Intense Pulsed Light (IPL), as most commonly employed by non-specialist
medical practitioners and beauticians, is a method of hair removal from
the body involving the use of a specially constructed xenon flash lamp
and focusing optics. The Intense Pulsed Light hair removal process has become very popular due to its cheaper and faster procedure compared to laser hair removal, which is often more costly and time consuming. The comparison of effectiveness between Intense Pulsed Light and Laser Epilation is debated by scientists, equipment manufacturers and practitioners but is generally accepted to be equivalent results. IPL is generally advertised as "permanent hair reduction" as opposed to "permanent hair removal" (these phrases are misnomers when applied to laser or IPL hair removal). Hair removal mechanics: The focused, broad-spectrum light is applied to the surface of the skin by way of either a hand-held wand, or by an articulated arm. The intense light travels through the tissue of the skin until it strikes the hair shafts or the bulb (root) of the hair. The bulb is usually where the highest concentration of melanin is located, as opposed to the rest of the hair shaft. The light is converted to heat energy. The bulb and most of the hair shaft are instantly vaporized. The intense heat radiated by the hair also destroys the hair-producing papilla or the entire hair follicle. It is also claimed that direct light-heat conversion occurs directly in the darker colored capilaries that bring nourishing blood to the follicle. IPL technology is also employed in the treatment of medical disorders of the skin including sun damage induced dyspigmentation and vascular changes; poikiloderma of Civatte; acne Rosacea; broken capillaries/telangiectases; vascular and pigmented birth marks. In terms of rosacea, IPL offers one of the few effective treatments to relieve the facial redness associated with the disorder. Such treatment is best administered by a specialist dermatologist. This new technology incorporates 'dual mode filtering' and other important advances which result in safer and more effective treatment than the older systems; which were initially designed for simple processes such as hair removal. The pulses of light produced by IPL equipment are very short in duration, so discomfort and damage to non-target tissues is minor. Most people who undergo IPL epilation only experience slight irritation similar to that of a minor sunburn though under certain circumstances, blisters may occur. Men undergoing the procedure experience greater discomfort as male body hair is generally thicker than women's. Depending on the instrument settings and intensity, treating sensitive areas such as the chest and face can result in pain comparable to waxing the same areas; however this pain dissipates immediately. The light that emanates from the IPL wand is filtered to remove any ultraviolet components, eliminating the possibility of UV skin damage.

Tattoos are the result of pigments that were inserted into the skin and stay there. The energy of the light pulse is absorbed in the pigments of the tattoo, shakes the connections between the pigment molecules and gradually breaks the big constructions into small ones. When a piece is small enough to pass throw the cells membrane it is treated by the cytoplasm as waste, driven out of the cell and dissolves in the blood stream. |
