Herpes lesions usually heal without scarring, but if scarring occurs, it is usually caused by infection or other conditions during the healing process. Once a scar appears, it will not go away. The scar will proliferate for about 3-6 months, and will gradually fade after the proliferation period when the local area is red due to the proliferation and expansion of capillaries.
Red scar after herpes is mostly caused by infection during the healing process. Scars left after herpes are generally more difficult to fade naturally, and can be lightened by laser and other methods. On the other hand, red marks that appear during the proliferative period of herpes scarring can usually fade away at the end of the proliferative period of scarring, i.e. after 3-6 months.
Good wound care should be taken during the herpes healing period to avoid infection, prevent scar proliferation and reduce the chances of red marks appearing on the scar. If herpes wound infection occurs during the healing period, you can go to the dermatology department of a regular hospital in a timely manner to identify the cause of the infection and carry out targeted treatment as soon as possible.
