Hi, Medicines have a very limited effect on scars. You will need a surgical procedure to make the scar look better or go away entirely. Scars are of many different types and accordingly, the procedures to make them better are also of many different types. These procedures are painless as they are done under local or general anesthesia. Visit a plastic surgeon to discuss all options for your particular case. The cost will also vary according to which procedure is needed. Take care, Dr Siddharth Prakash
