Does Brava/Noogleberry make breasts more saggy if breasts are small and have moderate sagging already?

Good question, in theory if you pulled the skin and stretched it the degree of sagginess would go up, but you should only be using these devices in preparation for surgery. I have found classic breast lifting procedures quicker, cheaper, and more reliable thoughGOOD LUCK 

Brava and Noogleberry use suction to stretch skin and supposedly enlarge the breasts to a small to moderate degree at most, and the result is typically temporary.  Skin stretching can lead to more droopiness if you are prone to having saggy breasts to begin with.  I don't think either of these procedures will provide you with the enhancement that you desire.Consider a breast lift, with or without augmentation(implants) as the "gold-standard" options to give you with the results that you want.Nothing replaces  a consultation with  a board certified plastic surgeon to learn about your options and have all your questions answered.
