How does a Q-switched laser work in tattoo removal?

A Q-switched laser is specifically designed to deliver short, high-energy pulses of light rather than continuous energy. This pulsing mechanism is crucial for its effectiveness in tattoo removal. When the Q-switched laser is directed at the tattoo, the intense energy of the laser pulse is absorbed by the ink particles in the tattoo. Due to this absorption, the ink particles heat up rapidly and then break apart into smaller fragments.

These smaller fragments can then be more easily absorbed and eliminated by the body's immune system. The short duration of the laser pulse minimizes heat transfer to the surrounding skin, helping to protect the skin and reduce the likelihood of damage. This method is particularly effective for a variety of ink colors, as different wavelengths of light can target different inks. By breaking the ink down into smaller particles, the Q-switched laser provides a targeted and efficient approach to tattoo removal.
