▶ Previous Artlcle : #17-1. IPL(Intense Pulsed Light)
At that time, IPL in the spotlight appeared to lose attention with time unlike laser, but it was the wrong idea.
On the contrary, IPL machines have currently become the equipment fundamentally required to aesthetic clinics, and further, IPL is creating another new boom in the field of ophthalmology as its therapeutic effect on xerophthalmia has been demonstrated in recent years.

Properties and Configuration of IPL
IPL is quite different from laser, but when explained to the general public, IPL is not separated from laser for their better understanding because it has similar effects and releases light like laser.
However, specialists in aesthetic medicine should be well acquainted with the differences between laser and IPL.
As you know well, laser is characterized by monochromaticity, coherence, collimation, and high intensity, whereas IPL has the general properties of light such as polychromaticity, incoherence, divergence, and low intensity since it adjusts only the wavelength range through the optical cut-off filter while using the light of the xenon flash lamp as it is.
In particular, the different wavelengths due to polychromaticity can be applied to multiple chromophores through the optical cut-off filter.
Therefore, IPL is variously indicated for the treatment of pigment lesions and vascular lesions, hair removal, skin rejuvenation, sterilization, and the reduction of inflammation.
