V-Lase is a harmless, non-ablative strategy that utilizations controlled laser warming to invigorate the development of collagen and a fresh blood supply to further develop thickness and flexibility to the vaginal wall. The created laser bar is produced in a beat design that doesn't make harm the shallow vaginal wall.

V-Lase is a painless, non-ablative technique that utilizations controlled laser warming to invigorate the development of collagen and a fresh blood supply to further develop thickness and flexibility to the vaginal wall. The produced laser shaft is radiated in a beat design that doesn't make harm the shallow vaginal wall. This laser bar attempts to advance the development of elastin filaments and collagen in the profound layers of the vaginal wall. Thus, the treatment gives alleviation from agonizing intercourse because of vaginal dryness.
