Obesity lines cannot be eliminated, but they can be improved with treatments such as radiofrequency and fractional laser. Obesity lines are caused by short-term weight gain, the subcutaneous tissue grows faster than the skin, resulting in a break in the subcutaneous dermis. Dermal breaks can not be completely repaired, the appearance of obesity lines can be improved by photoelectric treatment. 1. Bipolar radio frequency: radio frequency is the principle of electromagnetic waves in the dermis, can let the local skin produce a lot of heat, so that the collagen fibers and elastic fibers structure changes, the organization of the arrangement is more dense, so as to improve the obesity lines. 2. Fractional laser: its main role in the target tissue containing water, the laser is absorbed by the water-containing tissues, the local photothermal effect, the formation of dermal stimulation, can promote the generation of new collagen fibers and collagen regeneration and rearranging, so as to improve the obesity lines. In addition, it is recommended that patients who are willing to treat obesity lines should go to regular medical institutions and be treated under the correct operation of doctors.
