Symptoms of being burned by fire

Erythematous burns only damage a part of the epidermis, but the germinal layer is still alive, so the proliferation and regeneration ability is active. They usually heal within 3-5 days without leaving scars. The whole epidermis and part of the papillary layer were injured. As the germinal layer is partially damaged, epithelial regeneration depends on the epithelial proliferation of the remaining germinal layer and skin appendages, such as sweat glands and hair follicles. If there is no secondary infection, it is usually healed after 1-2 weeks, and no scar is left.

The healing depends on the proliferation of epidermal progenitor cells in the epithelium of skin appendages, especially in the hair follicle protrusion. If there is no infection, it usually needs 3-4 weeks to heal, often leaving scars. There are many clinical variations, the shallow is close to the shallow grade II, and the deep is critical grade III.
