In cases of trauma or injury, it is very easy to develop hypertrophic scars. Generally, the size and depth of the wound are related factors. Scars often present with symptoms like redness, itching, and raised hard areas. There are mainly two approaches to treat this type of scar. The first method involves improvement through medications, using topical drugs or local injections to help eliminate hypertrophic scars. The second method involves surgical approaches, such as laser surgery, which is a common method of repair. Generally, local burning from the procedure can achieve certain effects. Of course, after using laser surgery, a specific recovery period is required. During this period, it is necessary to avoid infections to aid in the repair of hypertrophic scars.
