Women can use lotion to wash their vulva during their menstrual period. It is easy for bacteria to grow during menstruation, so using a lotion to wash the vulva can inhibit the growth of bacteria, keep it clean and hygienic, and improve the symptoms of vulvar itching and discomfort. However, you must pay attention to the method of use during the cleaning process and do not wash the vagina. During menstruation, the endocervix is open and the immunity of the body is relatively low, so if you rinse the vagina with lotion, the vaginal acidity will be destroyed if you use it improperly, and the sewage entering the uterine cavity will cause inflammation in the uterine cavity, leading to endometritis and pelvic inflammatory disease. Therefore, during menstruation, care should be taken not to let the washing solution enter the vagina to avoid stimulation of the vagina. It is not recommended to use lotion to clean the vulva for a long time, as it may lead to dysbiosis. In addition, during menstruation, you should pay attention to keep your perineum clean and change your sanitary napkins regularly to avoid infection. After washing your underwear, you can expose it to the sun to achieve the purpose of sterilization.
