Scar after trauma usually takes 3-6 months to operate, so please come to the clinic. At present, only some drugs can be used externally.

Wang Xi, a doctor from Shanghai Ninth People's Hospital, solemnly reminds me that I can't fully understand my illness because I can't meet the patient face to face. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
