First of all, not ALL areolas do bulge out naturally... some, viewed in profile fit exactly within the curvature of the breast itself and others DO protrude to one degree or another (often called puffies... I happen to like them tho' some folks don't). Other times, the areola might not actually bulge at all, but because of it's large diameter it appears to be sort of a puffy if the breast itself comes to some sort of a well-defined point. In any case, though I don't know much about 'areola implants' I see no reason why that would be any different than pectoral implants for men: smaller, solid silicone (not liquid in a bag) that are placed to provide the definition desired. IMHO, nipples are as crucial to overall breast appeal as the size/shape of the breast itself is... I personally think that I'd probably prefer non-augmented nipples, but not having actually had any first-hand experience with augmented ones, I can't say that with 100% certainty.
