Breast implants have been around for 50 years. While originally made popular by Las Vegas dancers, now the typical patient is a mother whose breasts have changed after pregnancy and breastfeeding.
The most popular implant currently is gel implants (which look and feel more natural than the saline version).
Small-breasted personalities like Kate Hudson and Nichole Richie have opted for an implant that reflects a more natural look. However, the important part of the equation in breast augmentation is to see a plastic surgeon like Dr. Jack Peterson in Topeka, that listens to what the patient is looking for and custom fits the implant to their body size and desired size results.
