Yes I think so, at least progesterone seems to often play a part with breast development stages, usually areolas widen a lot during Tanner stage four, and even more in stage five as that's when a lot of the side branchinh and fullness develops and progesterone is a key component of that. 

This has been my personal experience too. I started prog at around month seven, then bovine ovary at month ten, which probably has similar composition/effect, and that was the time when Tanner four development kicked in and my areolas grew width rapidly. Since then this slowed down but it has taken several growth spurts later on, one of which seems to be happening right now as I'm likely entering early Tanner five development.

I think this is the effect of topical rpogesterone as part of the topical protocol at work. I'm sure Lotus could explain all this from the science stand point in very detailed way, but this is typical effect of progesterone to those who benefit from it. It has some variation for sure, but most trans women seem to get quite a boost from it and areola width is part of that.

So yes, it might do just that.
