Chickenpox does not usually leave a scar when it breaks, but it depends on the individual. Chickenpox is a skin disease caused by the varicella-zoster virus infection, and the main symptoms include fever, blisters all over the body, and some degree of itching. The varicella-zoster virus usually just invades the epidermal cells of the skin, causing localized lesions in the epidermis, resulting in blisters. The damaged area is usually shallow, so even if there are erosions and ulcers, if there is no mechanical damage such as local soft tissue infection or scratching during the recovery process, basically no scar will be left. However, if you do not take good care of the chickenpox erosion and ulceration, resulting in local bacterial infection, you may damage the dermis or even subcutaneous tissue, which may leave scars. After the chickenpox should be actively to the regular hospital, follow the doctor’s advice to use standardized treatment program, usually also need to do a good job of care, to avoid infection, so as not to leave scars.
