Drinking soy milk does not have the role of breast enhancement, it is believed that soy milk contains soy isoflavones, and estrogen has a similar biological role, but because the amount of soy isoflavones contained in soy milk is relatively small, the normal drinking soy milk on the human body is relatively small, so it can not play a role in breast enhancement. Once puberty development is over, no special drugs can play a role in breast enhancement, so do not recommend indiscriminate use of drugs or breast massage treatment. At present, the only effective way to enlarge the breasts is still through surgical treatment, you can choose to implant breast enlargement or autologous fat breast enlargement surgery. Normally, you can also do more upper limbs or chest strength exercise, local muscle shaping can also play a role in improving the role. Usually eat more protein-rich foods, fresh vegetables and fruits, ensure sufficient sleep, and try to go to the regular hospital for consultation.
