Recently I heard getting 300cc high profile looks very natural. Is this true? Thought it was the least natural option

I recommend an in person consultation with a plastic surgeon to discuss your goals and be measured. After I measure and discuss goals with my patients, we then look at pictures of women (my patients) with similar measurements with different size implants. They also get to see what they would look like when the breasts have fully dropped and fluffed and in clothes. You get to see actual results and the surgeon's experience and not a virtual idea of what can be achieved. Women tell me that this process is very helpful in determining what is right for them.

The size and profile is best determined by your measurements and your idea of what size you might like. However, not all women should go as large as they might hope because of their tissue and frame.
Larger implants may need a smaller base, higher profile to fit your breast base.

Higher profile implants do not tend to look natural because they are very projecting (out away from the chest) for a rather narrow base diameter. I tend to place high profile implants in patients that want an "augmented" or "stuck on" or "coconut look". I would recommend a lower profile implant if you are looking for a more natural result; placed below the muscle. I would also recommend finding a surgeon certified by the American Board of Plastic Surgery. I would particularly recommend finding one with excellent experience in breast surgery.
