Despite your best sunscreen efforts, it happened — your child’s nose is pink, their shoulders are warm, and they’re complaining it hurts. Sunburn in kids is common, and while prevention is always best, knowing how to treat it safely brings fast relief.
Children’s skin is thinner and more sensitive than adults’, so sunburn can develop faster and feel worse. Here’s your complete guide to soothing sunburn safely, recognizing warning signs, and preventing the next one.
How to Tell If It’s Sunburn
Sunburn symptoms usually appear 2–6 hours after sun exposure and peak at 12–24 hours:
- Red, warm skin (most common on nose, cheeks, shoulders, back)
- Tenderness or pain when touched
- Mild swelling
- In worse cases: blisters, headache, or chills
If the burn covers a large area, blisters extensively, or your child has fever, vomiting, or dizziness — seek medical care promptly.
Immediate Steps for Sunburn Relief
1. Get Out of the Sun
Move indoors or to full shade immediately. Further exposure worsens the burn, even through cloud cover.
2. Cool the Skin Gently
- Apply cool (not ice-cold) damp cloths for 10–15 minutes
- Let your child take a cool bath or shower
- Avoid ice directly on skin — it can damage already-injured tissue
3. Moisturize While Damp
After cooling, pat skin dry gently (don’t rub) and apply a fragrance-free moisturizer or pure aloe vera gel. Moisturizing while skin is slightly damp locks in hydration.
Best options:
- Pure aloe vera gel (check it’s fragrance-free)
- Fragrance-free moisturizing cream
- Avoid products with alcohol, which sting and dry
4. Keep Them Hydrated
Sunburn draws fluid to the skin’s surface, which can dehydrate. Offer plenty of water — more than usual.
5. Dress in Loose Clothing
Tight clothes rub and irritate burned skin. Choose soft, loose cotton that lets skin breathe.
What About Pain Relief?
For discomfort that interferes with sleep or daily activities:
- Children’s ibuprofen or acetaminophen can help (follow package dosing by weight/age)
- Never give aspirin to children
- If you’re unsure about medication, call your pediatrician
Don’t Pop Blisters
If blisters form, leave them alone. Blisters protect the healing skin underneath. If one breaks on its own:
- Gently clean with mild soap and water
- Apply antibiotic ointment
- Cover loosely with a bandage
- Watch for signs of infection (increasing redness, pus, warmth)
How Long Does Kids’ Sunburn Last?
- Mild sunburn: 3–5 days (redness fades, possible light peeling)
- Moderate sunburn: Up to a week
- Peeling: Normal as skin heals — don’t pick at it; moisturize instead
When to Call the Doctor
Seek medical care if your child has:
- Blistering over a large area
- Fever above 100.4°F (38°C) with sunburn
- Severe pain not relieved by children’s pain reliever
- Signs of heat exhaustion: dizziness, nausea, rapid pulse, confusion
- Signs of infection in blistered areas
For babies under 6 months with any sunburn, call your pediatrician — their skin is especially vulnerable.
Preventing the Next Sunburn
- Apply broad-spectrum SPF 30+ sunscreen 15 minutes before going out
- Reapply every 2 hours (and after swimming/sweating)
- Seek shade between 10 AM and 4 PM
- Dress kids in UV-protective clothing and wide-brimmed hats
- Don’t forget ears, feet, and the back of the neck
The Bottom Line
Sunburn happens to the best-prepared parents. Cool the skin, moisturize gently, keep your child hydrated, and watch for warning signs. Most mild sunburns heal within a week with simple home care.
