Scarring is possible with any wound healing, a compensatory repair acquired by humans in the course of nature. However, excessive hyperplasia can result in pain and itching, changes in appearance and even deformity and dysfunction. If the wound or wound heals for a long time, more than 14 days, you can use prophylactic silicone films and ointments, Conrad, cumene, etc. If the skin is red or rough after healing, then the best preventive method is pressure therapy. In short, it is a durable compression with elastic fabric. In any case, the first or second treatment should be properly guided by a doctor. As for scars that are more than 1 year old, that needs to be addressed by surgical treatment. Of course, if the scar is less than a year old and already deformed, then you still need to see a doctor and discuss early surgery with him/her.
