Tattoo ink is injected under the skin, into the dermis (the thick layer of living tissue below the epidermis) where it is less accessible. The larger the ink particle size, the more difficult it is to remove. Traditional laser treatments break up ink particles to make it easier for the body to get rid of them, but after multiple treatments, the ink particles may still be too large for the body to eliminate.

Darker skin tones are more difficult to treat with traditional lasers because more of the energy is absorbed into the skin rather than the ink particles. This increases the risk involved in treating individuals with darker skin. The Pico laser targets light at colours matching a specific laser wavelength in picosecond pulses that shatter tattoo ink into tiny particles. The body can easily remove these particles through natural processes. The Picolaser emits less heat energy than traditional lasers, which makes it a safer, more comfortable treatment with fewer side effects for patients, including those with darker skin tones.
