The characteristics of a<unk>  depend upon its depth. Superficial<unk> s cause pain lasting two or three days, followed by peeling of the skin over the next few days. Individuals suffering from more severe<unk> s may indicate discomfort or complain of feeling pressure rather than pain. Full-thickness<unk> s may be entirely insensitive to light touch or puncture. While superficial<unk> s are typically red in color, severe<unk> s may be pink, white or black.<unk> s around the mouth or singed hair inside the nose may indicate that<unk> s to the airways have occurred, but these findings are not definitive. More worrisome signs include: shortness of breath, hoarseness, and stridor or wheezing. Itchiness is common during the healing process, occurring in up to 90% of adults and nearly all children. Numbness or tingling may persist for a prolonged period of time after an electrical injury.<unk> s may also produce emotional and psychological distress. Type Layers involved Appearance Texture Sensation Healing Time Prognosis and Complications Example Superficial (first-degree) Epidermis Red without blisters Dry Painful 5–10 days Heals well. Repeated sunburns increase the risk of skin cancer later in life. A sunburn is a typical first-degree<unk> . Superficial partial thickness (second-degree) Extends into superficial (papillary) dermis Redness with clear blister. Blanches with pressure. Moist Very painful 2–3 weeks Local infection (cellulitis) but no scarring typically Second-degree<unk>  of the thumb Deep partial thickness (second-degree) Extends into deep (reticular) dermis Yellow or white. Less blanching. May be blistering. Fairly dry Pressure and discomfort 3–8 weeks Scarring, contractures (may require excision and skin grafting) Second-degree<unk>  caused by contact with boiling water Full thickness (third-degree) Extends through entire dermis Stiff and white/brown. No blanching. Leathery Painless Prolonged (months) and incomplete Scarring, contractures, amputation (early excision recommended) Eight day old third-degree<unk>  caused by motorcycle muffler. Fourth-degree Extends through entire skin, and into underlying fat, muscle and bone Black; charred with eschar Dry Painless Does not heal; Requires excision Amputation, significant functional impairment and in some cases, death. 4th-degree electrical<unk>
