There are many factors to consider when considering breast augmentation. These include a patient's goals, pre-op size, degree of ptosis (sag), symmetry/asymmetry, chest anatomy, and tissue quality. Beyond these augmentation specific factors, candidates for elective surgery should be healthy and have reached a stable weight to ensure a good outcome. Augmentation candidates should also give some consideration to future plans for pregnancy/breastfeeding as this may compromise results. Based on your photos alone, you appear to be a reasonable candidate for augmentation (minimal asymmetry/minimal ptosis). However, there is no replacement for an in-person exam. With regards to your specific questions: -There are a few major implant brands with similar offerings. They are, for the most part, interchangeable. -Gummy bear and tear drop are marketing terms and do not refer to anything specific. Most 5th generation implants are cohesive gels with "gummy bears" representing the stiffest along this continuum. -Shaped implants i.e. "tear drop" have fallen f favor as texture has become increasingly unpopular. Texture helps an implant maintain its orientation. This is most important for a shaped device. However, as surgeons have moved away from texture so to have they moved away from shaped implants. -Initial recovery time is 7-10 days with full healing by 6-8 weeks and a final result by 6 months -Choosing a provider is a complicated question which cannot be simply answered. At the very least ensure that your surgeon is ABPS certified and is operating in a AAAA certified facility. As always, discuss you concerns and goals with a board certified plastic surgeon (ABPS).
