Normally the vaginal tissue has a good elasticity. Due to aging and childbirth, the elasticity may become weakened and you may feel that you have a loosened vagina. This often occurs during or after menopause.
At 48, you can start with NeuEve Silver suppository (use it once every 5 days) plus vulva balm cream (use it once daily), your elasticity will grow back in a few months because these products deliver nutrients to promote growth of collagen and elastic fibers in the vaginal tissue.
Taking certain dietary dietary supplements can also help you find relief sooner.
Additionally, Kegel exercise may help you speed up the recovery. This link provides some good information about Kegel exercise for women:
