Indications and non-indications for laser treatment of vaginal laxity: Indications: people with symptoms of aging of the perineum such as vaginal laxity, vaginal dryness and pigmentation. Non-indications: Pregnant women, those with gynecological inflammation and those who cannot tolerate the procedure. Laser treatment for vaginal laxity is also based on the principle of selective photothermolysis. The laser acts on the vaginal mucosa, stimulating collagen fiber proliferation, remodeling damaged collagen and elastic fibers, increasing the thickness of the vaginal wall and tightening the vagina. The laser can enhance vaginal mucous membrane secretion, improve vaginal lubrication and sensitivity, promote the normalization of vaginal pH and flora, and stabilize the vaginal environment. Laser treatment for vaginal laxity is painless: the laser probe is only inserted into the vagina for irradiation, which is painless and does not require anesthesia. The penetration depth of the laser is limited, so the treatment of vaginal laxity only causes slight reversible damage to the vaginal mucosa and does not negatively affect the cervix, urethra or rectum, and does not affect normal fertility; the laser is not a radiation and will not cause radiation damage to the body. Laser treatment for vaginal laxity is a course of treatment for 3 times in a row, with one month interval between each laser treatment. Laser treatment for vaginal laxity only takes 15 minutes and can be done as you go, without hospitalization or vacation, and you can work normally. Complications of laser treatment for vaginal laxity: scar formation is possible after any laser treatment, but it has not been reported yet.
