You messed up. It happens to the best of us. Maybe you forgot to reapply after a swim, or perhaps you thought that "base tan" would protect you during a long hike in the high-altitude sun. Now, you’re lobster-red, your skin feels three sizes too small, and every time your shirt brushes against your shoulders, it feels like someone is holding a blowtorch to your back. You are scouring the internet for one specific answer: what should I put on sunburn to make the stinging stop?
First, breathe. The damage is done, and while you can't undo the DNA mutations currently happening in your skin cells, you can definitely manage the agony and prevent the dreaded "hell itch" or permanent scarring. Most people reach for the first green bottle they see at the pharmacy, but honestly, some of those "soothing" gels are packed with alcohol and fragrances that make things ten times worse. You need to be strategic. We're talking about a first-degree burn here—sometimes second-degree if you've got blisters—and your skin's moisture barrier is currently non-existent.
The Immediate Relief: What Goes on First?
Stop searching for a magic cream for a second and get in the shower. Not a hot one. God, no. You want cool water. Not ice-cold, either, because shocking your system can cause further stress to the tissue. Just cool. Stay in there for about 10 to 15 minutes. This helps pull the heat out of the skin. When you get out, do not rub yourself dry with a crusty towel. Pat gently. You want your skin to stay a little bit damp.

Now, for the actual topical application. Pure aloe vera is the gold standard for a reason. But here is the catch: it has to be pure. If you look at the ingredients of that neon-blue gel from the grocery store and see "Alcohol Denat" or "Lidocaine" near the top, put it back. Alcohol evaporates and dries out the skin, which is the exact opposite of what you want. Ideally, you’d have an actual aloe plant. Snap a leaf, squeeze the goo. If not, look for a brand like Seven Minerals or Amara Beauty that uses high percentages of organic aloe without the chemical fillers.
The Role of Soy and Colloidal Oatmeal
If you aren't an aloe fan, or it feels too sticky, look for moisturizers containing soy or colloidal oatmeal. Brands like Aveeno use these because they are naturally anti-inflammatory. Soy contains antioxidants that help stabilize the skin, while oatmeal creates a temporary barrier that locks in the water you just soaked up in the shower.
Is it greasy? A little. Does it work? Absolutely.
What Should I Put on Sunburn if it's Blistering?
This is where things get serious. If you see small, fluid-filled bubbles, you've crossed into second-degree burn territory. Do not pop them. I know it’s tempting. I know they look weird. But those blisters are a biological bandage. They are protecting the raw, new skin underneath from infection.
If a blister pops on its own, clean it with mild soap and water. You should put an antibiotic ointment, like Bacitracin or Polysporin, on the open area and cover it with a non-stick bandage. Avoid petroleum jelly (Vaseline) on a fresh, hot burn. Why? Because petroleum is an occlusive. It creates a heavy seal that can actually trap the heat inside your skin, making the burn simmer for longer. Save the thick salves for the peeling stage, not the "I'm currently on fire" stage.
The Kitchen Cabinet Myth-Busting
Let's talk about the weird stuff your grandma told you to use.
- Vinegar: Some people swear by apple cider vinegar mists to "balance pH." Honestly? It’s an acid. Putting acid on a burn is a gamble that usually ends in more irritation. Skip it.
- Butter: Never. Ever. It traps heat and can introduce bacteria. This is a 1950s myth that needs to die.
- Toothpaste: No. The menthol might feel "cool" for three seconds, but the calcium carbonate and detergents will dry out the skin and lead to cracking.
- Milk: Surprisingly, this one has some legs. A cool milk compress (soaking a clean cloth in whole milk and water) can help because the proteins (whey and casein) and fats help soothe the inflammation. The lactic acid also acts as a very, very gentle exfoliant later on, but mostly, it's about the cooling protein film.
Hydrocortisone: The Secret Weapon for Inflammation
Sometimes the pain isn't just a sting; it’s an all-encompassing itch and swell. When you're wondering what should I put on sunburn to actually stop the biological inflammatory response, reach for 1% hydrocortisone cream. You can get this over the counter. It's a low-dose steroid that tells your immune system to stop overreacting. It won't "cure" the burn, but it will significantly reduce the redness and the "tight" feeling.
Don't slather it over your whole body for days on end, though. Use it sparingly on the worst spots. If the itch is so bad you can't sleep—a phenomenon some call "Hell's Itch"—an oral antihistamine like Benadryl or Zyrtec is actually more effective than any cream.
Hydration is Internal, Too
Your skin is your largest organ. When it gets fried, it pulls fluid from the rest of your body to the surface to try and heal. This is why you often feel a headache, fatigue, or dizziness along with a bad sunburn. You are dehydrated.
Drink water. Then drink more. Toss in some electrolytes—Liquid I.V. or even just a Gatorade. If you're wondering what to put "on" the burn, remember that your blood flow is delivering the nutrients your skin needs to rebuild. If your blood is "thick" from dehydration, the healing process stalls.
Dealing with the Peeling Phase
A few days in, you’ll stop stinging and start peeling. It's gross. You’ll be tempted to peel the skin off in long strips like a snake. Resist the urge. Tearing off skin that isn't ready to come off exposes "immature" skin cells to the air, which can lead to permanent spotting (dyschromia) or infection.
Now is the time for the heavy-duty moisturizers. Look for ingredients like:
- Ceramides: (Found in CeraVe or La Roche-Posay) These help rebuild the skin barrier.
- Hyaluronic Acid: This molecule holds 1,000 times its weight in water.
- Vitamin E: A powerful antioxidant that helps with tissue repair.
When to See a Doctor
Most sunburns are a "wait it out" situation. However, if you develop a fever, chills, or severe nausea, you might have "sun poisoning" (photodermatitis). If the blisters cover more than 20% of your body—like your entire back and both arms—you need a professional. Doctors can prescribe stronger silver sulfadiazine creams that prevent infection and speed up cell turnover in a way OTC products just can't.
Summary of Actionable Steps
- Cool the skin immediately with a 15-minute lukewarm to cool bath or shower.
- Apply pure aloe vera gel or a soy-based moisturizer while the skin is still damp to lock in hydration.
- Take an NSAID like Ibuprofen (Advil/Motrin) as soon as you notice the burn. It reduces the actual swelling of the skin from the inside out.
- Wear loose, breathable fabrics like cotton or silk. Avoid polyester or tight spandex that traps sweat and heat against the damaged area.
- Stay out of the sun. It sounds obvious, but "re-burning" damaged skin is a fast track to scarring and a significantly higher risk of melanoma later in life.
- Use a 1% hydrocortisone cream for the areas that are particularly itchy or swollen, but avoid using it on open sores or broken blisters.
- Double your water intake for the next 72 hours to compensate for the fluid loss at the skin's surface.
The most important thing to put on a sunburn is actually patience. Your skin's outer layer (the epidermis) takes about a week to fully turn over. You can soothe the symptoms, but your body is the one doing the heavy lifting of repairing DNA damage and shedding dead cells. Next time, remember that a "base tan" is just a myth, and your skin remembers every single burn it has ever received. Keep the sunscreen handy and reapply every 90 minutes. For now, stay in the shade, keep the aloe in the fridge for an extra cooling kick, and let your body heal.
