Intense Pulsed Light

The E-One from E-Swin utilises IPL technology to provide salon quality permanent hair removal in the comfort of your own home, but what exactly is IPL?

IPL or Intense Pulsed Light (as it is more formerly known) describes a light energy that, when applied to the skin, is absorbed by the melanin contained in the hair follicle and is converted into thermal energy. This heat cauterizes the vessel connecting to the base, effectively destroying the hair causing it fall out and never grow again.

IPL uses white light which contains all the wavelengths of visible light from red to blue. However, to concentrate the treatments on different structures, filters are used to reduce certain wavelengths that are not needed.

When trying to destroy the hair follicle heat is essential however, it is also vital that in the process the skin is not damaged. Research has shown that, as the hair is darker, it holds onto the heat generated by the light energy longer than the skin does. Therefore, by giving multiple pulses of light in quick succession, each pulse heats the hair follicle up, along with the surrounding skin but, in the gap between the light pulses, the skin cools faster than the hair follicle. In this way, by using light pulses more heat energy can be transmitted to the hair follicle destroying it, while reducing the heat damage to the surrounding skin. It is this process that gives the term its ‘Pulsed’ nature and it is also this element that makes IPL more effective and less risky than many other treatments including laser.

To ensure 100% safety to the skin, the most important factors to consider include reproducing a uniform light pulse and maintaining the purity of light being emitted. The E-One’s patented technology meets this criteria perfectly - the intensity of light produced remains the same throughout the duration of the flash. This makes it possible to lower the level of light energy emitted, while producing the same quality results as units that emit a higher amount.

The technology used in the E-One hair removal device resembles the same technology found in the flash lamps used by professional hair removal therapists. Recent technological advances have enabled this professional technology to be adopted for home use, meaning it is now possible to obtain professional results in the privacy of your home.
