Fat transfer with low body fat

How much body fat is required to do fat transfer to go from 34A to 34C (assuming using Brava prep)? I have very lean body composition (in the mid or high teens %bf) and it’s very hard for me to gain fat but I gain muscle unusually easily for a woman. I definitely don’t want to lose any from my hips or butt, but there’s a little bit in my inner thighs I could do without. Any hope for this approach?

Procedure: Breast Augmentation

In my hands that transfer the breast might have or retention of 50% to maybe 70% of the fat that is injected. When you don't have much fat to inject the biggest improvement with fat ingestion of the breast will be to the top half of the breast and the outer portion. Improving that little hollow dip is what the fat transfer will do better. The breast may not be a lot bigger but it will look better with better cleavage in the bra. So even if you don't have much fat I think you can get an improved look for the breast.

Thanks for your question,

On average about 40-50% of fat that is injected gets absorbed by the body. From the body type you are describing it seems like you may not have enough fat to go up two cup sizes. It may best to supplement any fat grafting with a small breast implant. Without examining you, it is impossible to say what procedures would be best.

Also note that liposuction in people with an very low BMI who do not have much fat to begin has a higher chance of contour irregularities in the areas where fat is taken from

Please consult with a board certified plastic surgeon to determine which procedures are best to achieve your goals.

Best wishes!

Thank you for sharing your question. In the best of hands the amount of increase per grafting session is approximately a cup size. Based on your narrative if your inner thighs are your only repository of excess fat it would be extremely unlikely to be able to achieve your goals without the use of implants. You can fat graft along with implant placement if you prefer to further refine results.

Dont waste your time or money. IF you want larger breasts have an augmentation with smooth saline or silicone implants. More than half of the fat will go away and you could end up with lumpy un appealing breasts.

This would be a very trying ordeal, and not worth the effort. Breast implants are the way to go considering your body composition. Fat grafting can be unpredictable, especially in large volumes. Also, given the fact you have little fat to give, you may have donor site scars and lumps that you would greatly regret.
