There are many differences between lasers and IPL’s. The biggest difference is the wavelength of light. When treating a hair follicle we must ensure the light travels at the correct depth in order to reach the root of the hair. The MedRazor Diode Laser System has a wavelength of 808nm ensuring we reach the root of the hair most effectively. The MedRazor operates by producing a single wavelength (concentrated) which damages the root by selectively heating them while leaving the surrounding tissues unharmed.
IPL (Intense Pulse Light) machines use a broad spectrum of light, sending out multiple wavelengths which are not concentrated, to destroy the hair follicle. This means that not all the light is penetrating at the right depth to target the hair. It opens the body up to receive unneeded wavelengths of energy and damaging multiple structures below the dermis (as shown below). IPL machines do not have the ability to use “selective photothermolysis” which is the rapid heating of a select structure and not the surrounding areas
