Yag laser with nanosecond pulse width is very large, and the relaxation time for the melanin in melanin cells and keratinocytes is short, those small particles (tattoo, melanin) which have preferably absorbed the laser energy will burst instantaneously without having an impact on the surrounding normal tissues. The blasted particles will enter the circulatory system and be excreted out of the body. Basing on the thermal effect of laser, the

treatment for vascular lesion of this Nd Yag laser is to target the abnormally dilated blood vessels with laser and let the hemoglobin absorb the laser energy until it is dead and fall out.

Since Q1064nm laser can be preferably absorbed by melanin and shows strong penetrating ability it is ideal to treat deep skin lesions, like blue and black tattoos, nevus of ota, etc.By contrast, Q532nm laser is mainly used for treating superficial pigmentation disorders, such as freckles,cafe-au-lait spots, and seborrheic keratosis.In addition, a Q532nm laser can be used to remove the red tattoos,lip lines.
