Short Pulse Lasers for Hair Removal
When it comes to the short listing of most effective laser, patient is generally perplexed. QS:Nd:YAG lasers are the prototypes of short pulse QS lasers. Two processes are generally employed while using YAG lasers.
Procedure in short pulse lasers
-
Just after waxing of hairs the area to be treated by laser hair removal equipment is exogenously treated with carbon suspension and later the said area is irradiated by extremely short micro second pulses (approx 10nano seconds) gauged at low energy fluence (2-3J/cm2). Carbon suspension smearing the skin work as chromophore. When the area is treated with short pulses of Yag laser, photo thermal and photomechanical processes causes the destruction of hair follicles.
-
But if carbon suspension is not used the endogenous melanin pigment is used as chromophore. This is done alternatively. Laser hair removal system is repetitively used at 1-10 Hz and at much higher energy density like8-10 J/cm2
Advantages of Short Pulse Lasers
The main advantage of the short pulsed lasers is that these can be effectively used for hair removal for persons not having ideal skin and hair color. This is achieved by the help of carbon suspension which acts as an external chromophore. Short pulse laser hair removal procedure is speedy with a repetitive rate of 10 Hz.
Disadvantages of Short Pulse Lasers
-
It is more time consuming as compared to the long pulsed lasers.
-
Some people find the treatment method messy because of carbon particles and hair fragments scattering in the surrounding place.
-
According to some there is no added benefit when using carbon and waxing prior to treatment.
Conclusion
This method provides efficient laser hair removal for red, gray and light hairs. The long term effectivity of short pulsed lasers has not been established but still it remains a good choice for people not having the characters of an ideal candidate.
