Is the R20 method a safe and effective way to remove tattoos?

Hi! I'm in the process of getting a tattoo removed at a clinic that uses the PicoWay laser. I've had four sessions so far with okay results. I recently came across the R20 method, and I've seen mixed reviews. Some clinics and reviews say it removes the tattoo much faster, other say it's a scam as your body needs the time in between each session (or pass) to effectively clear the ink and heal. Hoping you can provide some more insight. Thanks!
