I'm curious about the changes that occur after breast fat grafting!

I am a woman in my 20s considering breast fat grafting. I am curious about the changes that may occur after the surgery, particularly how the shape or size of my breasts will change. While the recovery period is important, I would also like to hear how the people around me reacted. For those who have undergone breast fat grafting, I am curious to know which clinic you chose and how satisfied you were. I would also appreciate it if you could share your experiences regarding pain or side effects!
