Long-Term Hair Removal with a Novel 650-microsecond Nd:YAG Laser
David J. Friedman, MD, Dermatology, New York, NY & Jerusalem, Israel
A study was conducted in 2006/2007 to evaluate a pulsed Nd:YAG 1064nm laser for long-term laser hair removal. Unlike conventional lasers and light-based devices in the field, the laser in this evaluation utilizes a unique 650-microsecond pulse duration with no skin cooling, gels or anesthetics. Ten female subjects and one male subject with Fitzpatrick Skin Types II through VI were treated and the long-term results indicated >75% clearance in the majority of cases; those treated 5 to 7 times reported 82% clearance on average and as high as 93%. These assessments were made, on average, 8.3 months after the subjects’ final treatment session.
Efficacy and Safety of a 650-microsecond Pulsed Portable ND:YAG Laser for Hair Removal
One half of each axilla of six female participants was treated and the other half was monitored as a control. The treatment sites were treated with a fluence of either 21 J/cm2 or 36 J/cm2 using an Nd:YAG laser with a wavelength of 1064 nm and a pulse duration of 650-microseconds.
Laser Hair Removal Using a 650-Microsecond Pulsed ND:YAG Laser: A Study of 298 Patients
A 650-microsecond Nd:YAG laser has recently been found to have comparable results to longer pulse duration Nd:YAG lasers without skin cooling measures.
Treatment of PFB with a 650-microsecond Pulsed Nd:YAG 1064nm Laser
A fluence of 20-25 j/cm2 was used with a pulse duration of 650-microseconds, spot size of 6mm and a repetition rate of 1 Hz.
