UPDATE: IPL is not actually a laser, but an intense flash of light that is "attracted" to brown and red pigment in the skin. IPL technology has advanced in recent years with BBL (Broad Band Light) overtaking standard IPL by offering quicker improvement and lower risk.Both IPL and BBL target discoloration, but BBL offers a wide range of "color filters" so that most any skin color can be treated safely. Brown Pigment: The absorption of the light causes the brown pigment to shatter, which makes it come to the surface faster. This is why you will see what looks almost like fine coffee grounds on your skin over the next week (or a little longer). They'll naturally slough off. You can make the process easier by keeping your skin moisturized and not picking at the little flakes (Picking at the flakes may cause more problems). You should not experience recovery pain, bleeding or scarring. But you will feel some skin roughness initially and some mottled coloring as the pigment granules fall off. Any "help" should be limited to the light use of a washcloth after your skin is wet, such as after a shower. It's generally helpful to have several IPL/BBL treatments to reach deeper level pigment. Sun screen is required to minimize recurrence. Expect a touch up session every so often if you tend to spend time outside. It's nearly impossible to prevent pigmentation issues in areas with high sun exposure. Redness: The absorption by tiny broken or expanded capillaries shrinks and coagulates them. Larger veins will require Vbeam or other treatment, but the tiny capillaries that cause irregular redness often respond very nicely to IPL alone. It's important to distinguish the cause of pigment irregularities. Melasma needs different treatment than environmentally caused discoloration, so be sure the doctor you see is a board certified dermatologist who can properly determine the best treatment.CAUTIONS:IPL comes in a wide array of "qualities". Cheaper machines tend to carry more risk for loss of pigment, burns and scars. Although widely offered in promotions as a risk-free treatment, in the hands of an improperly trained operator, the results can be anything but risk free. With so many people having a mixed genetic background, it takes a professionally trained and skilled provider to treat your skin safely.
