IPL stands for Intense Pulsed Light and is not a laser. IPL has multiple wavelengths (non-coherent light). Laser is one wavelength (coherent light). For purposes of hair removal, the diode laser is the gold standard. At Entre Nous Aesthetics, we use the Lumenis Light Sheer diode laser. While IPL can be effective for hair removal, in our experienced hands, we have found that laser is more effective for hair removal.
