Sculptra for slight breast enhancement?

Hi, I've been contemplating implants for some time but the idea of surgery & foreign objects in my body is somewhat confronting. I don't want large breasts but being nearly 40 & lost weight I'd love a little more fullness upper pole. I was wondering if Sculptra is an option for a minor breast augmentation or if there are any other less evasive options than fat transfer. I'm reluctant to gain only to lose again due to the possibility of skin sagging. Any advice would be greatly appreciated Sarah
