The Basics
The Science
What the laser is actually doing, and why your body does most of the work.
The science behind tattoo removal is stranger than it seems. The laser emits s pulse of light that shatters the ink into pieces but then your immune system kicks in and spends the next several weeks carrying those pieces away. It’s why removal takes months rather than minutes and it’s why two people with the same tattoo can walk out with very different results.
If you read one thing here, make it why some colors are harder to remove. It explains more about your likely outcome than anything else on this site.
Four things decide whether a tattoo comes off
01
Where the ink sits
Your ink lives in the dermis, a layer down from the surface. Anything you rub on top of your skin stays on top of your skin.
02
What color it is
A laser has to be absorbed to do anything at all. Black soaks up almost every wavelength. Yellow shrugs most of them off.
03
How small it breaks
The pulse shatters ink particles into fragments. The smaller those fragments are, the easier your body finds them to move.
04
How well you clear it
Your immune system carries the fragments away over the following weeks. That slow work is what the gap between sessions is for.

It caught us off guard too when we first dug into […]
