For the regulated Level 5 tattoo-removal qualification, yes. Level 4 laser (or equivalent clinical laser experience) is the entry requirement, on top of Core of Knowledge. The progression is deliberate, because tattoo removal’s Q-switched physics and complication profile assume you already understand lasers. Weekend ‘tattoo removal diplomas’ for beginners skip that for a reason.
The Level 3 → Level 4 → Level 5 ladder frustrates people in a hurry, but it maps real risk. Q-switched and picosecond devices deliver nanosecond pulses at fluences that shatter ink, and skin too if parameters or patient selection are wrong. Our Level 5 page publishes the full ladder with honest total costs and timescales from any starting point, because deciding with real numbers beats discovering prerequisites after you’ve paid for the wrong course.
