Unexisting underboob - is it possible to create with fat transfer?

Dear Optimistic493474,
it is hard to tell for sure without an examination. If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.

It is not uncommon for the breast to be underdeveloped in the inferior aspect. The most common form of treatment is an implant. On occasion, tissue expansion may be required. Because the skin/ tissue which will now be part of the lower breast was recruited from the the upper abdomen, it often is quite thin compared to surrounding tissue. Fat grafting can be used to thicken this. It will potentially improve the original fold at the bottom of the breast to make it less visible on the newly augmented breast.

Fat alone may improve the lower pole. A few things would be required such as a fold that is not overly creased, some laxity to the skin to place fat and some fat to harvest; amongst other things. This is fairly nuanced. The best option would be to see someone that does a lot of fat grafting to get their opinion. It is also possible that more than one session of fat transfer may be needed to get the best result.

Techniques like skin stretching and fat transfer may be considered, but it depends on individual anatomy and goals. Consult with a board-certified plastic surgeon to explore your options.

Best of luck !

Yes, fat could be added if you have donor fat. Fat is placed into actual breast tissue. If you have little breast tissue now, you may need more than one transfer. I would suggest meeting with a board-certified plastic surgeon and discussing your concerns and options.

It’s difficult to make an assessment based on your description. I suggest having a few in person, consultations with plastic surgeons in your community to get a better understanding of what can, or cannot be accomplished with various plastic surgical procedures.
