The ND YAG laser is the most commonly used device for tattoo removal. The adjustment of treatment parameters allows the user to customize the treatment to the individual patient’s condition and skin type to maximize results and manage patient comfort and reduce potential side effects. The highly selective endogenous melanin of Q-Switched lasers performs as a high-speed shutter.The laser rods store energy in high quantity and emits them efficiently on the most affected areas of the skin. The high-speed pulses have to exit on the affected areas to heal the skin from internally. In nanoseconds are pulses are emitted and the bean stays uniform to avoid any harmful effect.
