In fat grafting and secondary hybrid breast augmentation,

the key factor is how well the grafted fat survives.

At AVAN TOKYO, we recommend drinking 1 liter of soy milk daily for the first postoperative month as part of postoperative care.

This is not a trend, but a medically reasonable approach to optimizing the graft environment.

Medical rationale

• Soy isoflavones have mild estrogen-like effects that may support a favorable glandular environment
• Plant-based protein and essential amino acids support tissue repair and angiogenesis
• Genistein has anti-inflammatory and antioxidant properties, which may help reduce fat necrosis and nodules

Case overview

This patient previously had a submuscular silicone implant and underwent fat grafting

(190 cc right / 180 cc left) to improve implant visibility and add natural volume.

By maintaining 1 liter of soy milk daily for one month,

good volume retention was observed even in the medial cleavage area.

Key point

Postoperative outcomes are not determined by surgery alone.

More than 50% depends on postoperative care and lifestyle management.
