Derma T|R

How does the Derma Q-Switched Laser work?

The word ‘laser’ is an acronym for ‘Light Amplification by Stimulated Emission of Radiation.’ Lasers are monochromatic, which means that photons emitted will be moving at a wavelength (for example colour) determined by the gain medium. They are also collimated, meaning that in a vacuum, the light beam won’t spread out.

Lasers fall into various classifications, dependent on the power emitted, varying from Class I to Class IV. Most lasers used in aesthetics and all lasers for tattoo removal are Class IV, meaning they are the most powerful class of laser, and goggles or patient eye shields are required to be worn for safe use of the device.

There are two elements that make T|R Q-Switched lasers essential for treating skin conditions:

• The 1064 nm and 532 nm wavelengths can be useful for targeting certain pigments
• The pulse is powerful enough to destroy its target, but brief enough to not harm the skin

T|R Q-Switched lasers are used for much more than just tattoo removal, they can be used to treat pigmented and vascular lesions, non-ablative skin resurfacing procedures, as well as toenail fungus. With all of these applications, wavelength selection is critical in treating the problem as efficiently and appropriately as possible.
