Tattoos are more popular these days. Along with more tattoos, there are people who want to get rid of the tattoos. Long time ago, these tattoos were removed by hot iron, sand paper, and skin grafting! Thankfully, we now have laser tattoo removal, which hurts much less. Specially with the new picosecond laser, tattoo removal has become more effective.
For those who want a good investment opportunity, I suggest looking into Cutera who patented the Enlighten laser for tattoo removal (I have invested in Cutera). Roughly 25 percent of Americans aged 25-40 have tattoos and many will consider removing them. Plus, they will be more likely to remove knowing that some tattoo inks contain toxic chemicals.
