Unlike traditional methods (waxing, shaving, bleaching, or using depilatory creams), DiolazeXL laser hair removal impacts the root of the problem, rather than offering a temporary solution. Traditional methods will require treatment forever, while DiolazeXL only requires a few sessions.During laser treatment, a diode laser beam passes through the skin towards hair follicles. The penetrating energy then heats up the root of the hair, which in turn prevents future hair growth.
