Where is the Alexandrite Laser Made Use Of?
Alexandrite lasers are powerful tools and also ought to only be used by a trained specialist, therefore they are frequently used in hair removal beauty parlors. There are presently No FDA authorized residence laser hair removal tools that contain the Alexandrite laser
What is the Alexandrite Laser?
An Alexandrite Laser is a sort of LASER (light amplification by promoted emission of radiation) that gives off high energy light via an alexandrite crystal. As the light travel through the alexandrite crystal, a beam of light 755 nm long is generated.
Keep in mind: The length of the beam identifies just how far into the skin the laser penetrates.
The shade of the laser light is red.
Alexandrite Lasers can be set on Q-switching mode, which creates the laser to generate a high-energy beam in other words pulses. This is what makes it efficient for hair removal.
Along with hair elimination, Alexandrite Lasers are utilized for:
Treating age places
Treating spider blood vessels
Dealing with vascular birthmarks

Just how is it Different from Other Lasers?
What is the distinction between the Alexandrite Laser and other lasers? Aside from the color, the wavelength of the light is the only thing that changes.
For instance, the Alexandrite Laser releases a red beam that is 755 nm. A diode laser, on the other hand, emits a 810 nm laser beam and a YAG laser releases a beam at 1064 nm.
Wavelength Comparison of the Various Lasers
488 nm or 514.5 nm.
No longer made use of for hair elimination – the device was tedious and inefficient for hair removal.
Efficient and risk-free on people with light, pale skin.
Safe and also efficient on all skin types (from 1-7 on the Fitzpatrick scale).
Pulsed Diode Array.
Efficient on light to medium skin (I as much as IV on the Fitzpatrick scale).
Nd: YAG Laser.
Particularly produced darker skin kinds, though reliable on all skin kinds.
Extreme Pulsed Light.
500 to 1200nm.
For light to medium kind skin (this is not a laser however is still made use of for hair elimination).
Benefits of the Alexandrite Laser.
It is thought about one of the most reliable laser for use with all hair as well as skin types, as the laser does not affect darker skin kinds as long as various other lasers. Just like all other lasers, it is best with white and also very light skin, and also has confirmed most efficient with the fine, thin hairs that a number of the various other types of laser can not get rid of.
The wavelength of light emitted from the Alexandrite Laser is quickly taken in by the melanin (pigment cells) in your hair, which triggers those cells to be warmed as well as ultimately destroyed.
Keep in mind: For extremely dark skin types, the best option is the Nd: YAG laser, as the beam of light’s extra length will certainly pass through the hair follicles without impacting the skin pigment as a lot.
Alexandrite Laser Efficiency.
With the Alexandrite Laser, there is a hair clearance price of approximately 70% after the suggested variety of treatments– normally in between 6 and 8 for thinner hair, or 8 to 12 for thicker, darker hair. See medical studies to learn more on hair decrease effectiveness.
It is also considered the fastest of the lasers, getting rid of big swaths of hair in fewer sessions. For people interested in treating bigger body areas (such as the tummy, upper body, back, shoulders, or legs), it’s typically recommended to use the Alexandrite Laser.
Alexandrite Lasers are among the only lasers suggested for dealing with hypertrichosis, additionally called “Ambras disorder”.
Alexandrite vs. Diode Lasers.
One of one of the most prominent kinds of lasers for laser hair removal is the pulsed diode laser, which has a light beam just slightly longer than the Alexandrite Laser.
In a 2001 study , the two lasers were compared to see which created the most effective long-term outcomes. Alexandrite Lasers caused hair development to be minimized by 85%, while diode lasers just generated an 84% reduction. Four treatment sessions with both lasers triggered a 90% reduction in hair development for as much as year.
In 2006, a research study was done into the efficiency of both lasers, and also it was discovered that both lasers did the job with equivalent efficiency. Nonetheless, diode lasers were most likely to cause negative effects, with a 28.9% opportunity of troubles compared to the 9.5% possibility with Alexandrite Lasers.

Are there negative effects of using the Alexandrite Laser? Sadly, similar to all lasers, there are some negative effects.
For those with very dark skin, there is a risk of hypopigmentation (skin lightening in spots that are dealt with by the laser). The Alexandrite Laser is NOT the most reliable for dark-skinned people, as pointed out above.
Also among those with lighter skin, there is a threat of the pigment being damaged from the skin. On the flip side, there is even a danger that the skin will OVER-produce melanin as a result of the light, which could result in dark patches on your skin.
Discomfort is common during the treatment, though it’s typically rather minimal. A cooling gel is usually applied once the area is treated, aiding to decrease pain and avoid swelling.
There is commonly a bit of swelling and also itching adhering to the treatment, yet that should go away after a couple of days. The skin might turn red, but it will just melt if the laser is improperly used.
There is an extremely small chance (10%) that there will certainly be wounding, yet the swellings will discolor by themselves.
Is the Alexandrite Laser FDA Accepted?
If you’re considering laser hair removal with an Alexandrite Laser, you need to ensure that the laser being utilized has actually been approved by the FDA. Alexandrite laser hair elimination was authorized “clear to market” in 1997.
There are three brand names of FDA-approved “long-term hair decrease” Alexandrite lasers popular on the market today:.
EpiTouch And also.
If your dermatologist suggests another brand of Alexandrite Laser, it’s worth doing your research to see to it that it is an FDA-approved tool.
Suppliers NECESSITIES obtain FDA clearance prior to marketing their devices, as well as you can learn which brand names have actually received authorization by having a look at the FDA’s 510( k) database. Follow this link to learn more.
Alexandrite Laser Professional Data.
Having been cleared by the FDA for advertising in 1997, the Alexandrite laser has actually had a variety of research studies done to determine its efficiency. Research studies globally conclude that the Alexandrite laser as a reliable technique of hair removal.
Right here are 3 main researches as reference:-.
Dark Skin Side Effects Study.
Side Effect Free.
150 patients (18 men as well as 132 ladies) with skin type from IV to VI were treated with the Alexandrite laser – side effects took place in simply 2% of cases. Link to research.
This result is consistent with one more research of adverse effects in lighter skin types, recommending that you are no more statistically most likely to have adverse effects from the Alexandrite laser if you have darker skin colour than if you have light skin.
Pulsed Alexandrite Laser Hair Elimination Efficiency Research.
126 clients underwent a 15 month duration of therapy with pulsed Alexandrite modern technology. Time in between sessions throughout the therapy ranged from 4 weeks to 3 1/2 months.
The results of the study revealed an ordinary drop in hair quantity of above 88% 3 months after the last therapy. Link to examine.
Reduction in Hair Count.
Comparison of Alexandrite and also Electrolysis for Hair Elimination.
Decrease in Hair Count.
After 3 sessions of Alexandrite laser hair removal at 4 week intervals, individuals revealed a reduction of hair at 6 months after therapy of 74%. Link to research.
Electrolysis showed a reduction in hair count of just 35%. It should be pointed out that the technique of electrolysis was galvanic rather than thermolysis.
Galvanic is an older outdated version of Electrolysis and not comparable with the speed and also efficiency of modern day electrolysis methods.
