Does it matter in which day of my period I will have laser hair removal for vagina?

It will be wiser to do your laser hair removal treatment after you are done with your cycle. Women are relatively more sensitive to pain around that time of the month.

Scientifically speaking, it shouldn’t. Laser does not penetrate further than the dermis of your skin, where it disperses the hair follicle. I would recommend you to make an appointment with your OB/GYN to tackle this issue.

It is preferable that you wait until your cycle has stopped before you treat with laser hair. Not only for the practitioner providing the service but also for you. Women tend to be more sensitive that time of the month, making it much more painful.
