What causes some breast implants to look fake while some others look very natural?

Bigger breast implants look more fake. Highly projecting implants look more fake. Using implants that are bigger than what the soft tissue can handle (measurements) makes one look fake. Best wishes, Dr. Aldo

When the surgeon places a breast implant partially behind the chest muscle (this is known as the dual plane), the rim of the implant is blunted. This adds to a more natural look. When the implant is placed in front of the muscle, it will have more of the tell-tale tennis ball look. For more information on this and similar topics, I recommend a plastic surgery Q&A book like "The Scoop On Breasts: A Plastic Surgeon Busts the Myths."

There are a couple reasons that breast augmentation can look fake vs. natural. First is the location that the implant is placed.  Implants placed in the "dual plane" position under the muscle tend to appear more natural than implants placed in the "subglandular" position on top of the muscle. Second is size.  Generally speaking, the larger the implant size (especially when the implant diameter is much larger than the native breast width) the less natural the breasts will appear. In response to your postulation about aftercare by the patient, I can tell you that has little if anything to do with the results a woman will have after her breast augmentation. Best of luck to you!

Everyone has a different goal in mind when doing a breast augmentation.  Some women want the larger, "fake" look and some a smaller more natural look.  The size, profile, and shape of the implant is based on your desired breast size/shape, your chest wall measurements, and your existing soft tissue.  The decision of which implants to use should be based on a detailed discussion with equal input from both the doctor and the patient.  A good surgeon will work with you to help you achieve your goals.

Hello and thank you for your question.  The end result of a breast augmentation is influenced by a number of factors.   The size, profile, and shape of the
implant is based on your desired breast size/shape, your chest wall
measurements, and soft tissue quality.  This decision should
be based on a detailed discussion with equal input from both you
and your surgeon.  My ultimate goal is a natural shape, without a fake look.  Make sure you
specifically look at before and after pictures of real patients who have
had this surgery performed by your surgeon and evaluate their results.   The most important aspect is to find a
surgeon you are comfortable with. I recommend that you seek consultation with a
qualified board-certified plastic surgeon who can evaluate you in person.
Best wishes and good luck.

There is a lot that goes into a breast augmentation - much more than most people realize.  It is a marriage between the patient's goals and what realistically will fit well with their frame, breast tissue, and measurements.  For those of us that do a lot of these surgeries, it is much more of a mathematical game then simply shoving something in arbitrarily.  Unfortunately, there are surgeons out there that do not follow the right principles which can then lead to issues over time.  Post operative pictures from a surgeon are always a good indicator of their work.  If you find a surgeon whose patients all look very round and fake, then that is an indication of how they do their surgeries.  The best thing to do is to go for a few consultations with board certified plastic surgeons and see what they recommend.  I hope this helps.
