— The Essential Post-Operative Care Guide —

Fat grafting breast augmentation uses a patient’s own fat cells to naturally enhance breast volume.

It offers a soft, natural look and feel, and is one of the most discreet breast augmentation methods.

However, the most critical factor determining the final result is fat survival.

For example, if 300 cc of fat is injected per breast, the final volume that remains is typically 30–50%.

This percentage varies greatly depending on how you spend your postoperative period.

Here, we explain three key habits that significantly improve fat survival and reduce complications.

1. Prioritize a Plant-Based, High-Protein Diet for 1.5 Months

Transferred fat cells are “living cells.”

Their survival depends on whether they receive enough oxygen and nutrients through newly formed blood vessels.

One of the most effective dietary habits is drinking 1 liter of soy milk per day.

Soy provides plant-based protein and isoflavones, which support hormonal balance and fat stability.

Recommended foods

• Soy milk
• Tofu, natto, miso
• Edamame
• Eggs, salmon
• Vegetables and fruits

Foods to avoid

• Fried foods, margarine, fast food (strongly inflammatory)
• Sugary snacks and refined carbohydrates

Inflammatory foods increase systemic inflammation, raising the risk of fat necrosis and hard lumps.

2. Light Physical Activity to Promote Blood Flow (No Intense Exercise)

Blood flow plays a key role in delivering oxygen and nutrients to the transplanted fat.

Light exercise can enhance fat survival.

Recommended activities

• Walking
• Gentle stretching
• Light arm mobility (without shaking the chest)

Avoid

• Running, HIIT, weight training
• Movements that shake or compress the breasts
• Heavy arm workouts

The goal is to protect the breasts while improving circulation.

3. Prioritize High-Quality Sleep

Sleep supports tissue repair, hormone regulation, and inflammation control—all essential for fat survival.

Sleep deprivation elevates stress hormones and systemic inflammation, making fat cells more likely to be absorbed.

Sleep recommendations

• 6–7+ hours of quality sleep daily
• Avoid screens and caffeine before bed
• Use relaxing music or dim lighting to improve rest

Good sleep is a crucial part of postoperative recovery.

Conclusion: Post-operative Care Is the “Second Half of the Surgery”

Successful fat grafting is determined not only by surgical technique,

but also by how well you manage your body afterward.
