In hair removal procedures, Abstract a laser device is used at a lower output power in individeals with relatively large melanin content : Asian races. The device (Light Sheer (R) Coherent Medical, USA) using the semiconductor diode pumped laser may be useful for Asian patients since the device is equipped with the Chill Tip (R), a cooling device, on the tip. We evaluated the effectiveness of the device in this study. We examined the hair bearing areas of dermal tissue surgically removed for benign tumor. The level of poower output used in this examination were 20J, 25J, 30J/cm2. The each power level was applied either with or without the Chill Tip(R). We examined the treated areas by video microscope. In addition, the tissues were examined with light microscopy. Noted with those treated with 30J/cm2 the epidermal and dermal damages were rare for tissue using the Chill Tip (R). With the Clill Tip (R) turned OFF, it showed epidermal damage even at 20J/cm2 output level. We conclude that the laser device with the Chill Tip (R) cooling device can avoid shortcomings of other lasers which have no cooling devices for hair removal thus enables us to provide patients with an effective treatment. The video-microscope was useful in checking the maginitude of epidermal damage. Key Words : hair removal, diode laser, skin cooling, video-microscope, Asian races
