The basis for IPL treatment is a high-energy light source. This can obliterate the roots of the hair, the so-called follicles, by the right wavelength. This deactivates hair growth. The majority of these hair removers use a broadband spectrum of light for this process. Initially, this type of hair removal was only possible in professional studios. Meanwhile, there is an IPL device for the home.

The abbreviation IPL stands for “Intense Pulse Light” and accordingly indicates the functionality of this type of laser hair remover.

To effectively remove body hairs, first set the energy strength of the IPL device. Simple devices operate with a wavelength between 550 and 950 nanometers. The emitted pulses last between ten and 250 milliseconds. The light does not hit the hair directly but is absorbed by the melanin contained in it and converted into heat. In the hair follicle, this can cause a temperature of up to 70 degrees Celsius. Due to the heat, the protein in the hair is destroyed and the follicle is sclerosed.

Depending on the part of the body where the hair is to be removed, it can take two to ten minutes for complete sclerotherapy. How long you should expose the skin to laser light depends on how sensitive it is. Especially on the face, short treatment phases are recommended to prevent redness.

Keep in mind that a hair removal device is more expensive compared to common methods of hair removal. Therefore, before you buy an IPL device, you should take a look at the advantages and disadvantages of using it:

  • Permanent hair removal with repeated repetition
  • Application on the entire body possible

IPL hair removal is also an option if you want to be hair-free as permanently as possible. If you regularly perform depilatory using laser light, prepare the thermometer you do not have to fear annoying stubble on your legs or under your armpits. Since IPL devices use light pulses to obliterate the hair follicles, the application is painless or completely painless.

Even cheap IPL devices cost significantly more than classic razors or epilators. However, the investment can be worthwhile in the long run. After all, if the hair is permanently removed, you will never need to buy razors, depilatory cream, or other utensils for hair removal again.
