How many times can you have your breasts injected with fat transfer? (Photo)

There isn't necessarily a limit of number of procedures per se - you may need multiple sessions to get you to the desired size and shape. This may be contingent on the amount of fat available for liposuction/harvest. Based on the photograph provided, you would benefit from a revision of the left side to address your areola being too high and bigger and matching the other side.
Typically, cosmetic surgeries are not covered by insurance, even for the unfavorable outcome. In general, fat grafting is covered by insurance for breast reconstruction after breast cancer, not after a cosmetic revision.
Hope this helps!

Hello and thank you for your question! The short answer is, there is no "limit" to how many times a certain body site, including the breasts can receive fat as a transfer procedure. However, every patient and case is unique. There may be a lack of quality donor site to harvest the fat from that limits the number of fat transfer procedures, or there may be certain factors of the donor site such as the quality of the skin/tissue envelope, amount of scarring/fibrosis from prior procedures, etc that may limit the number of fat transfer procedures that a particular surgeon would recommend doing. Ultimately, an in-person consultation with a board certified plastic surgeon will be best to counsel you the best options for your unique case! With regards to your secondary question, I am not familiar with the acronym OHIP, but assuming this is an insurance plane, typically fat grafting may only be covered through insurance as a reconstructive surgery after mastectomy/lumpectomy. Speaking to your insurance provider about your specific case would give you the most concrete answer there.

As long as you have donor fat, fat can be added to breasts waiting at least 6 months between each donation. Fat transfer for volume is cosmetic and I would suspect (I do not work in Canada) that this is not covered by insurance. It is not covered in the US except for ladies who need reconstruction after cancer and some trauma.
