GentleLase laser hair removal uses a low-energy laser to gently remove unwanted hair. The laser energy passes through the skin and is absorbed by the pigment in the hair follicle. In a fraction of a second, all of the treated hair follicles are disabled. Patients should avoid tweezing, plucking or waxing 4-6 weeks prior to appointment. It is advised to shave hairier areas 1 day prior and/or use depilatories 3-5 days prior to treatment.
