I would advise against starting so close to your event. Here is the timeline: Session 1 happens today. For 24-48 hours, you will have redness and maybe some swelling around the follicles (it looks like goosebumps). That fades. Then, 10 to 14 days after the session, the dead hairs start pushing out of the skin. It looks like stubble or black dots. If you shave, they are still visible under the skin. For the bikini line, this 'shedding' phase is not cute. You want to start laser when you don't have a beach vacation for at least 6-8 weeks. For now, just wax for the event. Start laser the day you get back.
