Tonight i burned my genital area with nair hair removal cream. how long will it take to heal and also when is it ok to have sex again?

Chemical burn: Nair should not be used any where near the mucosal tissue of the labia or vagina because (as you learned ) it can cause chemical burns. You should be examined to evaluate the extent of the damage and evaluate for signs of superimposed infection. Silvadene cream is a soothing medication that can be used in these circumstances. Avoid intercourse until healing is complete.
