There may be some faint scars left by the stitching of beauty needles. Scar tissue is an inevitable product of human wound repair. Broadly speaking, there is no wound healing without scar tissue. All wounds are handled correctly, and slight scars may also occur. Cosmetic suture is an effective suture method to minimize scar, because the needle and thread of cosmetic suture are all non-invasive suture, and there will be no traces of "centipede foot" after suture removal, which will generally leave tiny or even linear traces. At present, it is suggested to use special anti-scar drugs for half a year after stitches are removed, which can improve the appearance of scars. In the later stage, laser and other treatment measures can be used to remove the scars formed after trauma to the maximum extent.
