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.

  • 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.
