Where is the Alexandrite Laser Used?
Alexandrite lasers are effective equipment and needs to only be made use of by a skilled practitioner, consequently they are often used in hair removal beauty salons. There are presently No FDA authorized home laser hair elimination tools which contain the Alexandrite laser
What is the Alexandrite Laser?
An Alexandrite Laser is a kind of LASER (light boosting by stimulated discharge of radiation) that emits high power light through an alexandrite crystal. As the light travel through the alexandrite crystal, a beam of light 755 nm long is produced.
Keep in mind: The size of the beam of light establishes exactly how much into the skin the laser penetrates.
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 in short pulses. This is what makes it reliable for hair removal.
In addition to hair removal, Alexandrite Lasers are used for:
Dealing with age spots
Dealing with spider veins
Dealing with vascular birthmarks

How is it Various from Other Lasers?
What is the difference in between the Alexandrite Laser as well as other lasers? Aside from the shade, the wavelength of the light is the only thing that changes.
For example, the Alexandrite Laser emits a red beam that is 755 nm. A diode laser, on the other hand, emits a 810 nm laser beam of light as well as a YAG laser gives off a beam at 1064 nm.
Wavelength Comparison of the Various Lasers
488 nm or 514.5 nm.
No more used for hair removal – the device bored and also inadequate for hair elimination.
Effective and safe on individuals with light, pale skin.
Safe as well as reliable on all skin kinds (from 1-7 on the Fitzpatrick range).
Pulsed Diode Array.
Reliable on pale to medium skin (I up to IV on the Fitzpatrick scale).
Nd: YAG Laser.
Especially made for darker skin kinds, though reliable on all skin types.
Extreme Pulsed Light.
500 to 1200nm.
For light to medium kind skin (this is not a laser yet is still made use of for hair removal).
Benefits of the Alexandrite Laser.
It is considered the most effective laser for use with all hair as well as skin kinds, as the laser does not influence darker skin types as much as various other lasers. Just like all other lasers, it is best with white and extremely light skin, and has actually proven most effective with the penalty, slim hairs that a lot of the other types of laser can not remove.
The wavelength of light given off from the Alexandrite Laser is conveniently taken in by the melanin (pigment cells) in your hair, which causes those cells to be warmed and inevitably destroyed.
Keep in mind: For really dark skin kinds, the most effective alternative is the Nd: YAG laser, as the light beam’s additional size will pass through the hair roots without impacting the skin pigment as much.
Alexandrite Laser Efficiency.
With the Alexandrite Laser, there is a hair clearance price of approximately 70% after the advised number of therapies– normally in between 6 and also 8 for thinner hair, or 8 to 12 for thicker, darker hair. See medical studies to find out more on hair reduction effectiveness.
It is also considered the fastest of the lasers, removing huge swaths of hair in less sessions. For patients interested in dealing with bigger body locations (such as the belly, upper body, back, shoulders, or legs), it’s frequently advised to utilize the Alexandrite Laser.
Alexandrite Lasers are one of the only lasers recommended for dealing with hypertrichosis, likewise known as “Ambras disorder”.
Alexandrite vs. Diode Lasers.
Among the most prominent sorts of lasers for laser hair removal is the pulsed diode laser, which has a light beam only slightly longer than the Alexandrite Laser.
In a 2001 research , the two lasers were compared to see which generated the very best lasting results. Alexandrite Lasers caused hair growth to be reduced by 85%, while diode lasers just produced an 84% decrease. 4 therapy sessions with both lasers created a 90% decrease in hair development for as much as year.
In 2006, a research was done into the effectiveness of both lasers, and also it was discovered that both lasers got the job done with equivalent performance. Nonetheless, diode lasers were more probable to create side effects, with a 28.9% possibility of problems compared to the 9.5% chance with Alexandrite Lasers.

Are there adverse effects of using the Alexandrite Laser? Unfortunately, similar to all lasers, there are some side effects.
For those with very dark skin, there is a danger of hypopigmentation (skin lightening in patches that are treated by the laser). The Alexandrite Laser is NOT one of the most effective for dark-skinned individuals, as stated above.
Even among those with lighter skin, there is a risk of the pigment being ruined from the skin. On the other side, there is also a risk that the skin will OVER-produce melanin as a result of the light, which might bring about dark spots on your skin.
Discomfort is common throughout the therapy, though it’s usually fairly marginal. A cooling gel is commonly used once the location is treated, assisting to reduce pain and also prevent swelling.
There is often a little swelling and also itching complying with the treatment, but that ought to vanish after a couple of days. The skin may redden, but it will only burn if the laser is inaccurately utilized.
There is a really small chance (10%) that there will certainly be wounding, yet the contusions will certainly discolor by themselves.
Is the Alexandrite Laser FDA Approved?
If you’re considering laser hair removal with an Alexandrite Laser, you require to make certain that the laser being made use of has actually been authorized by the FDA. Alexandrite laser hair elimination was accepted “clear to market” in 1997.
There are three brands of FDA-approved “permanent hair reduction” Alexandrite lasers prominent on the market today:.
If your dermatologist advises an additional brand of Alexandrite Laser, it deserves doing your research study to make sure that it is an FDA-approved tool.
Suppliers MUST receive FDA clearance before marketing their tools, as well as you can discover which brand names have actually received approval by looking into the FDA’s 510( k) data source. Follow this web link to discover extra.
Alexandrite Laser Scientific Data.
Having actually been gotten rid of by the FDA for advertising and marketing in 1997, the Alexandrite laser has had a number of research studies done to identify its efficacy. Research studies universally end that the Alexandrite laser as a reliable technique of hair removal.
Here are three main studies as recommendation:-.
Dark Skin Adverse Effects Study.
Adverse Effects Free.
150 individuals (18 males and 132 women) with skin type from IV to VI were treated with the Alexandrite laser – side effects occurred in just 2% of cases. Link to study.
This outcome follows one more study of negative effects in lighter skin types, recommending that you disappear statistically most likely to have negative effects from the Alexandrite laser if you have darker skin colour than if you have light skin.
Pulsed Alexandrite Laser Hair Removal Effectiveness Study.
126 clients underwent a 15 month period of therapy with pulsed Alexandrite technology. Time in between sessions throughout the treatment varied from 4 weeks to 3 1/2 months.
The results of the study showed an average decrease in hair quantity of above 88% 3 months after the final treatment. Connect to research.
Decrease in Hair Count.
Contrast of Alexandrite and also Electrolysis for Hair Removal.
Decrease in Hair Count.
After 3 sessions of Alexandrite laser hair elimination at 4 week periods, clients revealed a reduction of hair at 6 months after therapy of 74%. Connect to examine.
Electrolysis showed a reduction in hair matter of only 35%. It must be pointed out that the method of electrolysis was galvanic in contrast to thermolysis.
Galvanic is an older out-of-date version of Electrolysis and also not equivalent with the rate and performance of modern electrolysis techniques.
