After breast augmentation with autologous fat transplantation, the hardening of the chest is the normal stress protection response of the body after tissue trauma, and does not require any treatment, not to mention hot and cold compresses. Postoperative candidates should reduce strenuous activities to prevent the fat tissue from moving down. The patient should take the supine position and try to keep this position for 48 hours after surgery. There is a risk of downward movement of the fatty tissue due to gravity, so you can wear a stretchy garment wrap or sports underwear that can be lifted slightly in order to maintain a good shape of the breasts after surgery.
