There will always be doubters who question the sincerity of one's transformation. I do think that there are doubters in Paul's time who question his radical transformation. I too have some lingering doubt over Ms. White's transformation.

However, the tattoo removals and removal of plastic surgery does give credit to her sincerity since I seriously doubt that removals like that are cheap nor easy to endure. After all, people have died during plastic surgery and I do think that removal of plastic surgery is equally dangerous.
