Fat graft breast augmentation is a procedure in which postoperative care is just as important as the surgery itself.

From clinical experience, it is fair to say that

more than 50% of the final result is determined by how you spend your downtime.

The One Thing You Must Never Do After Fat Graft Breast Augmentation

Smoking 🚬

To be very clear:

Smoking after fat graft breast augmentation is the worst possible choice.

Why smoking is so harmful (medical explanation)

After fat is injected, the fat cells are in an extremely delicate state:

• Blood vessels have not yet fully connected
• Oxygen and nutrient supply is limited
• Cells are deciding whether they will survive or die

Smoking causes:

• Nicotine-induced vasoconstriction (reduced blood flow)
• Carbon monoxide–related hypoxia (less oxygen delivery)
• Increased inflammation

As a result:

• Fat survival rate decreases
• Risk of fat necrosis and palpable lumps increases
• Infection and skin complications become more likely

👉 Even a single cigarette can reduce the survival of the transferred fat.

We strongly recommend complete smoking cessation

from at least 1 month before surgery until 1 month after surgery.

What You Should Definitely Consume After Fat Graft Breast Augmentation

Soy Milk 🥛

At AVAN TOKYO, we actively recommend

approximately 1 liter of soy milk per day during the first postoperative month.

Why soy milk works well with fat grafting

1. Isoflavones and mild estrogen-like effects

Estrogen plays an important role in:

• Maintaining a favorable breast tissue environment
• Supporting fat retention and survival

Soy isoflavones have a mild estrogen-like effect, which helps create an environment where transferred fat is more likely to survive—without excessive hormonal stimulation.

2. High-quality plant protein and essential amino acids

For fat cells to survive, the body needs:

• Tissue repair
• Angiogenesis (new blood vessel formation)
• Resolution of inflammation

Soy milk provides high-quality plant-based protein that supports all of these biological processes.

3. Anti-inflammatory and antioxidant properties

Soy contains compounds such as genistein, which are known to have:

• Anti-inflammatory effects
• Antioxidant properties

These may help:

• Suppress excessive inflammation
• Reduce the risk of fat necrosis and lump formation

“Eating Anything” Is a Common Mistake

After fat graft breast augmentation, it is a misconception that:

“Gaining weight will help the fat survive.”

In reality:

❌ Junk food

❌ High-fat, high-sugar Western diets

❌ Excessive alcohol intake

all promote inflammation and increase the risk of poor fat survival and lump formation.

The goal is not to “fatten the body,” but to keep the transferred fat alive.

A Clinical Example

The patient below underwent:

• Upper arm liposuction
• Fat graft breast augmentation
• 1 month postoperative follow-up

During the first month, she strictly followed:

• Complete smoking cessation
• Daily intake of approximately 1 liter of soy milk

As a result, she achieved excellent fat retention, even with a relatively modest injection volume.

Key Takeaways

After fat graft breast augmentation:

✔️ Never smoke

✔️ Maintain an anti-inflammatory lifestyle

✔️ Drink soy milk consistently

These simple steps can make a significant difference in both fat survival and final breast shape.

Our Philosophy at AVAN TOKYO Ginza Liposuction Clinic

At AVAN TOKYO, we believe that the result of fat graft breast augmentation depends on:

• Surgical technique
• Precise injection volume and layer selection
• Postoperative lifestyle guidance

Fat graft breast augmentation is not a procedure that ends in the operating room.

It is a process we complete together with the patient.
