Your vagina changes with childbirth and age. Vaginal rejuvenation or Vaginoplasty refers to anything that changes your vagina, externally and internally.
It involves tightening the inner-outer muscles and vaginal structures to enhance vaginal muscle tone, control, and strength. Note that women undergo this surgery for purely cosmetic reasons.
So decide if this procedure is required for you. Each woman’s body is different. Hence even before you decide anything, talk with your gynaecologist. That is the best way forward.
