Born with one dimple on my left butt cheek, would a fat tranfer help?

Your best option is fat grafting.  It would probably be best to fat graft both sides, adding more to the affected side for symmetry.  

This is difficult to answer without pictures. Cellfina in combination with Sculptra or renuva, and body treatments like Exilis Ultra/Venus Legacy, Cellutone/z wave can give improvements for this. I recommend getting a formal evaluation with an expert. Best, Dr. Emer

Dear pollymw,it is hard to tell without an examination or at least a photo. I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.Daniel Barrett, MD, MHA, MS

You might search for a plastic surgeons that uses a device called Cellfina.  This is a new technology that is scarless and may really help.

A photograph would help immensely.  If there is a correction to be made, certainly fat transfer is a good option.  Without a photo, this is difficult to assess.  You may not need an invasive procedure, therefore, a consultation would be the best route for you to proceed with a treatment.

Hello, thanks for your question and provided information as well.. You need to provide pictures or have a consultation with a BC plastic surgeon. In some cases it can be corrected, you need to consult first. 

need to see pictures, I usually release these with a needle which is very effective and permanent and can be done under local anesthetic. No need fro expensive machines or fat grafting
