Introductory Remarks

The significance of our latest laser technology is for mild treatment of body parts and for hair elimination that can not be overemphasized, as this discipline keep on growing in popularity.

Alexandrite Laser

The alexandrite laser emits power at a wavelength of 755 nm – properly in the absorption spectrum for melanin. As melanin is the goal chromophore for hair elimination, this makes the laser a tremendous tool for getting rid of the unwanted hair. Several organizations have checked out the effectiveness and the facet outcomes of the alexandrite laser for hair elimination. Most reviews suggest that the alexandrite is similarly as powerful because the diode laser for hair elimination for pores and skin of various sorts. With lighter hair, the alexandrite outperforms the YAG laser technology and has be known to be much less painful than it too.

Melanin Absorption Spectrum

There are both upsides and downsides to the usage of a laser that has a wavelength with excessive absorption with the aid of using melanin. Laser power from the alexandrite can be correctly absorbed with the aid of using the melanin that is in the hair shaft, however it could additionally be absorbed with the aid of using the melanin present in the dermis. Absorption with the aid of using melanin within the pores and skin through laser technology can bring about hypo-pigmentation. In fact, the Q-switched model of the alexandrite may be very correctly used for pigment elimination in tattoos and lentigines.

Known Effects

Post-inflammatory hyper-pigmentation also can be visible within the darker pores and skin variation while the usage of the alexandrite laser. Most of those headaches are reversible. Patient choice desires to be accomplished carefully. In most of these procedures, we seldom use the alexandrite on pores and skin type IV and darker. When it’s used on those darker pores and skin type IV, pigmentary facet outcomes may be expected. In general, maximum of those are brief in nature.

Alternative Way Around Alexandrite Laser

Another way of lowering pigment occurrence with the alexandrite is to enhance growth cooling to the epidermis. Most alexandrite structures have adjustable cooling mechanisms, permitting the person to have an increased duration of the cryogen spray while the usage of laser on darker pores and skin type IV, or lengthening the touch time of a cooling tip. The beams of cooling are obvious with a cryogen spray length of 20 to 60 ms. No delivered gain became visible with a sprig length longer than 60 ms. Another way of making the alexandrite laser much more person–pleasant for darker pores and sensitive skin is its fairly constant pulse width. Most of the diode lasers now have adjustable pulse widths, within the splendid lengthy pulse range. The traditional alexandrite has a pulse width of 2 to 40 ms, while a number of the lengthy-pulsed diodes have pulse widths up to 1 to 1,000 ms. This has the capability to make the diode a greater “epidermally protective” laser hair elimination system.

75nm Laser Beam

It has been confirmed that with the aid of using lengthening the pulse rate length at the 755 nm laser, there has been a fashion in the direction of much less post-remedy erythema and pigmentation without the sacrifice of efficacy.

YAG Laser Technology

YAG laser remedy is powerful for leg hair elimination, as it is said that Unwanted hair can create psychological annoyance to any person.

The aim of this technology is to have a look at or to examine the lengthy–time period efficacy and protection of lengthy-pulsed YAG and alexandrite lasers, each in my view and in mixture, reduces hair re-growth. 

YAG laser with 12-mm spot length keeps up with the pulse duration of 755 nm alexandrite laser with 12-mm spot pulse speed. Whereas, 755 nm alexandrite laser with 18-mm spot length uses a mixture of lengthy-pulsed 1064 nm

YAG laser and 755-nm Alexandrite Together

As there are many laser technologies, let’s see how it works: 9% ± 19.0% for the 12-mm spot length alexandrite laser, 84. There is a chance that ± 12.4% for the 18-mm spot length alexandrite laser, 73.6% ± 11.4% for the YAG laser, and 77.8% ± 15.9% for mixture remedy (P <.05 with the aid of using evaluation of variance). Despite different research outcomes displaying greater efficacy of the alexandrite instead of the YAG laser, our trial consequences confirmed no vast distinction among the two of them.
