----introduction---- Intense Pulsed Light has become popular over the years in Taiwan. The cost of an IPL session can vary widely in the market. It can range from USD $270 in a clinic up to USD $670 in a major hospital. The goal of "DIY IPL" is to develop a personal product for an individual to benefit right at home. ----characteristics---- IPL is gentler than laser, using wavelength from 420nm ~ 1250nm, that after treatment, users can still go under the sun. Using "cut-off" to eliminate the wavelength that is harmful to the body, the device is designed to select wavelengths to treat simultaneously treat problematic skin conditions. IPL can also breakdown skin pigmentation. The pigments are then absorbed and metabolized and eliminated by the body. This allows purification and clearance of skin back to its clear and pure state.
