Laser hair removal has become a standard of care for both men and women worldwide. It is one of the most popular aesthetic procedures. Discover the power of the most well-researched hair removal brands, which provide a quick, effective, and comfortable method for permanent hair removal (including tanned and dark skin).
There is a growing demand for safe, long-lasting, and effective hair reduction for aesthetic and medical reasons. Epilation by plucking or waxing, depilation by shaving, chemical depilatories, and laser and intense pulsed light (IPL) systems are all options for hair removal.
Laser hair removal technology used in professional settings are the 694 nm ruby laser, the 800 nm diode laser, the 755 nm Alexandrite laser, and the 1,064 nm Neodymium doped: yttrium aluminum garnet (Nd:YAG) laser, intense pulsed light (IPL), and radiofrequency.
The types of laser available for at-home laser hair removals are Diode and IPL.
755 nm Alexandrite Laser
This laser is one of the most widely used hair removal lasers, and it is one of the fastest types of laser. It is a good choice for treating larger body areas in patients with a light-to-olive complexion.
Alexandrite lasers are powerful equipment that should only be used by a trained practitioner, which is why they’re common in hair removal salons.
Alexandrite crystals emit energy, which corresponds to the central melanin absorption spectrum. It has a more prominent spot size with slightly deeper penetration. This is not suitable for dark skin.
Examples of Alexandrite lasers are: GentleLASE 755nm Alexandrite Laser, 2007 Cynosure Apogee Elite ELMD, 2017 Cutera Excel HR, 2018 Cynosure Picosure with 755nm & 532nm, IDS Daeshin Shiny, 2015 Quanta Systems Light A Star EX – UltraWave II, 2015 Syneron – Candela Alex Trivantage, 2005 Candela Mini Gentlelase, 2009 Candela Gentlemax, Candela GentleLASE Laser 755 nm
Long-Pulsed 694 nm Ruby Laser
The ruby laser is the oldest laser used for hair removal. It is best for patients with dark hair and fair skin. It is not recommended for patients with dark skin or anyone recently exposed to the sun.
For more than 30 years, dermatologists have used ruby lasers to treat tattoos. In Japan, the Toshiba normal-mode ruby laser has been used to treat tattoos and pigmented lesions for over ten years. Dr. L. Goldman developed the first ruby laser in the 1960s. A flashlamp-pumped, normal-mode ruby laser was primarily used to remove tattoos and pigmented skin lesions. Dr. Rox Anderson of Harvard Medical School revolutionized the ruby laser for hair removal. He created the ruby laser for hair removal with the same wavelength and similar fluences, pulse widths, and spot sizes as these older ruby laser models.
This is an old-fashioned type of laser that no one uses with other available options.
800 nm Diode Laser
Like the Alexandrite laser, this also produces a list in the center of the melanin absorption spectrum. It has a greater depth of penetration than the two earlier lasers. This can be used for darker skin but is still not the preferred choice.
High energy delivery into the skin is critical to successful diode laser hair removal. This energy is selectively absorbed by the melanin surrounding the hair follicle and has no effect on the surrounding tissue.
This laser utilizes a single wavelength of light with a high rate of abruption in melanin. When melanin heats up, it destroys the root and reduces blood flow to the follicle, effectively stopping hair growth. High-quality laser hair removal machines use refrigeration contact cooling to protect the skin’s surface, making the treatment more comfortable and pain-free for patients. Diode lasers produce high frequency, low fluence pulses that are safe for all skin types to use.
Examples of Diode lasers are: 2015 Cynosure Palomar Vectus High-Speed Diode Laser Hair Removal, 2011 Lumenis Lightsheer Duet, 2015 Alma Harmony XL PRO, 2015 Cynosure Icon, 2014 Lumenis Lightsheer ET, 2013 Cynosure Palomar Vectus High-Speed Diode Laser Hair Removal, Ellman Cheveux Diode 810 nm Laser Hair Removal, 2017 Venus Concepts Venus Velocity Hair Removal, 2007 Prowave 770, 2007 Lumenis Lightsheer ET, 2010 Lasertel Noveon LS1100-4 Diode Laser
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
