Dalhousie student, develops tattoo removal cream

Nowhere near to market yet, but if it happens this gentleman will become very very rich. And owners of "unfortunate" tattoos will be very very grateful.

During tattooing, ink is injected into the skin. The ink initiates an immune response, and cells called “macrophages” move into the area and “eat up” the ink.

The macrophages carry some of the ink to the body’s lymph nodes. But some of those macrophages that are filled with ink stay put, embedded in the skin. That’s what makes the tattoo visible under the skin.

Falkenham’s topical cream works by targeting the macrophages that have remained at the site of the tattoo. New macrophages move in to consume the previously pigment-filled macrophages and then migrate to the lymph nodes, eventually taking all the dye with them.
