Cool the skin with cool water and apply an alcohol-free aloe or soy moisturizer while it’s still damp for the fastest relief, then take an over-the-counter pain reliever and drink extra water.
That first hour sets the tone for the next three days. Sunburn is a real burn — UV radiation damages skin cells, and the redness and swelling is your body’s inflammatory response.
What Should You Do First When You Realize You’re Burned?
Get out of the sun and cool the skin with cool — not cold — water. The American Academy of Dermatology (AAD) puts sun avoidance first, since continued exposure compounds the damage.
Take frequent cool baths or showers and pat dry gently. Mayo Clinic suggests soaking a clean towel in cool tap water and draping it over burned areas.
Skip the ice pack. Mayo Clinic warns against ice or very cold water — extreme cold can damage compromised skin and doesn’t cool faster than plain cool water.
What to Put on Sunburned Skin
Apply an alcohol-free moisturizer with aloe vera or soy while skin is still damp, then reapply as discomfort returns — the damp-skin timing locks moisture in before it evaporates.
Mayo Clinic recommends aloe products or calamine lotion and notes that chilling the product can improve comfort. Alcohol-based gels and lotions sting and dry out burned skin, so leave those on the shelf. For a shortcut past drugstore guesswork, this roundup of the best after sunburn lotion options covers texture, absorption, and which formulas skip alcohol.
Follow the label and check with a pharmacist or clinician first — especially for children, facial skin, broken skin, or large areas.
The AAD also lists colloidal oatmeal baths and cool, damp cloths as soothing options. More detail appears in the AAD’s sunburn treatment guidance.
How Do You Manage the Pain and Swelling?
An over-the-counter pain reliever handles the ache, and drinking extra water for about a day offsets dehydration. The AAD lists aspirin or ibuprofen; Mayo Clinic lists ibuprofen and acetaminophen.
There’s no universal dose to quote. Aspirin and ibuprofen aren’t suitable for everyone — stomach issues, blood thinners, pregnancy, and kidney problems all change the math — and acetaminophen carries labeled maximums and liver warnings. Use only what the label and your clinician allow.
Leave intact blisters alone — they’re a sterile bandage, and popping one invites infection. The AAD recommends keeping them clean and applying petroleum jelly while they heal. If a blister breaks, Mayo Clinic advises gentle cleaning with mild soap and water, trimming only dead skin with small clean scissors, antibiotic ointment, and a nonstick bandage.
| Remedy | How to Use It | Watch Out For |
|---|---|---|
| Cool bath or compress | 10 minutes, several times daily; pat dry | No ice or very cold water |
| Aloe or soy moisturizer | Apply to damp skin; reapply as needed | Alcohol-based formulas |
| 1% hydrocortisone cream | Three times daily for three days | Check with a clinician first |
| Calamine lotion | Apply to affected areas; chilling helps | Skip on broken skin |
| Colloidal oatmeal bath | Soak as directed on the package | Pat dry, don’t rub |
| Ibuprofen or acetaminophen | Per the label only | Contraindications and interactions |
| Petroleum jelly | On clean, intact blisters | Never pop blisters |
When Does Sunburn Need a Doctor?
Large blisters, blisters on the face, hands, or genitals, signs of infection, deep or extensive burns, or systemic symptoms like fever and chills call for medical evaluation instead of home treatment. While skin heals, keep the area covered and out of direct sun — Mayo Clinic notes avoiding exposure matters until the burn fades. Loose clothing beats tight straps, and most sunburns peak in discomfort during the first 24 hours, then slowly fade.
Common Questions
Should you moisturize a sunburn or let it dry out?
Moisturize it. Dry, tight skin cracks and itches more, and the AAD recommends applying an aloe vera or soy moisturizer while skin is still damp after a cool bath or shower. Reapply whenever discomfort returns, and choose an alcohol-free formula.
Can you put ice directly on sunburned skin?
No. Mayo Clinic advises cool — not cold — water and warns against ice, which can further damage injured skin. A cool bath, cool damp towel, or compress held for about 10 minutes is safer and can be repeated several times a day.
How long does sunburn take to fade?
Mild burns often peak in discomfort during the first 24 hours, then gradually improve. Blisters take longer and should be left intact.
