What is the wavelength range of IPL?

200-800 nm
300-900 nm
400-1200 nm
500-1500 nm

The correct answer is: 400-1200 nm

The wavelength range of Intense Pulsed Light (IPL) typically spans from 400 to 1200 nanometers (nm). This range allows IPL devices to target a variety of skin conditions and hair types, as it encompasses visible light and a portion of the infrared spectrum. The lower end of the range (400 nm) covers the visible light spectrum, which is effective for treating superficial skin issues, while the upper range (up to 1200 nm) helps to penetrate deeper into the skin to address various hair removal needs. The versatility of this wavelength range is what makes IPL a popular choice in aesthetic treatments, facilitating multiple applications beyond just hair removal.
