Should I do saline or silicone? Especially what size should I get too? (photo)

Thank you for your question.  As far as size goes, you would need to have an in person consultation.  Given that you are thin, I would recommend silicone implants.  Saline will feel harder and more chance of seeing rippling on someone as thin as you.

It is difficult to say without better photos.  Saline implants are less expensive but may be more palpable and give you a less natural feel if you are thin.  Silicone gels generally feel better and are indicated for thin women, plus the can be shaped like a teardrop and give thin women a more natural look.  The need for a lift also has to be considered depending on whether your breasts have dropped after breastfeeding.  Best wishes, Dr. T.
