The main reason for vaginal dryness is the decrease of vaginal secretions, insufficient moistening of the internal environment, and painful intercourse. The solutions for vaginal dryness and pain are: 1) use lubricating fluid to improve the moistening of the vagina and reduce the pain; 2) go to the plastic surgery department of a regular hospital for laser treatment, which can fundamentally solve the problem of insufficient vaginal secretions and dysfunction of the secretory glands. Laser treatment can restore the function of the secretory glands and make them secrete more secretions, so that the problem of vaginal dryness and painful intercourse caused by insufficient vaginal wetness can be solved.
