long pulsed nd:yag laser hair removal

In long-pulsed mode (meaning the amount of time targeted tissue is exposed to laser energy), Nd:YAG lasers are widely used for hair removal in patients with dark skin, particularly those whose hair is …  RR Permanent hair removal by normal-mode ruby laser. Previous reports of long-pulsed Nd:YAG laser treatment in patients with dark skin phototypes have been limited by their short postoperative evaluations and/or limited treatment sessions but have substantiated its use in these individuals, nonetheless.17,18 Not surprisingly, the longer-pulse (millisecond) Nd:YAG system has been shown to be more effective in safely removing hair than has the Q-switched (nanosecond) Nd:YAG system, given its closer approximation to the target hair follicle's thermal relaxation time.19 It is likely that with equivalent fluences, shorter-pulse red and infrared laser systems can also permanently destroy hair follicles, albeit at the expense of the epidermis.  TS Long-pulsed alexandrite laser-assisted hair removal: comparisons at 5, 10, and 20 millisecond pulse durations. 2020 Mar;35(2):373-378. doi: 10.1007/s10103-019-02829-x.  DASiegfried  JA New concepts in therapeutic photomedicine: photochemistry, optical targeting and the therapeutic window. 404.

Treatment parameters for Wart using long pulse Nd YAG laser . Axillary hair was substantially more responsive to laser irradiation than was hair located on the legs and face. Results  Prolonged hair loss was observed 12 months after the final laser treatment (70%-90% hair reduction). The use of lasers with longer pulse durations (≤200 milliseconds) permit safe application of higher fluences to patients with darker skin tones, effectively heating the inner and outer root sheaths and the germinative zone without disrupting epidermal melanosomes (which typically respond to short [1-millisecond] pulses).20 Selective bulb and stem cell damage can thus be achieved with pulse durations much greater than the relaxation times of follicles (10-100 milliseconds).  MFarinelli  CMCole The Nd:YAG laser is the most common laser used in laser designators and laser rangefinders.. Nd:YAG laser is generally ineffective for light-coloured (blonde/grey) hair, but effective for treating dark (brown/black) hair in patients of Fitzpatrick types I to III, and perhaps light-coloured type IV skin. Subjective patient reports and adverse effects were also recorded at each follow-up visit. Depending on the pulse duration and energy density, this may result in the coagulation or blasting of these structures. Histological evaluations were performed by a board-certified dermatopathologist unaware of the study protocol (C.M.W.). Objective  In addition, the use of a long-pulsed Nd:YAG laser at high fluences can effectively treat patients with darker skin tones while producing few adverse posttreatment sequelae.  FDovale A dermatopathologist reviewed unmarked histological specimens obtained at baseline, immediately after the initial laser treatment, and at 1 and 6 months after the final laser session.  CJGlaser Private practice, ambulatory care facility.
