If you have excess body fat, why not have a consultation with a fat-transfer specialist like Dr. Bednar? You'll get accelerated results, body-contouring from liposuction, and you won't spend months or more being disappointed, wasting money, and potentially harming yourself with various treatments. Based on the widespread poor results I've seen on this forum over the years, especially in post-parous women with significant involution, surgery is the only reasonable solution. Join Dr. Bednar's Facebook group and look at the before and after pictures, then compare those results with the results in the personal programs section of this site, and see which one is more appealing to you.
Imagine how long it would take, and how unlikely it is, for a topical or oral preparation to build several hundred milliliters of pure fat strictly in the breasts, as can be done with a fat-transfer procedure. And the hormonal changes necessary to restore the involuted glandular tissue would cause systemic issues that would make that treatment unsustainable. Moreover, not only does the procedure give you full breasts, but you get permanent removal of fat cells from obnoxious areas of the body.
