The principle of photorejuvenation and treatment related problems
Photon/IPL is a different term for photon. Photon is a wavelength in the spectrum, such as the photon treatment head 400-720nm for freckle removal, and the vascular treatment head 555-950nm. Of course, there will be some differences between different devices. IPL is the abbreviation of intense pulsed light, and OPT refers to optimized intense pulsed light. At present, most conventional photorejuvenation skins are OPT light sources. DPL refers to optimized intense pulsed light with a wavelength of 500-600nm, mainly for blood vessel problems such as facial redness.
