Best technology for tattoo removal nowadays is the Q Switch laser (aka Q-Switched Nd-Yag Laser).
The treatment is very safe as it just targets the colour pigments underneath your skin directly. The laser energy feels like many tiny hot dots on your skin. Q-Switched Laser Treatment is a more gentle alternative, and requires less sessions than compared to older tattoo removal methods to achieve similar results.
The laser energy effectively breaks down the tattoo ink and removes the tattoo.
