Laser hair removal is a very effective way to permanently remove hair. Although certain areas (such as the bikini area, under the arms and the upper lip) are more sensitive than others, as a result of the a new generation of prescription strength topical anesthetics, it need not be a painful procedure. Here’s how to get the most benefit from them:
Apply the topical anesthetic to freshly cleansed and dried skin 45 minutes to an hour before your procedure.
Rub in that first layer vigorously for 15 to 30 seconds.
Next apply a second thicker layer on top of the first one.
Third, put clear plastic food wrap over the area to maximize the penetration of the anesthetic.
Leave the wrap on the area until you start your treatment.
