1. What is the Alexandrite Laser?
An Alexandrite Laser is a type of Laser (light amplification by stimulated emission of radiation) that emits high energy light through an alexandrite crystal. As the light passes through the alexandrite crystal, a beam of light 755nm long is produced.
Note: The wavelength of the beam of light determines how far into the skin the laser penetrates.
The color of the Alexandrite laser light is red.
Alexandrite Laser also available in Q-switch mode, which causes the laser to produce a high energy beam of light in short pulses. This is what makes it effective for hair removal.
In addition to hair removal, Alexandrite Laser are used for:
1) Age spot removal
2) Spider vein removal
3) Vascular birthmarks removal
2. Advantages of the Alexandrite Laser
Alexandrite Laser is considered the most efficient laser for use with all hair and skin types, as the laser does not affect darker skin types as much as other lasers. As with all other lasers, it is best with white and very light skin, and has proven most effective with the fine, thin hairs that many of the other types of laser can't eliminate.
The wavelength of light emitted from the Alexandrite Laser is easily absorbed by the melanin (pigment cells) in your hair, which causes those cells to be heated and ultimately destroyed.
Note: For very dark skin types, the best option is the Nd:YAG laser or 808nm diode laser, as the beam's extra length will penetrate the hair follicles without affecting the skin pigment as much.
3. Where is the Alexandrite Laser Used?
Alexandrite laser is powerful equipment and should only be used by a trained practitioner, therefore they are often used in laser clinic / beauty salon / SPA / beauty center.
4. Alexandrite Laser Effectiveness
With the Alexandrite Laser, there is a hair clearance rate of roughly 70% after the recommended number of treatments--usually between 6 and 8 for thinner hair, or 8 to 12 for thicker, darker hair. See clinical studies for more information on hair reduction effectiveness.
Alexandrite Laser is also considered the fastest of the lasers, removing large swaths of hair in fewer sessions. For patients interested in treating larger body areas (such as the stomach, chest, back, shoulders, or legs), it's often recommended to use the Alexandrite Laser.
Alexandrite Laser is one of the only lasers recommended for treating hypertrichosis, also known as "Ambras syndrome".
