First Degree Burns CHARACTERISTICS• Abnormal redness of the skin • Involves only the epidermis (first layer of

skin) • No blistering • Mild total body effects • Heals in 3 to 4 days

Second Degree Burns Superficial Partial Thickness

CHARACTERISTICS• Papillary dermis (upper portion of the

second layer of skin) – Affects the first layer of skin and the top

of the second layer of skin • Blister formation • Burn appears pink and moist • Painful, very sensitive • Turns white to the touch • Hair usually intact • Doesn’t scar–change in skin color

Second Degree Burns Deep Partial Thickness

CHARACTERISTICS• Reticular dermis (lower portion of second

layer of skin) – Involving tissue layers underneath

top skin layers• Healing process more than 3 weeks • Spotted red and white • Decreased pain • Doesn’t turn white to the touch • Hairs pluck out easily • Scarring increases • May require surgical cleaning or grafting

Third & Fourth Degree Burns Full Thickness

CHARACTERISTICS• Burn is into fat or deeper • Area is red, white, brown or black • Not painful • Area is dry or leathery • Doesn’t turn white to the touch • Heals only from the edges • Almost always requires surgery
