Hi Daisy. The answer is yes and no. When a tattoo is placed in your skin, the ink particles are a large size such that they cannot be metabolized (or passed out of your system as you put it).Laser treatments use light, which is transferred into heat when the light hits the ink particles of the tattoo. Together the light and heat break apart the larger ink particles into smaller ones that can then be removed and carried away by the body. So part of the answer is that without a laser, the tattoo will not likely go away on it's own because the ink particles are too large to be removed.If you then move on to a different questions....does Picosure work faster than other lasers...the answer is again maybe and maybe not. If you are treating light blue (aqua) or green color, the Picosure works great and faster than probably any other laser. But if you are treating black or red, then it's not as good at getting rid of the ink as a traditional q-switched Nd:Yg laser. The reason is that each type of light reacts with tattoo colors differently. And the type of light in a Picosure (Alexandrite 755 laser light) is not as highly absorbed in red or black as the Yag wavelengths (532 and 1064).So, a Picosure is better than no laser at all, but how quickly it will remove the tattoo vs. other lasers depends on what colors you are trying to treat. Hope this answers your questions and good luck.
