How to correct breast asymmetry? Left breast is half a cup size smaller than the right (Photo)

I can see the asymmetry in the photo. The right breast has more volume AND more ptosis with the breast shape slightly more relaxed with a lower nipple position. The problem with addressing the asymmetry with adding volume to the smaller, tighter side is we can actually exacerbate the asymmetry as the breast will become more tight and higher while the other breast will remain looser and lower. Perhaps the best direction would be to perform a small vertical lift on the right side to correct the underlying soft tissue excess. Having said that, your comment "to justify some kind of corrective surgery?" is valid as your breasts are natural and overall with good shape and volume. It may behoove you to wait until after having children and growing older when things will change more and there will be more reason to operate. Thank you for sharing.

First off, no woman's breasts are entirely symmetrical--there are always slight differences in shape and/or volume. That being said, it is entirely up to you if the difference is enough to warrant a procedure to get them closer in volume. For a lot of women who I have treated, they notice volume differences both in the appearance of their breasts and in how they fit in clothes/bras/swimsuits/etc, and do appreciate the improved symmetry after a procedure. Fat transfer is a great way to correct small differences, especially when one breast is at the desired size.

You are an ideal candidate for fat grafting to the smaller breast .
I add PRF to my fat grafts to encourage fat graft survival.
I use the same technique for restoring fullness to the face.
