There are many lasers in the market. ND Yag Laser is named after the laser medium, Neodymium: yytrium-alumunium-garnet. This laser was specifically designed to help with pigmentation, freckles and also can help removing old tattoos. ND YAG Laser comes in 2 wavelengths, 1064 nm and 532 nm. It is a non-ablative laser, which means that there is no break in skin tissue continuity during the treatment. It is designed to target pigment cells. This specific wavelength is absorbed preferentially by pigments (melanin) and the resultant heat will cause generation and propagation of waves that cause damage to the cells containing pigment. These damaged cells will then be cleared from the site resulting in lightening of the pigmented site.
Skin tags are a common nuisance on many people and can become increasingly irritating as time goes on. They appear as tiny pearl drops attached to the skin’s surface and tend to multiply in aging skin. Skin tags can appear on almost any part of the body and vary in appearance from person to person. They can be tiny or grow very large and irritated due to rubbing on clothing or other skin surfaces. While skin tags are not particularly dangerous, they become a problem when they are larger and more susceptible to being torn. They are also irritated when people don’t realize they are shaving over them. This will not remove the skin tag, only irritate the top layer causing a scab to form. Many individuals who choose to remove skin tags also do so for cosmetic purposes. The choice of treatment for skin tags and moles is highly dependent on the size, depth, appearance, and location of the lesion. These lesions respond to lasers, as the lasers emit one specific wavelength of energy which travels into the lesion to a specified depth and cause the lesion to contract/shrink.
