First of all

Scars will not be completely removed, but they can be made less obvious through treatment. Scar treatments can only reduce or change the size or shape of scars.

The plans vary depending on the specific shape of the scar.

The methods for treating scars include:

Microcrystalline grinding, surgical excision, and skin grafting (posterior skin grafting) darker than the skin), the dilator is embedded. You still need to choose a treatment plan based on your own situation and the size and depth of the scar.
