IPL (Intense Pulsed Light) is a kind of light with high energy and broad wavelength, within the range from **0nm to ***0nm. Intense Pulsed Light with broad spectrum affects pigmentations, vascular lesions and hair follicles. Photothermic and photochemical action will be triggered by the radiation of IPL. Pigment is shattered and eliminated out of body through metabolism. Meanwhile, IPL will also promote collagen production, which can make the skin more flexible and smooth. The light with long wavelength can easily pass through epidermis layer to the hair follicles in the deep skin layer. At the targeted area, high energy occurs to destroy follicles and hair shaft, preventing regrowth of new hair. With a series of treatment, IPL technology can help restore a more youthful appearance without downtime and side effect.
