Thanks for your question and concern about treating herpes. As you know, photo epilation treatment is done to remove unwanted hair in body. It is done by passing intense light to hair follicles It is usually contraindicated in chronic and active herpes too. So, pre treatment of it, with anti-retroviral medications should be done a day before doing photo epilation and can be continued for about six or seven days. Hope that I have cleared your doubt. Take care.
