How Does Laser Tattoo Removal Work?

How Does Laser Tattoo Removal Work

Some people need help grasping the concept of laser tattoo removal. But it’s not a miracle; it’s science! While laser tattoo removal is a popular and promising practice, only some patients or doctors grasp the underlying science. The science of laser tattoo removal is outlined in this article, along with an explanation of why this method is the most efficient means of getting rid of unsightly tattoos.

But before we get into the specifics, here are the basics on how getting a tattoo works to understand why removing it is pretty complicated.

How Getting A Tattoo Works

You need to know the process of acquiring a tattoo to comprehend how it is removed. To remove as much tattoo ink as possible from the dermis, the immune system dispatches white blood cells to the tattooed area. The larger particles leave behind the tattoo that the cells cannot digest. Natural fading occurs due to the bigger particles being broken down by these cells over time.

  • Tattoo ink is implanted deep within the dermis layer of skin.
  • Your body’s defense mechanisms attempt to flush out the ink.
  • The motion removes the smaller ink particles, leaving the larger ones behind.

People get tattoos for various reasons, including expressing individuality, showing appreciation, and demonstrating a sense of “cool.” However, the significance of these tattoos may fade over time.

In the past, tattoo removal was unsuccessful, often resulting in painful surgeries and permanent scarring. Lasers have made tattoo removal more comfortable, quicker, and more straightforward. Laser treatments for tattoo removal can break down tattoo ink, and the area where the tattoo formerly was will heal without scarring.

Basics Of Laser Tattoo Removal

In contrast to a laser pointer’s steady stream of light, the light energy used in tattoo removal lasers is delivered in short, intense bursts.

Tattoo ink absorbs each individual energy pulse as it passes through the skin. The tattoo ink particles get hot from the needlepoint and break up into smaller and smaller pieces as they disintegrate. The tattoo’s look is then diminished as the immune system gradually removes the ink particles from the area over the subsequent weeks after treatment. With each treatment under the laser, the tattoo ink is further reduced until it is completely gone.

The Specifics On How Laser Tattoo Removal Works

Typically lasting only a few nanoseconds, the energy pulses generated by pulse laser technology are extremely powerful for their short duration. The mystery of how this brief yet powerful burst of energy can partially explain laser tattoo removal works.

Laser tattoo removal with a pulsed laser is highly effective. Because the particles that makeup tattoo ink are so tiny (usually on the order of nanometers in diameter), they only need to be heated for a brief period before they explode.

Skin cells are much larger and require a higher temperature for longer to be harmed. As a result of the short duration of a laser pulse, tattoo ink can be heated and shattered without harming the surrounding skin tissue. The tattoo ink particles are selectively damaged while the surrounding skin is preserved because of the laser’s short pulse duration.

Targetting The Tattoo Ink

Tattoos can be found in any shade you can think of. In addition, much like everything else in our environment, tattoos absorb and reflect light differently depending on the color. Tattoos seem red because they absorb green light and reflect red light.

Laser tattoo removal relies on the ink absorbing the laser light; thus, selecting a wavelength effectively absorbed by the tattoo is crucial. Once again, using the tattoo as an example, green laser light would be most effective on the red ink because it is the color most readily absorbed by the ink (which makes the ink particles heat up and shatter). The 532 nm laser wavelength is suitable for treating a red tattoo since it appears green to the naked eye.

A wide range of laser wavelengths allows for greater flexibility in treating colorful tattoos. Lasers with wavelengths 1064 nm and 532 nm are widely used for tattoo removal since they can effectively remove 95%+ of tattoos. Some professionals also use 755 nm and 694 nm wavelengths, which are incredibly similar in operation and help treat unusual ink colors like vivid blue and green.

Not An Instant Results

Tattoo removal is a lengthy process that usually requires the patient’s dedication over several months. Typically, a series of 5–10 treatments, each spaced at least six weeks apart, is necessary to remove a tattoo altogether. Tattoo removal patients frequently query the necessity of multiple sessions and the intervals between them. The practitioner who wants to give an enlightening consultation to their patient must be prepared with answers to these questions.

Because not all tattoo ink can be broken up in a single treatment session, laser tattoo removal usually takes several sessions. A tattoo requires many injections of ink into the skin at various depths. The top layers of ink in the dermis absorb the laser light and shatter as it is applied to the skin, but the deeper layers of ink may remain unaffected. Before the deeper layers of ink can be treated, the body must flush away the surface layers. To put it another treatment, the ink will be removed from more profound and deeper layers of skin as you go through the tattoo removal process.

For the body to thoroughly flush away the fragmented tattoo ink from the region of the tattoo, patients must wait between treatments. The ink is carried to the lymph nodes, where the pigments are left behind by phagocytic cells of the immune system as part of the flushing process. To get the most out of each treatment session, you should wait as long as possible in between them because the body can only flush the ink out at a specific speed. Healing any scabs or blisters during this time also reduces the risk of over-treating the area, which could lead to unpleasant side effects.
