When people come in for a breast surgery consultation, the first question is almost always: "Is Mentor better, or Motiva?" A quick search turns up dozens of implant names, and every ad claims a different advantage. But here's the honest answer from someone who has performed breast augmentation for over 25 years.
The core message
The implant's "name" is not what creates the result.
What determines the shape five or ten years from now is the design of the "pocket" (the space) the implant sits in and the lower support structure (Internal Bra).
Comparing the Three Major Implant Brands
Here's a comparison of the three implants most commonly used in Korea. Each has its own strengths and weaknesses, but the bottom line is this: no matter which implant you choose, problems can develop over time if the "space it sits in" isn't engineered with precision.
| Category | Mentor® | Motiva® | BellaGel® |
|---|---|---|---|
| FDA approval | ✅ Fully approved by the US FDA | ❌ Not FDA-approved (holds CE marking) |
❌ Not FDA-approved (approved by Korea's MFDS) |
| Long-term tracking data | Over 10 years of large-scale clinical data |
Relatively shorter follow-up period |
Mostly domestic data limited international comparison studies |
| Gel characteristics | Cohesive gel (MemoryGel / MemoryShape) |
ProgressiveGel (shape-shifts with body temperature) |
Micro-textured cohesive gel |
| Feel | Soft with natural elasticity | Very soft | Relatively soft |
| Shape retention | Excellent (adjustable cohesive density) | Fluid (shifts with body temperature) | Good |
| Used at LaPrin | ✅ Exclusively used | ❌ Not used | ❌ Not used |
The reason LaPrin uses Mentor® exclusively is simple. Full US FDA approval means the implant has passed the strictest safety and durability testing available, backed by over 10 years of long-term tracking data. What goes into a patient's chest should not be "whatever's trending" — it should be an implant that has been proven over time.
The 'Pocket' Matters More Than the Implant
Here's an important fact to understand. No matter how good the implant is, if the space it sits in (the pocket) isn't precisely engineered, the following problems can develop.
Bottoming Out
The implant shifts downward, the lower fold collapses, and the nipple ends up pointing upward.
Symmastia
Both implants shift toward the center, erasing the natural boundary between the breasts.
Capsular Contracture
A hardened capsule forms inside the pocket, making the breast firm and distorting its shape.
Animation Deformity
The implant shifts along with muscle movement when you move your arm, creating an unnatural shape.
These problems are not caused by the implant itself. They occur when pocket design and lower support are inadequate. The same implant can produce completely different results depending entirely on how the pocket is constructed.
How LaPrin 4D Designs the Pocket
LaPrin's 4D breast augmentation perfects the space the implant will occupy before the implant is ever inserted. Here, "4D" refers to the concept of adding a time axis to the standard width, height, and depth (3D).
Step 1 — Multiplane Pocket Formation
We use multiple tissue layers together — glandular tissue, the pectoralis major, fascia — to create the pocket where the implant will sit most stably. Rather than simply placing the implant under the muscle, we design upper pole volume, side contour, and fold position all in 3D.
Step 2 — Internal Bra Lower Support
We precisely suture the lower portion of the pocket to create a support structure that functions as an "internal bra." This structure prevents gravity-driven bottoming out and keeps the lower fold from collapsing over time.
Step 3 — Designing for Time
We don't just aim for a beautiful breast right after surgery — we design for a shape that holds its original form even 5 or 10 years later. This is a "design that outlasts time," accounting for gravity, skin aging, and weight change.
The result of 4D pocket design
According to external literature, a cohort of 867 cases of 4D multiplane breast augmentation reported a Baker III–IV capsular contracture rate of approximately 0.91%. This figure illustrates the importance of pocket design and Internal Bra support.
(This figure comes from an external study and does not guarantee the same outcome for every patient.)
3 Questions You Should Always Ask When Choosing an Implant
There are questions that matter more at your consultation than the implant brand.
- "How do you construct the pocket?" — Ask whether it's a simple dual-plane technique, a multiplane technique, and whether there's a lower support structure.
- "How do you prevent bottoming out and symmastia?" — Ask whether they use an Internal Bra or an equivalent lower reinforcement technique.
- "What does your long-term tracking data look like?" — Ask to see results beyond just immediate post-op photos — ideally at 1, 3, and 5+ years.
Any implant brand your surgeon handles with confidence and that has solid long-term data behind it is a fine choice. What really makes the difference is the philosophy and skill behind how the surgery is designed.
