There are many methods to treat postpartum stretch marks in clinic. First of all, in terms of external drugs, for traces of early pregnancy, tretinoin drugs can be selected for external use, such as tretinoin cream and tazarotene gel. And we can also choose asiaticoside cream and vitamin E cream for external use. Because its formation mechanism is similar to scar, we can also use external drugs to inhibit scar formation, such as polysulfonate mucopolysaccharide cream. Secondly, in terms of physical therapy, we can choose microcrystalline dermabrasion to remove surface cells by mechanical force, thus improving stretch marks, or we can choose lattice carbon dioxide laser therapy to induce dermal collagen fiber proliferation through the photothermal effect of lesions, which is beneficial to the repair of stretch marks. You can also choose radio frequency therapy to generate a lot of heat energy by emitting electromagnetic waves, so that dermal collagen fibers can be remolded and regenerated, thus restoring the appearance of tissues.
