Postpartum stretch marks generally do not disappear, mainly due to the tension during pregnancy, resulting in the degeneration and breakage of collagen and elastic fibers under the abdomen, so the formation of stretch marks. Once formed, stretch marks are difficult to fade on their own, sometimes even after treatment, the color will only fade at most, and may generally exist for life. Of course, if the stretch marks are obvious, you can try to lighten them through physical means after giving birth, or use drugs to promote the absorption of local inflammation, which can also try to lighten the appearance of stretch marks.
