CLARITY is a dual wavelength platform that effectively delivers a variety of parameters and incredibly fast treatments.  M The relatively high concentration of melanin in hair follicles compared with the epidermis in these patients ensures a high level of efficacy and target-specific energy absorption when pigment-specific lasers are used. The clinical study concluded that “ The long-pulsed 1064-nm Nd:YAG laser is a safe and effective method of long-term hair reduction in patients with darkly pigmented skin.  CMCole With thick skin, it may become difficult to achieve adequate penetration of energy deep into the follicle. Olsen  MWFoster  EFSuthamjariya Zero indicates less than 25%; 1, 25% to 50%; 2, 51% to 75%; 3, 76% to 90%; and 4, greater than 90%. All Rights Reserved. Sun-protected and thinner axillary skin showed greater clinical response to and fewer adverse effects of laser treatment than did sun-exposed facial and leg skin. It does not have any health risks and major side effects. Nd: YAG laser energy is selectively absorbed by the deeper levels of the dermis and allows for treatment of deeper vascular lesions such as telangiectasias, hemangiomas, leg veins and hair removal. All patients were evaluated at least 3 months after the last treatment, and their present conditions were compared with the 1st-day photographs.  WFlotte Fifty women (skin phototypes IV–VI) volunteered for removal of axillary hair. 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). Photographs using identical lighting, patient positioning, and camera equipment were obtained of all treatment sites before each of the 3 treatment sessions and at 1, 3, 6, and 12 months after the final treatment. Evaluation of Laser Effects on the Human Body After Laser Therapy. Goldberg Three consecutive, long-pulsed (50-millisecond) 1064-nm Nd:YAG laser treatments were delivered on a monthly basis to the involved treatment areas by a single operator (T.S.A.). Comparative evaluation of long-pulse alexandrite and long-pulse Nd:YAG laser systems used individually and in combination for axillary hair removal. Although technological advances of laser-assisted hair removal during the past 5 years have been highly gratifying, the rapidity of development has not been entirely without drawbacks.

Laser Hair Removal Fotona's high-performance Nd:YAG laser systems with FRAC3® technology have introduced new standards of efficiency in providing safe and effective hair reduction – using an innovative system that effectively targets hair follicles with a combination of selective and homogenous photothermolysis. THE CLINICAL results achieved by laser hair-removal systems since 1995 constitute an impressive but essentially qualified success. Histological changes mirrored clinical response rates, with evidence of selective follicular injury without epidermal disruption. Axillary hair demonstrated the most impressive hair reduction scores, averaging 2.8 after 1 treatment, 3.6 after 2 treatments, and 4.0 at 1 and 3 months, 3.8 at 6 months, and 3.5 at 12 months after the third treatment (Figure 3). Substantial hair reduction was seen after each of the 3 treatment sessions. Fifty women (skin phototypes IV-VI) volunteered for removal of axillary hair. Commonly used to refine pores, rejuvenate skin, remove hair, and reduce the appearance of deep vascular lesions, the Long-Pulsed Nd:YAG Laser is a safe and effective treatment that utilises a near-infrared wavelength to penetrate deep into the skin.  MSlatkine It is mostly used for the patients with darkly pigmented skin. Results  Twenty women with skin phototypes IV through VI and dark brown to black terminal hair on the face, axillae, or legs. In recent years, various light sources (lasers and others) have been developed for long-term epilation of unwanted hair. Immediately before each treatment, hairs longer than 1 mm were shaved close to the skin using a safety razor. Long pulse 1064nm ND: YAG laser could heat the deep hair follicles while not damage the superficial skin tissue, so it's a best laser hair removal machine for dark skin, especially the type IV-VI.

To determine the safety and effectiveness of a long-pulsed Nd:YAG laser at 1064 nm in effecting long-term hair reduction in patients with darkly pigmented skin. The laser energy is delivered using long pulses which are converted into heat in the tissue. A retrospective study of 805 consecutive laser-assisted hair removal treatments, conducted on 75 patients by means of either a long-pulsed Nd:YAG, a long-pulsed alexandrite, or a long-pulsed diode laser is reported.  C Laser-assisted hair removal: state of the art. Adverse effects included mild to moderate treatment pain and rare occurrences of vesiculation and transient pigmentary alteration without fibrosis or scarring.  VGLittler 2018 May 31;3(5):5896-5902. doi: 10.1021/acsomega.8b00040. Nd Yag Laser Hair removal The Nd Yag long pulse laser can be used safely on all skin types, including tanned. To determine the safety and effectiveness of a long-pulsed Nd:YAG laser at 1064 nm in effecting long-term hair reduction in patients with darkly pigmented skin. Nd:YAG laser may be used for hair removal in any location including underarms, bikini line, face, neck, back, chest and legs. 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. Laser wavelength is a key factor influencing treatment efficacy and complication rates. They also provide information about variations in clinical response at different body locations. Global clinical grading scores of comparable before-after treatment photographs were determined by 2 independent medical assessors during each laser session and 1, 3, 6, and 12 months postoperatively. All Rights Reserved. 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. to download free article PDFs, A contact sapphire-tipped cooling device was used to protect the skin during laser irradiation with a rhomboid scanner that placed adjacent nonoverlapping 5-mm spots over the treatment area (Lyra; LaserScope, San Jose, Calif). A mean fluence of 50 J/cm2 was used to treat axillary hair in 8 patients, whereas a mean fluence of 45 J/cm2 was used on the legs in 4 patients (Table 1).  NLAlster Global clinical evaluations of hair loss and extent of hair regrowth using side-by-side comparison photographs were performed by 2 independent medical assessors at each visit with the use of the following hair reduction grading system: 0 indicates less than 25%; 1, 25% to 50%; 2, 51% to 75%; 3, 76% to 90%; and 4, greater than 90%. Further complicating the process, it is not yet known which portion of the hair follicle is primarily responsible for hair growth and whether the integrity of the entire follicular epithelium is essential to the hair growth process.  S Alexandrite laser hair removal is safe for Fitzpatrick skin types IV-VI.  MFerranti NIH Please visit www.sciton.com/products/clearscan-yag and www.cutera.com for more information. A retrospective study of 805 consecutive laser‐assisted hair removal treatments, conducted on 75 patients by means of either a long‐pulsed Nd:YAG, a long‐pulsed alexandrite, or a long‐pulsed diode laser is reported. But patients who have used this laser reported feeling more discomfort during the treatment process.  S Long-term epilation using the EpiLight broad band, intense pulsed light hair removal system. Accepted for publication December 27, 2000. Both long-pulsed alexandrite and long-pulsed diode laser systems are effective in the treatment of unwanted hair, and they are more efficacious than Nd:YAG laser. (Figure 4). Comparative Study of Diode Laser Versus Neodymium-Yttrium Aluminum: Garnet Laser Versus Intense Pulsed Light for the Treatment of Hirsutism. To reduce epidermal energy absorption relative to follicular absorption, longer-wavelength lasers are best used.  MFarinelli 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. A series of 3 long-pulsed (50-millisecond) 1064-nm Nd:YAG laser treatments at fluences ranging from 40 to 50 J/cm. The occurrence of side effects was not significantly different between three laser systems. Adverse effects (calculated from all 60 treatment sessions) were limited to mild to moderate treatment pain in 90% of treatment sites, transient pigmentary alteration in 5% (exposed facial or leg areas only; average duration, 4 weeks), and vesiculation in 1.5%. Alizadeh N, Ayyoubi S, Naghipour M, Hassanzadeh R, Mohtasham-Amiri Z, Zaresharifi S, Gharaei Nejad K. Int J Womens Health. Long-pulsed (50-millisecond) 1064-nm Nd:YAG laser irradiation can achieve rates of hair reduction equivalent to those of other long-pulsed red and infrared laser and intense pulsed-light systems. Treatment parameters for Wart using long pulse Nd YAG laser .  FDovale Fast repetition rates and large coverage areas allow large areas of the body to be treated quickly. Private practice, ambulatory care facility. Despite this monumental obstacle, most of the available lasers and intense light sources can achieve a marked delay in the regrowth of unwanted hair (typically 3-9 months), although longer delays have been observed.1-11 In addition, laser-assisted hair removal is associated with low treatment discomfort, and large body areas can be treated expeditiously, since follicles need not be targeted individually (as is the case with electrolysis).12,13 Paramount to the success and acceptability of lasers for epilation has been the substantial safety margin afforded by most systems, with transient and mild adverse effects being normal.14. “For women or men of color interested in doing laser hair removal, the most important thing is to make sure they are getting treatments with a … Safe for All Skin Types Lask Further hair loss was seen 1 month after the second (C) and 6 months after the third (D) treatment session.
