Hello dear, thanks for your question.
How long I have to wear my post-surgical bra after a Breast Augmentation?
After a breast augmentation we have to protect our implants of possible movements out of the pocket already made by our surgeon. I always recommend my patients to wear their prost-surgical bra for at least 3 months from surgery day.
Then you can change to an sports bra and continue using it for at least 6 months from surgery. It is a process and we have to give support and protection to our breasts.
Compression is good for our breasts after a breast augmentation, we have to protect our post-surgical results and we will have a great surgery outgoing!!
But I recommend to ask to your PS, because each surgeon has their own politics.
Good luck :)
