Yeah, definitely wait at least 18 months to 2 years; it took me 2 years to see the final results b/c I had a LOT of swelling. But then I was really, really pleased. I didn't even take advantage of the free revisions, b/c I was already satisfied with the outcome at a year, and then it kept getting better.
Heck, I had a gynecologist examine me without knowing and end up writing a note for insurance purposes that said I was a cis woman who'd had a hysterectomy.

(I had to go back to her and out myself and get her to fix it, sigh...)
And I went to Brassard, so I'm living proof that at least *sometimes* he produces results which will pass muster even with the experts. I don't know how often that happens, but my impression is actually that he's very consistent.
