Laser hair removal for different types of laser equipment is available. The choice of laser hair removal equipment and selecting the appropriate parameters to achieve best results from laser hair removal must be individualized according to patient needs. Here is a brief discussion about the various types of laser hair removal equipment currently available;
Laser hair removal for different types of laser equipment is available. The choice of laser hair removal equipment and selecting the appropriate parameters to achieve best results from laser hair removal must be individualized according to patient needs. Here is a brief discussion about the various types of laser hair removal equipment currently available;
“Alexandrite laser”
Laser has the ability to penetrate deep into the dermis. The result of heat accumulation in the hair disables hair follicles in the active growth phase that allows you to get a laser hair removal.
Specifications
Wavelength: 755
Pulse width: 2-20
Fluence: 10-40
Field Size: 5-10
Repetition rate: 1-5
Available devices
Three alexandrite lasers are available. These include,
Apogee-40 (Cynosure, Chelmsford, Mass)
EpiTouch Alex (formerly CES Sharples, now Lumenis, Santa Clara, Calif.)
GentleLASE (Candela, Wayland, Mass)
Disadvantages
Hair removal is a short-term
Adverse effects in 2% of patients with dark Alexandrite laser.
“Laser Diode”
The diode laser is a very effective device. Laser activates the production of small diodes or semiconductors that are arranged to produce light. The diode laser has a wavelength longer than others who use the laser can improve treatment results in darker skin types.
Specifications
Wavelength: 800-810
Pulse width: 5-30
Fluence: 10-40
Size of land: 9
Repetition rate: 1
Available devices
Several 800-nm diode laser has been granted FDA approval. These include;
Apex-800 Iriderm (IRIDEX, Mountain View, Calif.)
LaserLite (ANGUAGES, Andover, Mass)
SLP100 (Palomar, Burlington, Mass)
Epist (NIDEK, Fremont, Calif.)
MeDioStar diode laser (Aesculap-Meditec, Jena, Germany) (pending FDA approval)
Advantages
Wavelength safeguards achieving good results for darker skin types.
Deep penetration depth and direction of the hair follicles.
Disadvantages
In some cases after treatment with diode laser some patients developed urticaria. This is a severe allergic reaction in the skin similar to hives and can be managed by therapy with anti-allergic drugs.
“Q-switched Nd: YAG laser”
This laser has the ability to deliver two different wavelengths of light. One is an invisible infrared light used for deeper penetration. This wavelength is used to reach deeper hair follicles. The other wavelength, a green light is used to treat hair follicles to the surface. In both cases, the Q-switching device emits rapid bursts of laser light to the treatment area.
Specifications
Wavelength: 1064
Pulse width: 10-50
Fluence: 20-100
Field Size: 3-5
Repetition rate: up to 10 Hz
Advantages
Availability of surface cooling and protecting the epidermis due to surface cooling and long pulse duration of these lasers.
Long-term studies show that these laser systems can achieve a significant delay in the regeneration of hair
Nd: YAG 1064 nm system can be better for patients darkly pigmented
Disadvantages
The waxing and the application of carbon lotion is cumbersome.
No clinical data to support additional benefits are obtained when the pre-treatment waxing or carbon suspension is used.
No proven effective long-term results.
Available devices
Carbon suspension Q-switched lasers SoftLight (ThermoLase, London, England)
Q-switched Nd: YAG laser MedLite IV (Hoya ConBio, Fremont, Calif.)
Long pulse Nd: YAG laser, for example, LaserScope (plucking, Phoenix, Ariz.)
“Ruby laser”
This laser emits a red beam that looks for the target melanin inside the hair and hair follicles adjacent. Due to its melanin targeting these are best suited for people who have light skin and dark hair.
Specifications
Wavelength: 694
Pulse width: 0.85-3
Fluence: 5-40
Field Size: 3-10
Repetition rate: 0.5-1.2
Available devices
Three normal modes, 694-nm ruby lasers are commercially available for laser hair removal. These include the E2000 (Palomar, Burlington, Mass) (deleted from the FDA), Ruby EpiPulse (CES Sharples earlier, now the pure light of Lumenis, Santa Clara, Calif.), RubyStar (Aesculap-Meditec, Jena, Germany)
Advantages
Achieve long term hair removal.
The E2000 series is equipped with a cooled sapphire Epiwand epidermal hand that serves as a coolant. Other devices are also equipped with cooling devices built in to minimize the potential for burns and other side effects laser hair removal.
