The main purpose of vaginal rejuvenation is to change the laxity of a woman’s vagina. It is usually used for middle-aged and older women with vaginal laxity, women with a history of childbirth or vaginal lateralization, and women with congenital vaginal laxity. 1. Middle-aged and older women. As we age, the ovarian function gradually declines and the estrogen level decreases, causing degenerative lesions in the vaginal muscle layer, resulting in vaginal laxity. Vaginal rejuvenation can effectively improve vaginal laxity in this group. 2. Women with congenital vaginal laxity. This can also be improved by vaginal rejuvenation if the vagina is still lax even though there was no vaginal delivery. 3. Women who have a history of childbirth or vaginal scoliosis. Vaginal rejuvenation can be used to treat women who have had a vaginal birth, perineal tear or vaginal scoliosis, and to remedy vaginal laxity due to vaginal trauma. Vaginal rejuvenation is widely used in clinical practice, with mature technology and minimal side effects, and is suitable for improving vaginal laxity in women.
