I've been doing a lot of research since you're the second person to comment on the punch size. Seeing some of your posts, I know you know a good amount about F.U.E and probably know that some F.U.E. Surgeons do punch sizes up to 1mm. In fact, .9mm is currently fairly standard for F.U.E. procedures; besides creating larger scars, larger punches can risk collateral damage to neighboring follicles. Smaller punches risk transecting the follicle structure, or not bringing enough scalp tissue along that will allow the follicle to survive. I do see a lot of pictures with people with smaller punches like yours that heal quicker but, that's not always the best options for surgeons and there overall needs to be compromises to achieve the results you want. I personally don't mind the punch size as long as it heals well; which, I am fortunate enough to have a lot of dermatologists' and aestheticians' as clients to know what to do and how to heal it even better then most would (Thank god for being a hairstylist!). I've also, seen other before and after photos of Dr. Panine with the same punch size (.7mm) and they had pretty great recovering results and overall even better hair results.
So, please don't be alarmed because all procedures are done differently and all overall healing results are different depending on the person.
