Healing Sunburn Blisters: Care Tips and When to See a Doctor

Sun blisters indicate second‑degree burns. Proper care prevents infection and scarring.

Do’s and Don’ts

• Don’t pop or peel—increases infection/scarring risk.
• Clean gently with mild soap/water; pat dry.
• Apply antibiotic ointment (e.g., bacitracin) thinly.
• Cover with non‑stick bandage or sterile gauze.
• Avoid sun exposure until fully healed.
• OTC pain relievers (ibuprofen/acetaminophen) for discomfort.
• Aloe vera gel soothes and supports healing.

See a Doctor If

• Blister is large, very painful, or on face/genitals.
• Signs of infection: increasing redness, swelling, pus, red streaks.
• No improvement in a few days.
• Fever develops.
