What will work for saggy breasts?

In the past 15 years or so, there have been a few doctors who showed some slight breast lifting when the controversial breast liposuction was done, and others have wondered if radiofrequency or ultrasound energies would lift breast tissue. Remembering that Ultherapy ultrasound is focused and not the same as non-painful ultrasound used for diagnostic purposes.  What is not known yet is how safe these energies would be on breast tissue. If the shallow 1.5 mm transducer of Ultherapy were used on the skin of the breasts it wouldn't penetrate into the glandular breast tissue but the effectiveness and safety of this, still, has not been investigated.

There are currently some studies in progress which are evaluating Ultherapy's ability to provide a subtle breast lift. These results if any will be minimal at best. Surgery still remains the gold standard for breast lifting.

Ultherapy can be used to treat the face, neck and upper chest.  It is not approved for use on the breasts and I have not heard of it being used to treat that area.  I am also not aware of any non-surgical method to help with sagging breasts.
