Is there a procedure to make my areolas bigger?

Not specifically: The areola often grows in proportion to the rest of the breast. Gaining weight, breast growth, or augmentation, may enlarge your areola. A color matched tattoo may also create the appearance of an enlarged areola.

Yes: Breast augmentation alone may often result in dilatation or enlargement of the areola. One may also excise skin around the areola with closure causing stretching and enlargement of the areola. More commonly the areola is reduced. See a local bd. Cert. Plastic surgeon for more details.
