This is a very headache. There are several aspects to removing scars. First, you can make lasers, such as carbon dioxide lattice lasers or plasma lasers. These lasers can stimulate the proliferation and remodeling of elastin and collagen in scars, make the color and texture of scars closer to the surrounding normal skin, and can dilute scars. It usually takes 3-5 times for laser to improve scars, and the interval between each time is about three months, which can achieve ideal results. Secondly, if the scar is too large or too wide and some areas are sunken, surgery is needed. Generally, if it is a linear concave scar, it can be removed and sutured again, which can achieve beautiful results. Laser therapy can be performed again after stitches are removed, which is beneficial to the recovery of scars. In addition, if it is a large area of flaky scar, it is necessary to do dilator surgery. This operation is carried out according to the course of treatment, and a course of treatment takes about three months, which is a relatively large operation. Generally speaking, scar treatment depends on the area, location and depth of the previous scar. Different scars have different treatments. You can go to the plastic surgery department for medical treatment, and the doctor will give you a suitable treatment plan.
