In recent years, donor-derived adipose products have quietly gained attention in Western aesthetic medicine.

One such product is alloClae, a structural adipose allograft.

What is alloClae?

alloClae is a processed human adipose allograft, designed to preserve adipose architecture and extracellular matrix (ECM), aiming to mimic natural fat texture.

It has been explored in selected cases such as:

• Brazilian Butt Lift (BBL)
• Central cleavage and décolleté in fat graft breast augmentation
• Extremely lean patients with insufficient donor fat

Why this concept is emerging in the West

In the US and Europe:

• Organ and tissue transplantation is well established
• Allografts are widely accepted in medicine
• Regulatory and tissue-banking systems are mature

This has allowed donor fat concepts to extend into aesthetic applications.

Addressing the limitations of fat grafting

While autologous fat grafting remains the gold standard,

certain areas—such as the medial breast and décolleté—are known for lower fat retention.

alloClae may serve as a structural adjunct, not a replacement,

to support contour and volume in these challenging regions.

AVAN TOKYO’s philosophy

• Autologous fat first
• alloClae as a selective adjunct only
• Strict patient selection and layered injection strategy

Our goal is natural, safe, and predictable outcomes, not trend-driven treatment.

Conclusion

alloClae is not a miracle solution,

but it represents a potential evolution in body contouring,

when used thoughtfully and conservatively.
