Where is the Alexandrite Laser Used?
Alexandrite lasers are effective tools and also should just be used by a qualified practitioner, consequently they are typically used in hair elimination hair salons. There are presently No FDA accepted house laser hair elimination tools that contain the Alexandrite laser
What is the Alexandrite Laser?
An Alexandrite Laser is a type of LASER (light amplification by stimulated discharge of radiation) that gives off high power light via an alexandrite crystal. As the light go through the alexandrite crystal, a beam of light 755 nm long is created.
Keep in mind: The length of the beam of light figures out exactly how much right into the skin the laser passes through.
The color of the laser light is red.
Alexandrite Lasers can be set on Q-switching mode, which creates the laser to produce a high-energy beam simply put pulses. This is what makes it efficient for hair removal.
In addition to hair elimination, Alexandrite Lasers are utilized for:
Treating age spots
Treating spider veins
Treating vascular birthmarks

Just how is it Various from Various Other Lasers?
What is the difference in between the Alexandrite Laser and also other lasers? Aside from the color, the wavelength of the light is the only point that changes.
As an example, the Alexandrite Laser sends out a red beam of light that is 755 nm. A diode laser, on the other hand, gives off a 810 nm laser beam as well as a YAG laser discharges a beam of light at 1064 nm.
Wavelength Contrast of the Different Lasers
488 nm or 514.5 nm.
No more used for hair elimination – the device was tedious and also ineffective for hair elimination.
Reliable and also safe on clients with light, pale skin.
Safe as well as reliable on all skin types (from 1-7 on the Fitzpatrick scale).
Pulsed Diode Selection.
Reliable on pale to tool skin (I up to IV on the Fitzpatrick scale).
Nd: YAG Laser.
Particularly created darker skin types, though reliable on all skin types.
Extreme Pulsed Light.
500 to 1200nm.
For light to medium type skin (this is not a laser yet is still utilized for hair elimination).
Advantages of the Alexandrite Laser.
It is considered the most reliable laser for use with all hair and skin kinds, as the laser does not influence darker skin types as long as other lasers. Similar to all other lasers, it is best with white and also extremely light skin, as well as has confirmed most efficient with the fine, thin hairs that most of the various other sorts of laser can not get rid of.
The wavelength of light discharged from the Alexandrite Laser is quickly absorbed by the melanin (pigment cells) in your hair, which causes those cells to be warmed and also ultimately destroyed.
Keep in mind: For really dark skin types, the most effective alternative is the Nd: YAG laser, as the beam of light’s added length will certainly permeate the hair follicles without influencing the skin pigment as much.
Alexandrite Laser Efficiency.
With the Alexandrite Laser, there is a hair clearance rate of about 70% after the recommended variety of therapies– generally in between 6 and also 8 for thinner hair, or 8 to 12 for thicker, darker hair. See scientific studies to find out more on hair reduction performance.
It is likewise thought about the fastest of the lasers, removing huge swaths of hair in fewer sessions. For people thinking about dealing with bigger body areas (such as the belly, chest, back, shoulders, or legs), it’s typically suggested to use the Alexandrite Laser.
Alexandrite Lasers are among the only lasers suggested for dealing with hypertrichosis, additionally referred to as “Ambras syndrome”.
Alexandrite vs. Diode Lasers.
One of one of the most preferred kinds of lasers for laser hair removal is the pulsed diode laser, which has a light beam just a little longer than the Alexandrite Laser.
In a 2001 research , both lasers were compared to see which produced the most effective lasting outcomes. Alexandrite Lasers created hair development to be decreased by 85%, while diode lasers just generated an 84% decrease. Four treatment sessions with both lasers caused a 90% decrease in hair growth for as much as 12 months.
In 2006, a research study was done into the effectiveness of both lasers, as well as it was located that both lasers did the job with equal performance. Nonetheless, diode lasers were more probable to create adverse effects, with a 28.9% possibility of problems compared to the 9.5% chance with Alexandrite Lasers.

Exist negative effects of using the Alexandrite Laser? Regrettably, just like 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 treated by the laser). The Alexandrite Laser is NOT the most effective for dark-skinned patients, as discussed over.
Also amongst those with lighter skin, there is a risk of the pigment being destroyed 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 can bring about dark spots on your skin.
Discomfort is common during the therapy, though it’s typically fairly very little. A cooling gel is frequently applied once the area is treated, aiding to minimize pain and avoid swelling.
There is commonly a little bit of swelling and itching following the treatment, yet that should go away after a couple of days. The skin might turn red, yet it will just melt if the laser is improperly made use of.
There is an extremely small chance (10%) that there will be wounding, but the swellings will certainly fade by themselves.
Is the Alexandrite Laser FDA Approved?
If you’re thinking about laser hair elimination with an Alexandrite Laser, you need to see to it that the laser being utilized has actually been approved by the FDA. Alexandrite laser hair removal was approved “clear to market” in 1997.
There are 3 brand names of FDA-approved “irreversible hair decrease” Alexandrite lasers popular on the market today:.
EpiTouch And also.
If your dermatologist suggests one more brand name of Alexandrite Laser, it deserves doing your research study to make certain that it is an FDA-approved gadget.
Suppliers MUST receive FDA clearance before marketing their devices, and also you can learn which brands have obtained approval by checking out the FDA’s 510( k) data source. Follow this link to learn a lot more.
Alexandrite Laser Scientific Data.
Having been removed by the FDA for marketing in 1997, the Alexandrite laser has actually had a variety of studies done to identify its effectiveness. Research studies widely conclude that the Alexandrite laser as an efficient technique of hair elimination.
Here are three main studies as referral:-.
Dark Skin Side Effects Research Study.
Negative Effects Free.
150 clients (18 men and also 132 ladies) with skin kind from IV to VI were treated with the Alexandrite laser – adverse effects happened in simply 2% of situations. Connect to research.
This outcome is consistent with one more study of negative effects in lighter skin kinds, suggesting 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 Removal Efficacy Study.
126 patients underwent a 15 month period of therapy with pulsed Alexandrite technology. Time in between sessions throughout the therapy ranged from 4 weeks to 3 1/2 months.
The outcomes of the research study showed an ordinary drop in hair quantity of higher than 88% 3 months after the final therapy. Link to examine.
Reduction in Hair Count.
Contrast of Alexandrite and also Electrolysis for Hair Removal.
Decrease in Hair Matter.
After 3 sessions of Alexandrite laser hair elimination at 4 week intervals, patients revealed a decrease of hair at 6 months after treatment of 74%. Link to examine.
Electrolysis showed a reduction in hair matter of only 35%. It must be mentioned that the approach of electrolysis was galvanic rather than thermolysis.
Galvanic is an older out-of-date version of Electrolysis as well as not equivalent with the speed as well as efficiency of modern electrolysis approaches.
