[ background ] A method for producing a semiconductor device

With the improvement of living standard, more and more people begin to pay attention to beauty treatment and face care, and the laser depilation instrument is popular with more and more women as a beauty product capable of removing skin and hair. The depilating instrument adopts advanced light depilating technology, effectively prevents the hair of each part of the body from regrowing, and realizes permanent depilation. Light depilation is based on the principle of selective photothermal dynamics, and utilizes the selective photothermal effect of light, and directly irradiates hair follicles by passing light with specific wavelength through epidermis. The melanin of the hair follicle, hair shaft, selectively absorbs light energy, and the resulting thermal effect causes the follicle to necrose, and the hair no longer grows. In the using process of the laser depilation instrument, a user pushes the light emitting end of the laser depilation instrument against the skin and then starts the laser depilation instrument to remove the hair on the skin. Depilation is becoming more and more popular with consumers as a safe, fast and long-lasting depilation technique.
