In one pulse, the laser can remove all the hair on a patch of skin the size of a nickel (depending on the specific laser spot size, i.e. the “laser head,” ranging from 9-18mm on average). Everyone’s pain threshold is different and generally laser hair removal is not much more painful than waxing, but the sensation is different. It resembles a rubber band snapping against the skin for a quick second with each pulse. Most people do not require an anesthetic cream (like EMLA), but one may be used for very sensitive patients/areas (can be provided or prescribed at the clinic). However, if you do not feel any pain at all, it might be an indication that the settings are set too low to actually kill the hair. Please advise your clinic if this is the case.
Be aware that using anesthetic creams is only safe on small areas (like upper lip, bikini, or underarms) and in small quantities. Using it on large areas in high lidocaine doses, for example on an entire back, can cause adverse effects or even death. Consult with your clinic and doctor if unsure.
