Raw files, Topaz and Lightroom

So I’m a brand new Topaz Denoise AI user. The articles I’m reading say that the workflow should be first Topaz and then Lightroom. I understand that when I manipulate a raw image in Topaz I need to save it in another format like TIFF. Which means that when I bring that image back into Lightroom it is not Raw. Won’t this impact the rest of my Lightroom post processing, not being Raw?

What am I not getting?

Thanks!

Read this article … the TIF from LR can still be processed non-destructivly
