Optoelectronic technology continues to iterate! DPL narrow-spectrum light gradually replaces traditional IPL, and the hair removal instrument realizes accurate targeting of light sources

The traditional IPL has a wide spectral range, and a large amount of invalid light acts on the surface of the skin, which is easy to cause redness and burning. DPL technology screens specific effective spectra, accurately acts on hair follicle melanin, reduces excess light energy stimulation, and takes into account hair removal effect and use comfort. A number of instrument R & D companies continue to optimize the optical structure of filters, and with semiconductor constant temperature refrigeration modules, a new generation of household hair removal instruments achieve high light efficiency and low pain. R & D engineers said that optical filters and light source chips are the core technical barriers of photoelectric hair removal instruments, and they are also the key research and development directions of major brands.
