You messed up. It happens. Maybe you forgot to reapply after a swim, or perhaps you thought that "base tan" would protect you during a three-hour hike. Now, your skin is radiating heat like a ceramic kiln, and every time your shirt brushes against your shoulders, you want to jump out of your own body. It hurts. It’s tight. And honestly, it’s a bit embarrassing.
But here is the thing about learning how to calm sunburn: most people actually make it worse by reaching for the wrong remedies too quickly. They slather on heavy goops that trap heat or use "natural" fixes that irritate the skin further. Your skin is literally cooked. You have to treat it like a thermal burn, not just a temporary redness.
The damage is done at a cellular level. UV radiation has essentially scrambled the DNA in your skin cells, and your body is currently launching a massive inflammatory response to deal with the wreckage. This isn't just a surface issue; it's a systemic one.
Stop the Heat Before You Do Anything Else
The first thing you need to do—right now—is get the temperature down. Your skin is holding onto heat. If you don't dissipate that heat, the "cooking" process continues deeper into the dermis.
Jump in a cool shower. Not ice cold. Just cool. If the water pressure feels like needles, don't stand directly under the spray; let it hit your chest and run down over the burned areas. You’ve got to be gentle.
When you get out, do not rub yourself dry. This is a common mistake. Pat yourself very lightly with a soft towel, leaving just a little bit of moisture on the skin. Why? Because that moisture is your best friend when you apply your first layer of relief.

The Aloe Trap and What to Use Instead
We’ve all been told that aloe vera is the holy grail. It is, but only if it’s the right kind. Most of the bright green "aloe" gels you find in drugstore aisles are packed with lidocaine, alcohol, and artificial fragrances. Alcohol evaporates and dries out the skin, which is the last thing you want. Lidocaine can actually trigger an allergic reaction on compromised skin.
If you have a plant, use that. Cut a leaf, scrape out the clear goo, and apply it. If you’re buying it, look for a label that says 100% pure aloe and check the ingredient list for "Tocopheryl Acetate" (Vitamin E), which helps stabilize the skin barrier.
But let’s talk about the real heavy hitters.
Hydrocortisone cream (1%) is a game-changer if you use it in the first 24 hours. It’s a low-dose steroid that shuts down the inflammatory signaling. It stops the swelling before it gets out of hand. Combine that with a thick, bland moisturizer. Think CeraVe or Vanicream. You want something with ceramides. Ceramides are the lipids that act like the "mortar" between your skin cell "bricks." Your mortar is currently crumbling. You need to replace it manually.
Hydration is Not Just for Your Skin
You’re dehydrated. I can almost guarantee it.

When you have a sunburn, your body pulls fluid to the surface of the skin to try and cool it down. This takes water away from the rest of your body. If you feel a headache coming on or you’re feeling slightly dizzy, that’s not just the sun—it’s fluid loss.
Drink water. Then drink more. Skip the margaritas for tonight; alcohol is a diuretic and will only make the skin's recovery slower. You need electrolytes too. A Gatorade or a Pedialyte isn't overkill here. Your cells need the salt and potassium to hold onto the water you're chugging.
Dealing with the Blister Phase
If you see blisters, you’ve hit second-degree burn territory.
Do not pop them.
Those blisters are nature’s Band-Aids. The fluid inside is sterile, and the skin over the top is protecting the raw, new tissue underneath from infection. If you pop them, you open a doorway for bacteria. If they pop on their own, don't peel the skin away. Apply an antibiotic ointment like Bacitracin (not Neosporin, as many people are allergic to the neomycin in it) and cover it loosely with a non-stick gauze.

If the blisters cover a large area—like your entire back—or if you start running a fever and getting chills, you need to go to Urgent Care. This is called "sun poisoning" (polymorphous light eruption or just severe systemic inflammation), and you might need prescription-strength anti-inflammatories.
The Weird Stuff That Actually Works
There are a few "kitchen" remedies that dermatologists actually stand by, though they sound like old wives' tales.
- Milk Compresses: Cold milk contains proteins and vitamins that can soothe the sting, and the lactic acid can help very gently with the eventual peeling. Soak a washcloth in cold milk and water (50/50) and lay it on the burn for 10 minutes.
- Oatmeal Baths: Not the flavored breakfast kind. Use colloidal oatmeal (Aveeno makes a great one). It’s basically finely ground oats that suspend in water. It creates a protective film over the skin and is incredibly anti-itch.
- Green Tea: Cold, brewed green tea applied with a spray bottle contains polyphenols that can reduce the severity of the UV damage after the fact. It won't "undo" the burn, but it can dampen the fire.
What to Wear While You Heal
Basically, you want to be a ghost.
Wear loose, breathable cotton or silk. Avoid synthetics like polyester that trap sweat. Sweat is salty, and salt on a fresh burn feels like... well, salt on a wound. If you have to go back outside, you cannot rely on sunscreen alone for the next week. Your skin is too sensitive for most chemical filters right now. Use physical barriers: wide-brimmed hats, UPF-rated clothing, or just stay in the shade.
The Long Game: Preventing the Peel
You’re probably going to peel. It’s your body’s way of getting rid of cells that are too damaged to function safely. But you can minimize the "lizard look" by moisturizing aggressively three to four times a day.
Avoid "anti-aging" products for at least two weeks. No retinol, no glycolic acid, no vitamin C serums. These are all actives that increase cell turnover or exfoliate, and your skin is already doing that at a traumatic pace. Stick to the basics: cleanse with a soap-free, fragrance-free wash, and moisturize with heavy creams.
Immediate Action Steps
- Cool down immediately: 15-minute cool shower or bath.
- Medicate early: Take an NSAID like Ibuprofen or Naproxen (Advil or Aleve) to reduce internal inflammation. This is more effective than any topical cream for the deep-tissue ache.
- Apply 1% Hydrocortisone: Target the reddest areas to stop the swelling.
- Seal it in: Use a fragrance-free, ceramide-rich moisturizer while the skin is still damp.
- Hydrate: Drink 16–20 ounces of water with electrolytes immediately.
- Assess: If you have a fever over 101°F or widespread blistering, call a doctor.
- Protect: Stay out of direct sunlight for 48 hours to prevent "compounding" the burn.
