hit your skin cells, they break down the cellular structure. Your body responds by releasing inflammatory mediators—prostaglandins and bradykinin—which sensitize your nerve endings. That is why even a light breeze or the touch of a cotton t-shirt feels like someone is rubbing your back with sandpaper.
Most people reach for the first bottle of green goo they find at the drugstore. Stop. If that "aloe" gel contains lidocaine or benzocaine, you might actually be making things worse. While these numbing agents provide a momentary "ahhh" feeling, they are notorious for causing allergic reactions on already compromised skin. A localized rash on top of a second-degree burn is a special kind of hell you want to avoid.
The immediate cooling phase
First things first: get out of the heat. This sounds obvious, but the damage continues even after you go indoors if your skin temperature stays elevated. You need to pull the heat out of the tissue.

Forget ice.
Putting ice directly on a sunburn can cause a cold burn (frostbite) on top of the heat burn because your skin’s natural defenses are already down. Instead, take a cool bath or shower. Keep the water temperature just below lukewarm. You aren't trying to induce hypothermia; you're just trying to bridge the gap between "burning" and "room temperature."
Once you hop out, don't rub yourself dry. Pat. Seriously, just barely touch the towel to your skin. You want to leave a little bit of moisture on the surface. This is the "golden window" for moisturizing. If you apply lotion to bone-dry, parched skin, you’re just coating the problem. If you apply it to damp skin, you trap that hydration in.
Choosing the right topical relief
Aloe vera is the gold standard for a reason, but it has to be the right kind. Look at the ingredient list on the back of the bottle. If the first ingredient is water and the second is "Alcohol Denat," put it back. Alcohol evaporates quickly, which feels cool for three seconds but then sucks the remaining moisture out of your skin, leading to more peeling and more pain.
You want 100% pure aloe vera. Or, better yet, break a leaf off an actual plant if you have one. The acemannan in aloe is what actually does the heavy lifting for wound healing.

Another weirdly effective trick? Soy-based moisturizers. Brands like Aveeno use soy because it helps reduce redness and has been shown in some small clinical observations to calm the "stinging" sensation faster than standard petroleum-based jellies. Avoid anything heavy like Vaseline in the first 24 hours. Heavy ointments can actually trap the heat inside the skin, essentially "cooking" the tissue for longer.
The internal battle: Meds and hydration
You can’t just treat this from the outside. The pain of a sunburn is driven by those prostaglandins I mentioned earlier.
Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (Advil, Motrin) or naproxen (Aleve) are your best friends here. They don't just dull the pain; they actually inhibit the enzymes that create the inflammation in the first place. If you take them early enough—ideally within the first hour of noticing the redness—you can significantly dampen the overall severity of the burn.
Then there is the water situation.
A sunburn "draws" fluid to the skin’s surface and away from the rest of your body. You are functionally dehydrated the second that burn appears. If you’re feeling a headache or fatigue alongside the skin pain, you’re likely dealing with mild heat exhaustion. Drink water. Then drink more. Add an electrolyte powder if you’ve been sweating, because plain water won't replace the salts you lost while you were getting fried.

Dealing with the "Hell's Itch"
If you’ve never had it, count your blessings. If you have, you know it’s the deep, maddening itch that sets in about 48 to 72 hours after the burn. It feels like fire ants are crawling under your skin.
When people ask how to stop sunburn pain during this phase, the answer changes from "cool it down" to "don't touch it." Scratching will lead to scarring and potential infection.
- Antihistamines: Take an oral antihistamine like Benadryl or Zyrtec. It helps settle the histamines that trigger that deep-seated itch.
- Hydrocortisone: A 1% hydrocortisone cream can help, but use it sparingly. It’s a steroid, so it calms the immune response.
- Colloidal Oatmeal: A lukewarm bath with finely ground oatmeal (like Aveeno’s bath treatment) creates a protective barrier that can stop the itching for a few hours at a time.
When to see a doctor
Most burns are first-degree, meaning they only affect the epidermis. But if you see blistering, you’ve hit second-degree territory.
Do not pop the blisters. I know it’s tempting. I know they look weird. But that blister is a sterile "biological bandage" that your body created to protect the raw skin underneath. If you pop it, you open a doorway for staph infections.
If the blisters cover a large portion of your body, or if you start running a high fever, experiencing chills, or feeling confused, get to an urgent care. This isn't a "tough it out" situation; it’s a systemic inflammatory response that might require IV fluids or specialized burn dressings.
The long-term recovery
Once the pain subsides, the peeling begins. This is your body’s way of getting rid of cells that were damaged so badly they might become cancerous. It’s a safety mechanism.
Don't peel the skin yourself. Let it fall off naturally. If you rip it off too early, you expose "new" skin that isn't ready for the world, leading to more pain and potential permanent discoloration (dyschromia). Keep moisturizing with a fragrance-free, bland cream like CeraVe or Eucerin to keep the skin barrier as intact as possible.
Actionable steps for immediate relief
- Get out of the sun immediately and stay in a cool, shaded environment.
- Take an NSAID (ibuprofen) as soon as possible to block the inflammatory cascade.
- Cool the skin with a 10-15 minute lukewarm shower or cool compresses.
- Apply pure aloe vera or a soy-based moisturizer while the skin is still damp.
- Hydrate aggressively with water and electrolytes to counteract the fluid shift.
- Wear loose, breathable clothing—ideally silk or very soft cotton—to minimize friction on the nerve endings.
- Leave blisters alone to avoid infection and scarring.
