Nd:Yag laser is named after the laser medium, Neodymium: yytrium-alumunium-garnet. This laser was specifically designed to help with pigmentation, reckless and also can help removing old tattoos.
The Q-switched ND YAG laser takes specific wavelengths light in high energy, which are absorbed by the pigment and shatters the pigment into particles, breaking them into very small fragments, some parts will consequently bounce out of the skin and the other parts will spilt even further into minute particles which eventually will be engulfed by the phagocytes and ultimately gets eliminated by the lymphatic system.
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 are 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.
Q-Switched Nd:YAG is very effective for the removal of dark tattoos and the safest for skin of color. Using a top-hat beam profile ensures control of homogeneous energy delivery and maximum safety without hot-spots nor any risk of side effects or complication for the patient. The versatility of 5 spot sizes allows to use the ideal parameters for the clearance of dark tattoos. Also, there are other functions like the following.
1.Improve skin tone
2.Reduce rosacea and thread facial vein
3.Reduce facial wrinkles and fine lines
