Table 1. Table depicting different types of burn with details^18-21 .

Type	Layers involved	Appearance	Texture	Sensation	Healing Time	Prognosis	Example
Superficial (first-degree)	Epidermis	Red without blisters	Dry	Painful	5-10 day	Heals well. Repeated sun burns increase the risk of skin cancer later in life.
Superficial partial thickness (second-degree)	Extends into superficial (papillary) dermis	Redness with clear blister. Blanches with pressure	Moist	Very painful	2–3 week	Local infection (cellulitis) but no scarring typically
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)
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)
Fourth-degree	Extends through entire skin, and into underlying fat, muscle and bone	Black; charred with a scar	Dry	Painless	Requires excision	Amputation, significant functional impairment and in some cases, death.
