Im pretty sure scars arent in the nipple, so I dont think she photoshops them for such.
Plus if a scar is anywhere else other than on plain skin, even photoshop wont hide it.
Do they still do implants through the armpit or navel? Seems like that would be a better route for her size.
But hiding the nipples til now and the blurring is very weird if there wasn't scaring. I can't imagine it would be anything like general swelling, discoloration or "settling".
