Obesity lines, i.e. atrophy lines or expansion lines, are mainly caused by the degeneration and brittleness of skin elastic fibers, which are subjected to excessive pulling and thus breakage. Fractional laser, bipolar radio frequency and other methods can be chosen to eliminate. Obesity line is a kind of stripe caused by excessive obesity, at present there is no effective oral or external drug, fractional laser is one of the methods to remove it. Through fractional laser action on obesity lines, the local production of photothermal effect, the formation of stimulation of the dermis, and then promote new collagen fibers and collagen remodeling, in order to achieve the improvement of the role. Bipolar radio frequency is also a method of removing obesity lines, can make the collagen fibers and elastic fibers structure change, the tissue arrangement is more dense, so as to improve the obesity lines. The removal of obesity lines need to go to a regular hospital, under the operation of medical professionals.
