Small/Saggy Breast Fat Transfer

Through a combo of bad genetics, weight loss, & breastfeeding I have a couple of little flapjacks on my chest. I'm pear shaped and have lots of fat from my lower body to share with the rest of my body. I'm pretty resolved on not getting implants & want to go down the fat transfer route only. I'm aware of the risks with cysts & difficult breast imagining. I already have issues with imaging because my breast tissue is so fibrous.

Two questions 1) Will a doctor do the procedure without a breast lift? I don't want a bunch of scars. I hyperpigment really easily. I'd rather get the little bump in volume and leave it at that. 2) Any recommendations for doctors that do fat transfers in the greater LA area?
