Recovery time after breast fat grafting can vary depending on how many areas are used for fat donor sites. Like typical liposuction, these areas may be swollen, bruised, and uncomfortable for several days. Your breasts will experience some swelling and bruising, but little pain. Most patients return to work in a few days (for small cases) or in about two weeks (if more extensive liposuction is performed). You may begin your regular exercise routine in 10 to 14 days or as soon as your body has healed from the liposuction. Bruising and swelling can last up to three weeks, but all swelling should be gone in four to six months.
