Where is the Alexandrite Laser Utilized?
Alexandrite lasers are effective tools and also should just be made use of by an experienced expert, consequently they are often utilized in hair removal beauty salons. There are currently No FDA accepted house laser hair removal gadgets that contain the Alexandrite laser
What is the Alexandrite Laser?
An Alexandrite Laser is a kind of LASER (light amplification by promoted exhaust of radiation) that produces high energy light through an alexandrite crystal. As the light go through the alexandrite crystal, a beam of light 755 nm long is generated.
Note: The length of the beam of light identifies exactly how far right into the skin the laser passes through.
The shade 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.
Along with hair removal, Alexandrite Lasers are made use of for:
Treating age places
Dealing with crawler blood vessels
Treating vascular birthmarks

Exactly how is it Different from Other Lasers?
What is the difference in between the Alexandrite Laser and other lasers? Besides the shade, the wavelength of the light is the only thing that alters.
For example, the Alexandrite Laser discharges a red beam of light that is 755 nm. A diode laser, on the other hand, discharges a 810 nm laser beam of light and a YAG laser releases a beam at 1064 nm.
Wavelength Contrast of the Different Lasers
488 nm or 514.5 nm.
No longer made use of for hair elimination – the gadget bored and also inefficient for hair elimination.
Efficient as well as secure on individuals with light, light skin.
Safe as well as efficient on all skin types (from 1-7 on the Fitzpatrick scale).
Pulsed Diode Selection.
Effective on pale to tool skin (I as much as IV on the Fitzpatrick scale).
Nd: YAG Laser.
Specifically made for darker skin kinds, though reliable on all skin kinds.
Extreme Pulsed Light.
500 to 1200nm.
For pale to tool type skin (this is not a laser however is still made use of for hair elimination).
Benefits of the Alexandrite Laser.
It is taken into consideration the most reliable laser for use with all hair and also skin kinds, as the laser does not impact darker skin types as long as other lasers. Just like all other lasers, it is best with white and extremely light skin, and also has verified most reliable with the fine, slim hairs that most of the other sorts of laser can not get rid of.
The wavelength of light sent out from the Alexandrite Laser is easily taken in by the melanin (pigment cells) in your hair, which creates those cells to be heated up as well as ultimately damaged.
Keep in mind: For extremely dark skin types, the most effective alternative is the Nd: YAG laser, as the light beam’s additional length will certainly pass through the hair follicles without impacting the skin pigment as a lot.
Alexandrite Laser Effectiveness.
With the Alexandrite Laser, there is a hair clearance price of approximately 70% after the suggested variety of therapies– normally 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 decrease efficiency.
It is also taken into consideration the fastest of the lasers, eliminating huge swaths of hair in less sessions. For patients curious about dealing with bigger body locations (such as the belly, upper body, back, shoulders, or legs), it’s commonly advised to make use of the Alexandrite Laser.
Alexandrite Lasers are one of the only lasers advised for dealing with hypertrichosis, additionally known as “Ambras syndrome”.
Alexandrite vs. Diode Lasers.
Among the most preferred types of lasers for laser hair removal is the pulsed diode laser, which has a beam of light just a little longer than the Alexandrite Laser.
In a 2001 research study , both lasers were contrasted to see which generated the best long-lasting outcomes. Alexandrite Lasers created hair growth to be decreased by 85%, while diode lasers only generated an 84% reduction. 4 treatment sessions with both lasers created a 90% decrease in hair development for as much as 12 months.
In 2006, a research study was done into the performance of both lasers, as well as it was located that both lasers got the job done with equal performance. However, diode lasers were more probable to trigger adverse effects, with a 28.9% opportunity of problems compared to the 9.5% possibility with Alexandrite Lasers.

Are there negative 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 risk of hypopigmentation (skin lightening in spots that are treated by the laser). The Alexandrite Laser is NOT one of the most efficient for dark-skinned individuals, as pointed out above.
Also among those with lighter skin, there is a threat of the pigment being destroyed from the skin. On the flip side, there is even a danger that the skin will certainly OVER-produce melanin as a result of the light, which might cause dark spots on your skin.
Discomfort is common throughout the treatment, though it’s typically relatively minimal. A cooling gel is typically used once the location is treated, helping to lower discomfort and also stop swelling.
There is frequently a little bit of swelling as well as itching following the treatment, but that must go away after a couple of days. The skin may turn red, but it will only burn if the laser is inaccurately utilized.
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 Accepted?
If you’re thinking about laser hair removal with an Alexandrite Laser, you need to see to it that the laser being made use of has been authorized by the FDA. Alexandrite laser hair elimination was authorized “clear to market” in 1997.
There are three brand names of FDA-approved “irreversible hair decrease” Alexandrite lasers prominent on the market today:.
If your skin doctor advises an additional brand name of Alexandrite Laser, it deserves doing your study to make certain that it is an FDA-approved tool.
Suppliers REQUIREMENTS receive FDA clearance prior to marketing their devices, and also you can discover which brands have obtained approval by checking out the FDA’s 510( k) database. Follow this web link to figure out a lot more.
Alexandrite Laser Clinical Information.
Having actually been removed by the FDA for marketing in 1997, the Alexandrite laser has actually had a number of researches done to determine its efficacy. Studies globally wrap up that the Alexandrite laser as an effective method of hair elimination.
Right here are 3 primary research studies as recommendation:-.
Dark Skin Adverse Effects Research Study.
Negative Effects Free.
150 clients (18 males and also 132 females) with skin kind from IV to VI were treated with the Alexandrite laser – negative effects happened in just 2% of situations. Connect to examine.
This outcome is consistent with another study of adverse effects in lighter skin kinds, recommending that you disappear statistically most likely to have side effects from the Alexandrite laser if you have darker skin colour than if you have pale skin.
Pulsed Alexandrite Laser Hair Elimination Efficiency Research.
126 patients went through a 15 month duration of treatment with pulsed Alexandrite modern technology. Time between sessions during the therapy varied from 4 weeks to 3 1/2 months.
The outcomes of the research revealed an average decrease in hair amount of higher than 88% 3 months after the last treatment. Connect to study.
Decrease in Hair Count.
Comparison of Alexandrite and also Electrolysis for Hair Removal.
Reduction in Hair Matter.
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%. Connect to research.
Electrolysis showed a reduction in hair count of just 35%. It must be pointed out that the technique of electrolysis was galvanic instead of thermolysis.
Galvanic is an older out-of-date version of Electrolysis and not comparable with the speed and performance of modern day electrolysis methods.
