What to do about breast deflation after breastfeeding

After breastfeeding, breast atrophy may occur. In daily diet, one can consume more foods rich in collagen, such as white fungus, bird's nest, pig trotters, etc., though long-term consistent intake is required. Appropriate chest exercises, such as those targeting the pectoralis major and pectoralis minor muscles, can also help enhance chest muscle strength. Additionally, autologous fat grafting is another option for improvement, which typically involves harvesting excess fat from other parts of the body, processing it, and then injecting it into the breasts.
