Shattering the Ink
How tattoo removal works is 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.
