IPL – What Is Intense Pulsed Light?

IPL stands for Intense Pulsed Light. IPL is often confused with laser in hair removal methods. Although IPL and laser are light-based, they are different. 

Laser hair removal uses fixed wavelengths or coherent light to target hair, and IPL uses wide wavelengths or incoherent light to target hair. The difference is that the laser targets specific hair types and skin tones, whereas IPL affects more hair types and skin tones.

With IPL, the light from the device penetrates the skin and hits the hair and hair roots. Light is absorbed by a pigment in hair called melanin. The highest concentration of melanin is found in the hair follicles. ”

The light energy is then converted into heat and damages all hair follicles, including the papillae that the hair produces.

IPL as a laser only works on hair in the anagen growth phase or the first phase of the growth cycle. In the anagen stage, the hair actually grows and lives. 

The hair is still attached to the bulb and follicle. IPL is not directed at the hair in the next two stages because the hair is dead, not attached to the bulb, and has just been removed from the body.

IPL as a laser requires several sessions to be effective because not all hair is in the anagen stage at the same time. It is necessary to repeat the treatment until all the hair in the target area has been treated during the first phase of growth.
