< P> 1, the laser wavelength of beautiful < / P>
< P> laser to remove hair must meet two important conditions, : laser can fully absorbed by the hair follicle tissue; Second, the laser can effectively through the skin to the hair follicle. Long pulse laser wavelength of 1064 nm, in the near infrared region of the spectrum, melanin absorption is better, at the same time, deep can penetrate to the dermis and subcutaneous adipose tissue, apply to different area and depth of the hair follicle, remove any part of the human body and the depth of hair. < / P>
< P> for the leg veins and capillaries expansion, problems such as the target tissue Oxyhemoglobin, using selective absorption of the target tissue, long pulse laser by using the principle of pulse width is wide, that in the thermal buffer effect time to achieve the purpose of operating target tissue. < / P>

Such as the scalp, beard, upper lip hair growing cycle respectively is 85%, the proportion of 70%, 65%. And armpit hair, bikini, chest growth period accounted for only 30%, arm, leg hair growing up in the proportion of small, only accounts for 20%.
