Laser tattoo removal happens in phases because ink is placed at different depths in the dermis. Each session targets the most accessible ink first; the deeper ink is treated in subsequent sessions. The immune system takes time to clear broken-down pigments. Giving skin time to heal between sessions helps recovery and lowers the risk of complications.
Most clients need between 6 and 12 sessions, depending on tattoo age, colour, location, ink density, and individual immune response.
