Can I use fibroblast for a breast/nipple lift?

I had fibroblast on my face with really good results. I have also read that it can be used to lift and tighten skin around the knees, so I am wondering whether it is also possible to use it to lift the breasts slightly? I assume the minor reduction of skin would give the same lifting benefits if a large area is treated? Would there be any reason not to try this? Thank you!
