Implants built the past. Regeneration is building what’s next.

For decades, body contouring meant one thing:Implants.They delivered volume — but with trade-offs: invasiveness, longer recovery, and results that didn’t always feel natural.

Today, patients are asking for something different:

• Less invasive
• More natural
• Longer-term tissue improvement

The rise of regenerative body fillers

With products like Sculptra expanding into body indications,a new approach is becoming clear:Don’t implant volume. Regenerate it.

PLLA works by stimulating the body’s own collagen,creating results that are gradual, natural, and long-lasting.

Why body treatments require a different approach？

Large areas like the hips, abdomen, and chest are far less forgiving.

The real challenge isn’t the injection —it’s how the material behaves after injection.

• Will it stay in place?
• Will it distribute evenly?
• Will results remain smooth at scale?

Why large-particle PLLA makes the difference

A 60–100μm particle design fundamentally changes performance:

Instead of dispersing too quickly or being cleared too early,
the microspheres:

✔ remain more stable at the injection site
✔ create a stronger three-dimensional scaffold
✔ stimulate collagen in a controlled, progressive manner

This is especially important in large-area treatments like hips and abdomen, where control matters more than speed.

This is especially critical for body treatments, where outcomes must be:

• Smooth across large areas
• Symmetrical
• Long-lasting (18–24 months)

Not replacing implants — expanding options

This isn’t about eliminating implants.It’s about offering a new pathway:

For patients seeking gradual, natural enhancement
For doctors seeking greater control with less invasiveness

Clinical Application: Hip Contouring

Hip treatments today focus on shape and lift, not just volume.

Recommended approach:

• Subcutaneous, fan technique (upper outer quadrant)
• 4 mL sterile water + 1 mL lidocaine
• ~6 vials per side
• 2–3 sessions, 4–6 weeks apart

For large-area treatments like the hips, material stability matters as much as technique.

This is where 60–100 μm PLLA can help support more controlled distribution and smoother results.

From breast rejuvenation to hip contouring,
PLLA body fillers are becoming a new standard in regenerative body aesthetics.Especially in high-volume treatments,precision is not about injection — it's about material behavior.Implants built the past. Regeneration is building what’s next.
