755 nm Alexandrite Laser

This is an antiquated type of laser that no one uses with other options that are available.

1,064 nm Long-Pulsed Nd:YAG Laser

This is the laser with the deepest penetration level. This is the preferred laser for dark skin because of fewer side effects.

Examples of Nd:YAG Lasers are: 2006 Reliant Solta Fraxel, 2005 Lumenis Quantum Nd Yag 1064, 2000 Lumenis VersaPulse PowerSuite, 2007 Lumenis Lightsheer ET, 2008 Sybaritic SkinClear, 2009 Cynosure Elite MPX, 2009 Radiancy SpaTouch ii Portable Hair Removal Laser, 2010 Cynosure Hoya ConBio Revlite Q-Switched with 532, 582, 650 & 1064, 2011 Aerolase Lightpod Neo Nd Yag 1064nm, 2012 Viora Reaction Radio Frequency Laser
