Sunburn Relief: Evidence-Based Treatment and Healing Strategies

Sunburn is radiation injury to skin from UV exposure. Treatment focuses on cooling, hydration, inflammation reduction, and barrier support while skin regenerates.

Immediate Actions (First 24-48 Hours)

1. Cool the skin: Cool (not ice-cold) baths/showers or compresses 10-15 minutes, several times daily. Avoid direct ice—causes vasoconstriction and further damage.
2. Hydrate aggressively: Sunburn draws fluid to skin surface. Drink water, electrolyte solutions. Monitor urine color.
3. Moisturize damp skin: Apply fragrance-free, alcohol-free moisturizer (ceramide-containing ideal) within 3 minutes of bathing. Avoid petroleum jelly, oils, butter—they trap heat.
4. NSAIDs: Ibuprofen 400-600mg every 6 hours with food reduces inflammation, pain, and erythema if started early.

Topical Therapies

• Aloe vera gel (pure, 90%+): Anti-inflammatory, wound-healing polysaccharides. Refrigerate for added cooling.
• Hydrocortisone 1% cream: For significant inflammation/itching; thin layer 2-3x daily (max 1 week).
• Colloidal oatmeal baths: Soothes itching, restores barrier.

Blister Management

• Intact blisters: Leave alone—sterile biological dressing. Cover loosely with non-adherent gauze.
• Ruptured blisters: Gentle cleansing, antibiotic ointment (bacitracin), non-stick dressing.

Red Flags—Seek Medical Care

• Blistering >20% body surface area (entire back, both legs, etc.)
• Fever >101°F (38.3°C), chills, confusion
• Signs of infection: increasing pain, pus, red streaks
• Severe dehydration (no urine 8+ hours, dizziness)
• Sunburn in infant <1 year

Prevention: The Best Treatment

Broad-spectrum SPF 30+, reapplied every 2 hours; UPF clothing; shade 10 AM-4 PM; sunglasses. Cumulative UV damage increases skin cancer risk regardless of burn history.
