ND YAG laser
The YAG (often written Yag) laser is a form of cosmetic laser commonly used for anti-aging skin treatments.
- The YAG laser resurfaces your skin to remove moderate facial wrinkles, surface scars, or splotchy skin discolorations.
- Some, like the GentleYAG, may also be used in vein removal on legs or facial veins.
- YAG lasers have proven effective at destroying the pigment in hair follicles, thus are often used for laser hair removal.
- The YAG laser is considered “non-ablative”, meaning that it does not cut or remove the top layer of your skin; instead, the laser penetrates the skin surface and the energy is absorbed by your skin tissue.
- YAG is an acronym for the components of the crystal: yttrium, aluminum, and garnet.
The ND Yag laser emits infra-red light with a wavelength of around 1640nm. It has two operation modes: pulsed and continuous.
The ND Yag is selective, it only acts on the areas targeted by the laser light and does not damage other skin components.
The YAG laser can be pulsed like the CO2 laser used for facial resurfacing.
- When the laser is pulsing, called “Q-switched,” the laser blasts the damaged or unwanted tissue away. The pulsing should lessen the heat on the skin, therefore reducing potential for damage.
- Some YAG lasers use a cooling spray simultaneously when the laser is heating the skin. One of these lasers is the CoolTouch 1320; it works by spraying the outer skin and sensitive nerve endings with a cooling liquid keeping the skin to 111ºF-118ºF
YAG laser skin resurfacing can help with wrinkles, skin tone and texture, but will not help with excess or sagging skin.
The ND Yag laser gives a very specific result depending on its target.
- It destroys the hair bulb and prevents hair from growing back by targeting the melanin.
- It removes tattoos by targeting the coloured pigments under the skin.
- It smooths mild wrinkles by targeting the superficial layer of the skin.
- It removes varicosities by targeting the blood vessels.
The treatment lasts for between 4 to 6 sessions 1 month apart.
The ND Yag laser results are gradual during the treatment.
