The tattoo removal business is huge, generating around $75 million in the US alone. Laser ablation is the most common removal method, but now a 27-year-old PhD student in Canada has come up with a cream that promises a gentler, safer method to get rid of undesired tattoos.
Developed by Alec Falkenham, a PhD student in Pathology at Dalhousie University, the new removal solution is called Bisphosphonate Liposomal Tattoo Removal (BLTR).
The inspiration came from the body's immune system and its reaction to tattoo ink. It involves the macrophages, white blood cells that eat foreign material to protect surrounding tissue from invaders. Known as the big eaters of the immune system, they consume the tattoo ink that settles into the skin.
