The DiolazeXL has built-in safeguards to ensure that all sessions are comfortable and relatively pain-free. Our nm (nanometre) wavelength depth can target anagen hairs accurately which provides fast and effective results, by killing/destroying the follicle on impact. The DiolazeXL makes use of Triton Duo Multi-Wavelength Technology, which allows for the treatment of deep and superficial hairs at the same time. So, fewer treatments are required. Treated areas should be shaved, preferably 2-3 daysprior to treatment
