Scarring is a somatic skin condition that often occurs in traumatic injuries such as ear piercings, or in small, unnoticeable injuries such as the chest where red bumps proliferate, making it unsightly and painful. This skin condition is somewhat genetic, i.e., scarring, so these patients should remember not to easily operate on their skin or to scratch or squeeze the skin “sores” with their hands. The treatment of huge scars, such as a large piece hanging from the ear, is very uncomfortable and should not be treated by surgical removal alone, otherwise it will grow even larger than before the removal, and should be treated by a comprehensive treatment of scars in the dermatology department, which can keep 80% of patients from recurring after treatment, and a few recurring patients can be controlled from growing up by coming back for treatment at the early stage of recurrence.
