BiVol · 4th-Generation Breast Augmentation · Developed by Bong Bong Plastic Surgery · KIPO Trademark Registered
For decades, breast augmentation has evolved around the silicone implant. From the first-generation saline devices, to second-generation smooth-surface implants, to third-generation textured cohesive-gel implants — each generation refined its predecessor, yet fundamental issues remained: foreign-body sensation, capsular contracture, and periodic replacement.
BiVol, developed by Bong Bong Plastic Surgery, begins from a different question: "Rather than perfecting the implant, could we build a breast without an implant at all?" This article walks through the science behind BiVol, the practical differences compared to conventional implants, and who might be the right candidate.

What is BiVol?
BiVol is a world-first 4th-generation breast augmentation technique, developed by Bong Bong Plastic Surgery and trademark-registered by the Korean Intellectual Property Office (KIPO)1. Instead of inserting a silicone implant, BiVol individually designs and places biocompatible Acellular Dermal Matrix (ADM) and related biomaterials tailored to each patient's body2.
The most important feature is that these biomaterials are gradually replaced by the patient's own tissue over time. Immediately after surgery, the placed ADM provides volume; but over the following months, the body regenerates collagen and native tissue in its place — until the augmented volume becomes genuinely part of "your own body." Detailed technical documentation and academic publications are available at the official BiVol website (bivol.co.kr).
Not the age of implants, but the age when the body builds its own volume. BiVol is the first sentence of that chapter.

Why "4th generation"?
Breast augmentation has evolved along the following trajectory:
- Generation 1 — The dawn of silicone implants. Limited safety and naturalness.
- Generation 2 — Smooth-surface cohesive-gel implants. Improved feel.
- Generation 3 — Textured and nano-surface implants. Reduced capsular contracture risk.
- Generation 4 (BiVol) — No implant is used at all. A biomaterial approach that gradually converts to the patient's own tissue.
While earlier generations improved the "material" of the implant, the 4th generation redefines the concept of the material itself. Rather than inserting a foreign object, BiVol provides a scaffold that guides the body to build its own tissue — that is the core philosophy of BiVol.
For context, Hybrid Augmentation Mammoplasty, which corresponds to the third generation, combines an implant with autologous fat grafting — a technique for which Dr. Seongsoo Park published the first Korean paper in 2012. To compare the two side by side, visit the official Hybrid Breast Augmentation site (hybridbreast.co.kr), which documents 16 years of international academic evidence.
Practical differences vs. traditional implants
Beyond mechanistic differences, the following comparison summarizes the practical distinctions at the outcome level.
| Comparison | Gen 3 traditional implants | Gen 4 BiVol |
|---|---|---|
| Material inserted | Silicone implant | ADM · PDLLA · HA (replaced by autologous tissue) |
| Size customization | Fixed factory sizes | Precisely tuned to the desired volume |
| Feel | Foreign-body sensation characteristic of implants | Similar to natural breast tissue after remodeling |
| Capsular contracture | Present | Fundamentally reduced |
| Periodic replacement | Review recommended around 10 years | Not required — replaced by native tissue |
| Recovery | 2–4 weeks | 3–5 days |
| Asymmetry correction | Limited | Left/right individually designed |
The two points worth highlighting are the freedom of size customization and recovery time. Traditional implants force you to choose from fixed sizes such as 275cc or 300cc, whereas BiVol allows the shape and quantity of ADM to be finely tuned to each individual's anatomy. For patients with breast asymmetry, both sides can be independently designed — a meaningful advantage.
The 3–5 day recovery window applies to office-based work. Sutures are removed at day 7, light exercise resumes from week 3, and vigorous exercise from week 6. Individual recovery varies, so regular follow-up is essential.
Unlike Hybrid Augmentation, which combines an implant with autologous fat, BiVol contains no implant at all. Slender-framed patients and those bothered by foreign-body sensation tend to prefer this option. That said, if the goal is a very large augmentation (>500g), implant-based procedures may still be more suitable — so we recommend evaluating all options during your consultation.
The four biomaterials that complete BiVol
BiVol is not a single substance — it is completed by a combination of four biocompatible biomaterials. The ratio of each material is individually designed based on the patient's body type, desired volume, and tissue characteristics.
ADM
Cellular components are removed to minimize immune response. A well-established biomaterial widely used in breast reconstruction.
PDLLA
A bio-degradable polymer that breaks down over time while stimulating the body to produce native collagen.
High-purity HA
Provides immediate volume and hydration, completing a natural feel and soft contour.
Stem Cells
A cell-based technology that enhances graft survival during autologous fat transfer, added when a more natural finish is desired.
Is ADM truly safe?
This is the most common question. ADM has a long clinical track record in breast reconstruction and shows a very low risk of immune rejection thanks to its acellular processing3. Recent research shows that micronized ADM (mADM) does not act merely as a volume filler but as a regenerative scaffold that supports cell infiltration, neovascularization, and collagen remodeling4. A 2-year MRI-based volumetric study reported only a 3.7% volume loss with paste-type ADM, demonstrating long-term volume retention5. Bong Bong Plastic Surgery uses only certified ADM with domestic and international clinical data, and evaluates suitability for each patient through preoperative safety testing.
Who is BiVol suited for?
BiVol is particularly well suited to patients with the following concerns. Of course, suitability depends on individual body type and tissue characteristics, and the final decision is made only after a detailed consultation and diagnostic workup.
- Concerned about foreign-body sensation — patients who find the feel of silicone implants uncomfortable
- Wary of revision surgery — those wishing to avoid long-term issues like periodic replacement or capsular contracture
- Want precise size control — patients who prefer finely tuned volume over pre-set implant sizes
- Have asymmetry — patients seeking precise correction of left–right differences in size or shape
- Need fast recovery — those returning quickly to work, childcare, or other responsibilities
- Prioritize natural results — patients wanting a contour that looks and feels like their own body
Surgical process and recovery timeline
BiVol at Bong Bong Plastic Surgery is not just a single procedure — it operates as a full system, from preoperative diagnostics through postoperative care. The entire process consists of five stages:
-
STEP 01
1-on-1 In-depth Consultation
Body analysis, desired volume, and lifestyle are all considered. The chief director consults personally.
-
STEP 02
Safety Workup
Blood testing, breast ultrasound, ECG, and other preoperative diagnostics to confirm surgical suitability.
-
STEP 03
3D Custom Design
ADM shape, quantity, and material ratio are individually designed. Asymmetric cases are planned side-by-side.
-
STEP 04
Surgery (~60 min)
Performed under general anesthesia. Surgery is completed within an hour, and same-day discharge is possible.
-
STEP 05
Postoperative Care
Suture removal at day 7, follow-up assessments, and annual long-term tracking — all managed as one system.
Recovery timeline
Recovery varies from person to person, but the general timeline is as follows.
- Day of surgery — Discharge after anesthesia recovery. Take prescribed medication.
- Days 1–3 — Peak swelling and discomfort. Strict rest recommended.
- Days 3–5 — Return to office-based work possible.
- Day 7 — Suture removal. Showering permitted.
- Week 3 — Light exercise may begin.
- Week 6 — Vigorous exercise and cardio resume.
- Months 3–6 — Autologous tissue replacement completes. Final shape settles.

Closing thoughts
The goal of breast augmentation is, in the end, naturalness and confidence. BiVol does not simply refine the implant further — it redefines the material itself, pursuing both the invisible naturalness of a body that feels like your own and the reassurance of not needing revision surgery.
As with any surgery, no single procedure is right for everyone. Depending on your body type, desired volume, and recovery constraints, autologous fat augmentation, hybrid (implant + fat), or a traditional implant may be more suitable. That is why we recommend comparing all available options during consultation and selecting the approach best matched to your goals.
