Stretch marks can be repaired by laser treatment, microcrystalline skin resurfacing, radio frequency technology and other medical aesthetic techniques. 1. Laser treatment: it uses the selective photothermal effect of laser to stimulate the regeneration and remodeling of collagen fibers and elastic fibers in the dermis layer, and multiple treatments can reduce or eliminate the effect of stretch marks. 2. Microdermabrasion: Using the principle of physical grinding, the epidermal horny layer is removed, so that the epidermal regeneration ability and skin texture can be improved to realize the effect of lightening stretch marks. 3. Radiofrequency technology: through the non-selective heating effect, so that the collagen fibers of the dermis layer of the skin by thermal denaturation, and then regeneration, remodeling, to achieve the effect of repairing stretch marks. After the birth of the belly stretch marks trouble, it is recommended to go to a regular professional hospital in time to understand the repair technology.
