How Laser Tattoo Removal Works
Advanced Technology Meets Smart Skincare
Laser tattoo removal is a popular cosmetic procedure that is safe, effective, and only takes only minutes to perform.
Have you ever seen an old tattoo that is partially faded? Tattoos naturally fade over time because the body’s immune system recognizes that tattoo ink is a foreign substance and tries to remove ink particles.
Laser tattoo removal speeds up the natural process by shattering tattoo ink into smaller pieces that flush away more easily.
Tattoo Ink and Skin
Tattoo ink is trapped in the deepest layer of the skin. When tattoos are applied, ink particles are inserted with a needle into varying depths of this bottom layer.
When tattoo removal laser light is applied to the skin, it heats up and shatters the ink that it reaches first within the skin. In other words, the shallowest layers of ink are removed before the deepest layers.
It takes multiple treatments to penetrate through all of the varying depths of ink in a tattoo. If a tattoo is particularly dark or bold, it will require more treatments to remove the ink compared to shaded tattoos with a lower density of ink.
Shattering the Ink
Tattoo removal is an advanced procedure because tattoo ink needs to be heated at very high temperatures to shatter, yet high temperatures usually cause skin to scar. Astanza laser systems feature a sophisticated technology, Q-switching, that effectively breaks down ink without scarring.
Astanza Q-switched laser systems feature amazingly short laser pulses that only last for nanoseconds (billionths of a second).
Because the laser pulse is so brief, the power is high enough to shatter the ink. But, because the energy is in the skin for such a short period of time, there is no risk of damage to the skin.
