Yes they certainly can. Both nipples and areolas can be adjusted without doing a more involved breast lift that would give you a vertical or horizontal scar. The only way to know for sure is to book a consultation with a board certified plastic surgeon near you to see what your options are. Best of luck!
Thank you for your questions! I am not sure if you are using the right terms for what you would like to ask but I will try to help! If you feel the nipples (part that protrudes out from the breast) are too large, those can easily be reduced with a small incision in the nipple itself that eventually heals very nicely. If you are concerned about the size or your areola (the flat circular part around the nipple), that can be reduced with just an incision around the areola and would give you a slight lift. I recommend seeing a board certified plastic surgeon in person to discuss your concerns and see what is the right procedure for you!
