Intense Pulse Light(“IPL”) used broad spectrum of white light and with filters to marrow the spectrum to target specific chromophores and structures. IPL is a non-invasive skin treatment that emits powerful bursts of light energy to treat unwanted hair, sun damaged skin, and wrinkles, etc. without damaging the surface of your skin, IPL systems use flash xenon lamps to emit micro pulses of light across a broad band of visible wavelengths. IPL work by using particular wavelengths of light that is called by melanin which colors the hair and brown skin and black. Since melanin absorbs light to be warm or hot, that the production of cells called melanocytes and melanin are denatured more produce more melanin. By using gentle pulses of light momentarily to create heat, IPL can permanently disable hair follicles, preventing hair follicles` future growth. The melanin in the hair (which gives it its color) absorbs the light, which is then converted into heat. This heat is transferred to the growth cells surrounding the root of the hair, disabling them. By the IPL, pigments are Shattered and eliminated out of body via metabolism. At the same time, IPL also helps increase collagen production, which rejuvenates the skin leading to a more youthful, radiant, bright and few fine wrinkle skin. The light with long wavelength can pass through epidermis to the hair follicles deep underneath the skin. At the targeted area, IPL occurs heating to destroy follicles and hair structures leading to permanent hair removal.
