How Does Laser Tattoo Removal Work?

So how does laser tattoo removal work? To understand this, you need to know how the artist puts ink on the second layer of your skin (called the dermis) in the first place. The ink of tattoos contains metallic compounds such as copper, manganese, and lead. Red ink even contains mercury. Don’t worry, it’s not dangerous like ingesting these compounds would be, but there are risks involved.Tattoo ink layers

Risks aside, these metals are responsible for making the ink latch permanently (more or less) on to your skin. When the needle deposits the ink on your skin, the immune system gets to work because it recognizes the ink as an intruder. This reaction is why the white blood cells do its best to bring these particles to the liver. The liver’s job is to eliminate waste from the body, after all.

However, because most ink particles are larger than the white blood cells, they remain on your skin despite fading over time. In order to erase a tattoo, you will need the help of lasers to facilitate the cracking of ink particles. This cracking makes ink particles smaller and allows for the removal from the body.  Because the lasers break up the ink particles into smaller sizes than the white blood cells, these cells can (at long last) take the smaller ink particles to the liver. And from here, the liver expels the ink particles from the body.

So How Does The Laser Work?

Laser tattoo removal has come a long way in just a few short years. There are two main types of laser tattoo removal procedures: PicoSure and Q-switched Nd:YAG.

Traditional  tattoo removal is still being done with the Nd-YAG.  The Nd-YAG works using a process called photothermolysis and is the same process used in laser hair removal.These lasers are not only immensely fast, but also very hot and work with small frequency waves of light. Two of the most important aspects of laser removal are the heat and the speed of the device to break up the ink particles. For an ink particle to crack, it needs to be heated so that it expands due to thermal expansion. However, this has to be very fast to make sure that parts of the tattoo remain cool. The contrast in cool and hot temperatures is responsible for cracking the particles.

The Gold Standard In Tattoo Removal 

The latest development in tattoo removal lasers is the Picosure™ from Cynosure.

PicoSure lasers deliver rapid pulses in picoseconds—literally, a trillionth of a second—to the tattooed area to break up the small tattoo ink particles. While traditional Q-switched lasers deliver photo-thermal pulses that heat the skin and surrounding tissues, PicoSure uses photomechanical technology to shatter the tattoo particles.

PicoSure patients report shorter recovery time compared to Q-switched lasers and fewer treatments to remove the tattoo. PicoSure laser tattoo removal can even remove stubborn blue and green ink and can be used in areas that have already been laser treated.

If you’re looking for the safest, most effective way to remove your tattoo, PicoSure laser tattoo removal is the industry standard. Call London Laser today to schedule your free tattoo removal consultation.
