Our providers at Dash Medical Spa advise that you stop waxing, tweezing, or plucking hair you want to remove for two to six weeks before your appointment, though shaving is fine. You should also avoid UV exposure during the month before your treatment, including that from tanning beds and self-tanning lotions. Within 48 hours of your appointment, shave the area that’s being lasered using a clean, new blade. This helps the laser light locate your hair follicles.
