IPL vs Laser
Laser hair removal is the process of removing unwanted hair by means of exposure to pulses of laser light that destroy the hair follicle. Laser hair removal is one of the most commonly performed cosmetic procedures. Laser hair removal works by beaming a highly concentrated light into hair follicles. Pigment in the follicles absorb the light that destroys the hair.
IPL and lasers work in similar ways by sending light into the hair follicles. The light absorbs in the hair follicle, turns into heat and destroys it. Though IPL is not a laser, it can be compared to one. The main technological difference between the two is that laser uses one specific wavelengths of light, while IPL uses a full spectrum.
This means that unlike lasers, which can only deliver a wavelength, IPL can release light over a wide wavelength range. In short, IPL uses intense light pulses instead of laser rays.
