Q switched Nd yag laser is a high-powered laser that removes unwanted tattoos and pigmented lesions (sun spots, freckles, etc.) It emits a highly focused beam of laser light, which passes harmlessly through the outer layer of the skin and is absorbed primarily by the tattoo ink or the excess pigment within the lesion. lt also tightens the collagen which improves certain types of rhytides (wrinkles) and other signs of photo damage (Sun damage).
As the light is absorbed, it is quickly converted to heat. The sudden rise in temperature within the treatment target tractures the ink or pigment into tiny particles. Tattoo ink tragments are carried away by the lymphatic system, while pigmented lesions are naturally shed from the skin one to two weeks after treatment.
A wide range of pigmented lesions can be treated, including Nevus of OTA, cafe-au-lait spots, Beckers Nevus, Melasma, Peutz-jegher’s spots, certain types of scars, Lentigines, freckles, sunspots and many brown colored birthmarks.
A tattoo’s color, depth, and the chemical composition of the ink all affect how it responds to laser light.Black, red, dark orange, and dark blue tattoos will usually respond relatively quickly to treatments with the QSYL.. However, green, purple, brown, light orange, and light blue colors may require more treatments. In general, most tattoos can be successfully treated, given a sufficient number of treatments.This laser is also used for reducing certain types of scars and wrinkles.
Since the laser light selectively targets the undesired ink or pigment, other tissues remain largely unaffected, and theretore most patients report little discomfort. Many people compare the sensation of the pulses entering the skin to the snap of a rubber band. if such “snaps” are too uncomfortable , your physician may offer you local anesthesia, but this is usually not necessary.
Immediately after laser exposure, the treated areas may become whitish-colored and swell slightly. This whiteness subsides in about 30 minutes.The swelling may last longer, but can be reduced by cooling the skin with an ice pack. The tattoo or pigmented lesion will fade over the next few weeks.
Depending on the size and location of the tattoo or lesion, each treatment usually takes about 10 to 30 minutes. Some faint tattoos and pigmented lesions will fade completely after only one treatment, though most may require five treatments or more. Treatments are spaced six to eight weeks apart to give your body sufficient time to fully eliminate loosened particles of ink or pigment.
Side Effects are rare. When side effects do occur, they are usually mild and confined to the treatment target.
The alternatives for pigmented lesion removal vary, depending on the nature of the lesion.In the case of tattoo removal, however, laser treatment is the only effective method that is unlikely to cause any scarring, The alternatives to laser tattoo and pigmented lesion removal include surgical excision, salabration (using salt to burn away layers of skin), and chemical peels (using acid to burn away layers of skin). These methods not only cause scars, but can also be painful.
