Typical symptoms of keloid are skin injuries caused by trauma, burns, acne, insect bites, etc., which cause keloid scars on the patient’s body surface. After the wound heals, the keloid scar grows outward, protrudes on the surface of the skin, is hard, exceeds the scope of the original injury, does not subside on its own, and expands to the surrounding normal skin infiltration. The skin lesions can be red at the beginning, and then gradually become brown. Accompanying symptoms of most patients with keloid, the affected area is over-sensitive, easy to itch, sometimes pressure on the affected area will cause pain. In some cases, the scarring area may be hypersensitive, itchy and sometimes painful when pressed.

It is recommended that patients with these symptoms go to the dermatology department of a regular hospital.
