Choosing the Right Implant Size for Breast Augmentation2025.10.23
— Why “the same size as that photo” isn’t the right approach —
“I want the same implant size as this photo because her breasts look perfect!”
This is one of the most common misunderstandings in silicone breast augmentation ⚠️

■ Why the Same Implant Size Doesn’t Work for Everyone
Even if two patients use the same implant volume (e.g., 300cc or 400cc), the final result can look completely different depending on individual anatomy.
Several key factors determine how the implant will appear:
- Height and body frame: A large implant on a petite frame may look unnatural or create visible distortion.
- Skin elasticity: If the skin cannot stretch adequately, a large implant can cause thinning or drooping over time.
- Amount of breast tissue: Patients with little breast tissue may experience visible implant edges or unnatural projection.
- Rib cage shape: The width and curvature of the chest wall affect how much “height” and “cleavage” the implant provides.
Simply matching someone else’s implant size does not guarantee a beautiful or natural result ❌
■ Our Approach at AVAN TOKYO
At AVAN TOKYO GINZA LIPOSUCTION CLINIC, implant selection is never about numbers alone.
We carefully assess each patient’s skeletal structure, skin condition, and breast tissue to determine the most balanced size and shape.
We also specialize in Hybrid Breast Augmentation, which combines silicone implants with precise fat grafting to achieve:
- A smoother, softer transition between the chest and décolletage
- Natural-looking contours that conceal implant edges
- A more refined and feminine breast shape
This hybrid approach allows us to create a softer, more natural aesthetic than implants alone can achieve.
■ The Importance of Individualized Planning
A beautiful result is not about replicating someone else’s look —
it’s about finding the perfect harmony between your body and your goals.
Through personalized consultations and 3D simulation,
we propose a treatment plan that balances safety, proportion, and elegance for each patient.
■ Case Example
Below is an example of Hybrid Breast Augmentation (Motiva Demi 450cc, 1 month postoperative).
By combining an implant with subtle fat grafting, the result maintains fullness and smooth contour without an artificial look.
