long pulsed nd:yag laser hair removal

Five sessions at 4‐ to 6‐week intervals were performed. Epub 2008 Feb 6. Subjective patient reports and adverse effects were also recorded at each follow-up visit. But patients who have used this laser reported feeling more discomfort during the treatment process. 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.  S Long-term epilation using the EpiLight broad band, intense pulsed light hair removal system. Thus, only lasers emitting energy with wavelengths ranging from 630 to 1100 nm are potentially capable of irradiating the entire length of anagen hair follicles, which typically extend 2 to 5 mm into the dermis.  EFSuthamjariya (Figure 4). 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 … Methods.  CMWheeland 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 choice of laser system used was based on each laser’s availability and working condition and randomly assigned rather than on … Patients  Facial hair before treatment (A) and 1 month after second 1064-nm Nd:YAG (50-millisecond) laser treatment at an average fluence of 40 J/cm2 (B). Lasers Surg Med 2003;32:399– 2011;26:623–6. 2001;137(7):885–889.  AGalimberti When a 1,064-nm long-pulsed Nd:YAG laser is used on the skin, a strong laser pulse is absorbed by red structures or raised pigmented structures such as cutaneous blood vessels or hair, or DPN or senile warts. Administer a single laser shot in the center of the wart followed by laser shots around the circumference, ending with an additional single shot in the center of the wart. Tanzi EL, Alster TS. Objective  HHS 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%. Substantial hair reduction was seen after each of the 3 treatment sessions. USA.gov. Please enable it to take advantage of the complete set of features! Lasers Med Sci.  CAAlster Nd Yag Laser Hair removal The Nd Yag long pulse laser can be used safely on all skin types, including tanned. https://jamanetwork.com/journals/jamadermatology/fullarticle/478428 Olsen Compared with other cutaneous organelles, hair follicles represent a unique challenge for implementation of the theory of selective photothermolysis, based largely on the fact that it remains unclear which portion of the follicle is the preferred target to effect hair destruction. Three-millimeter skin punch biopsy specimens were taken from within each of the 3 different treatment areas (face, axilla, and leg) at baseline, immediately after laser irradiation, and 1 and 6 months after the final laser treatment in 3 patients. Axillary hair was substantially more responsive to laser irradiation than was hair located on the legs and face. Depending on the pulse duration and energy density, this may result in the coagulation or blasting of these structures. Adverse effects included mild to moderate treatment pain and rare occurrences of vesiculation and transient pigmentary alteration without fibrosis or scarring. They also provide information about variations in clinical response at different body locations. No topical cooling gel or anesthetic cream was used.

One (C) and 6 (D) months after the third treatment, prolonged hair reduction is seen.  WAAnderson  RR Damage to hair follicles by normal-mode ruby laser irradiation. Kolinko  |  Solid-Phase Synthesis of Peptide-Conjugated Perylene Diimide Bolaamphiphile and Its Application in Photodynamic Therapy. 2003 Dec;14(4):243-7. doi: 10.1080/09546630310004171.  TS Optimizing treatment parameters for hair removal using a topical carbon-based solution and 1064-nm Q-switched neodymium:YAG laser energy.
