Less Discomfort, Great Results And Outstanding safety
July 19, 2010
Lasers used in aesthetics are specifically attracted to a chromophore, or a colored target, selectively heats and destroys it while sparing the surrounding tissue. This accomplishes the aim with minimal collateral damage. As an example, in laser hair removal, the laser is attracted to melanin which is the chromophore present in the hair follicles, generates enough heat energy and destroys the target.
This heat energy from the laser that is harmful for melanin in the hair follicle can also heat up the melanin pigments in the skin with resultant skin burn. Sciton uses 1064nm long pulsed Nd:YAG as the laser of choice for hair removal. This penetrates several millimeters deep and delivers the heat energy for the intended target of the hair follicle, bypassing the more superficial melanin.
Another interesting feature used in the Sction laser is the method of cooling. Some equipments use a cooling copper plate for pre-cooling and the operator quickly moves and fires the laser at the pre-cooled skin and once again steps backwards with the cooling plate to cool the heated skin. That is a lot of tap dancing with hardly any progress! You can also imagine the operator fatigue working under these conditions. Yet another company uses a spray of cold solution, a cryogen, just before the laser fires, and it sprays again just after. This system also has the potential for injury by possible block of the nozzle or the coolant running dry in the canister.
Sciton has cleverly introduced a technology wherein cold refrigerated fluid passes between two sapphire plates of the scanner which bulk cools the skin deeper and in a non-selective manner. The laser fires through the sapphire plate and hence the skin is protected before, during and after the laser firing . If the tubing that brings the refrigerated fluid gets kinked for some reason, a loud alarm alerts the operator and laser does not fire. You cannot beat that for safety.
If pain is induced in a sequential manner, as in laser hair removal, the nerve endings (neurons) at the skin about to be treated next, will go in a heightened state of alert. This is called ‘neuronal recruiting’ and is the reason for worsening pain as the treatment progresses. The engineers at Sciton came up with a unique solution to address this issue. The built in computer fires the laser through the scanner in a non-sequential manner, thereby not giving a pattern for the brain to anticipate pain. A series of 25 non-sequential shots can be fired precisely with no spaces or overlapping, within a matter of few seconds. No human hands can match this feat!
