Uneven areola & areola too big after reduction, is there anything I can do? (Photos)

I think your surgeon did a great job with your reduction. You can always have your nipples downsized, but it is hard to predict how much they will stretch out after a revision, for the position of the nipples you would likely need to reduce the distance from the nipple to the fold under the breast on that side. The other side may need a similar procedure to have that done, it is hard to tell based on pictures exactly what would fix the things that bother you but there are definitely options

Dear rhuttonnnn,
From the photos, it certainly does not appear that you have a 1 cm difference in your areolar diameters. It also appears that the second bikini cup is pulled more laterally than the right. Regardless, your areolae can always be furthered reduced in size. Return to your surgeon for options. Good luck!
