It is not recommended to use alcohol to disinfect the vulva. The skin of the female vulva is delicate and alcohol is dry with volatile effects. If alcohol is used for disinfection, it can easily lead to dry and uncomfortable skin on the vulva. If the vulva needs to be disinfected for examination, complex iodine is usually required. If the vulva is uncomfortable, such as vulvar itching, leucorrhea, vaginal odor, etc., you can use external lotions, such as Baiyai lotion, red nucleus lotion, gynecological lotion, etc., as appropriate. These lotions need to be diluted before use, not directly applied to the vulva. You should also pay attention to the hygiene of your vulva and wear less tight underwear.
