![]() Hence, there is usually no need for anaesthetic creams for this procedure.įirstly, the skin is cleansed, eyes covered by protective googles followed by the laser therapy. Most of the patients are tolerable to the discomfort cause by the laser. Black pigments work better compared to other colours.Īpart from these, Q-switched Nd:Yag also produces rejuvenation effect and provides lightening of the skin, which is very much favoured by Asians. Amateur tattoo, those purely black tattoos seems to work better than multicoloured tattoos (professional tattoos). Of course, the machine as well as the operator (the doctor performing the laser) are also key to the results of the treatment.Īnother major indication of Q-switched Nd:Yag laser is for tattoo removal. It is important to get the correct diagnosis at the start to ensure careful selection of treatment modalities. solar lentigo,freckles, lentigines and etc while some produce variable results, i.e. ![]() Some pigmentary disorders work very well with Nd:Yag laser, e.g. However, not all lesions have good results with Q-switched Nd:Yag laser. It can target both superficial and deeper skin pigmentation. Q-switched Nd:Yag laser are used mainly for pigmentary disorders resulting in darker patch/lesions. These damaged cells will then be cleared from the site resulting in lightening of the pigmented site. 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. This means that there is no break in skin tissue continuity during the treatment. It comes in 2 wavelengths, 1064 nm and 532 nm. Nd:Yag laser is named after the laser medium, Neodymium:yytrium-alumunium-garnet. Visible lights are not parallel and does not move temporally in the same phase. Laser waves are parallel to each other and all waves move temporally in the same phase. Laser is basically a type of light that carries only a specific wavelength, as opposed to visible light that carries a range of wavelength. Lets examine what Nd:Yag laser is about in this issue… What is Q-switched Nd:Yag laser?
