How can I make my saggy breasts perkier and fuller without any form of surgery?

You will probably need surgery. Far more important than the technique
is the skill and experience of your plastic surgeon. Choose your surgeon rather
than the technique and let them explain why one technique may be better than
another.

See the below link on some
suggestions on finding the most qualified Plastic Surgeon for a Breast Augmentation. 

It’s not unusual for patients
to be concerned about breast sag and the overall appearance of their
breasts.Many of these patients would
like to undergo breast lift surgery but are fearful of the scarring that’s
associated with this procedure.These
patients frequently look for alternatives that avoid surgery and scarring
that’s associated with this operative procedure.Unfortunately, at this time, there’s no way to treat
significant breast sag without breast lift surgery.Breast lift surgery is the only technique
that can lift the breast into normal position.Unfortunately, this can’t be accomplished without incisions that remove
excess skin.This will obviously create
scarring which may be visible.If you’re concerned about breast sag, it’s appropriate to
consult a board certified plastic surgeon with experience in this area.This surgeon should be able to formulate a
treatment plan that addresses your anatomic findings and hopefully achieve your
aesthetic goals.

Good and frequently asked question.  Unfortunately, once the skin has been stretched, surgical intervention is the only way to correct the ptosis (sag) of breasts. A well supported bra worn as much as possible may delay sagging but gravity will eventually win the battle. All other methods of enhancing ones breast non surgically have never been proven to work and will be a waste of your hard earned money. Hope this has helped.
