Burn Depth Classification: Superficial vs Partial Thickness vs Full Thickness — Appearance, Pain, Healing
A burn patient screaming in pain likely has a more survivable injury than the one who feels nothing. Full-thickness burns destroy nerve endings — painless and leathery — yet they're the ones requiring surgical grafting. Mixing up depth means mistriaging who needs the OR and who needs wound care.

Skin layers involved
- Epidermis only; dermis intact
- Epidermis + upper dermis
- Epidermis + deep dermis
- Epidermis + entire dermis ± subcutaneous
Appearance / color
- Red, dry (classic sunburn)
- Pink-red, moist, glistening
- Mottled red/white, waxy areas
- ★White, waxy, leathery, or charred
Blisters
- None (epidermis intact)
- Fluid-filled blisters — hallmark
- May be ruptured; wound bed variable
- None — skin too destroyed
Pain level
- Mild pain (sunburn)
- ★MOST painful — exposed nerve endings
- Pressure sensation only; ↓ sharp pain
- ★Painless — nerve endings destroyed
Blanching with pressure
- Brisk capillary refill
- Blanches and refills
- Sluggish or absent blanching
- No blanching — thrombosed vessels
Healing / grafting
- Heals 3–5 days; no grafting
- Heals 1–3 weeks; no grafting
- Heals 3–8 weeks; may need graft
- Will not heal — needs excision + graft

Clinical Pearl
More pain means more superficial — painless, leathery, and white means full thickness and the OR.
