MOTIVA VS MENTOR VS ALLERGAN BREAST IMPLANTS SEOUL 2026

Walk into any Gangnam breast augmentation consultation and you will be handed three sample implants to squeeze: a round Motiva from Establishment Labs, a Mentor MemoryGel from Johnson and Johnson, and an Allergan Natrelle Inspira. The surgeon will quote you three different KRW prices and three different warranty cards, and most foreign patients pick based on which one feels softest in the hand. That is the wrong test. The real differences live in shell technology, rupture-replacement policy, size step increments, and what happens to your warranty if you fly home to Berlin or Melbourne six months post-op.

This guide compares the three brands head-to-head on the five decisions that actually change your five-year outcome.

If you have already picked implants and want to pick a surgeon, the ranked Seoul buyer's guide covers the clinic-side decision.

SHELL TECHNOLOGY AND SURFACE

Motiva uses the SmoothSilk shell, a nano-textured surface with a Qid identification microchip embedded in every implant. The surface sits between smooth and macro-textured, which Establishment Labs argues lowers both capsular contracture rates and the ALCL risk that forced macro-textured implants off most markets in 2019. Shell integrity testing on Motiva Ergonomix round implants shows TrueMonobloc construction, meaning the gel and shell cure as one piece, reducing shell-gel delamination risk. For Seoul patients this matters because almost every Motiva sold in Korean clinics is the Ergonomix round, and the shell choice is baked in.

Mentor MemoryGel uses a smooth or Siltex micro-textured shell with cross-linked silicone gel. The brand has a longer FDA follow-up dataset than Motiva, including the ten-year MemoryGel core study which reported capsular contracture rates around 9 percent and rupture rates around 24 percent at ten years. Those numbers are higher than the newer Motiva data suggests, but the ten-year horizon is actually measured rather than modeled. Korean clinics that stock Mentor usually offer only the smooth round profile.

Allergan Natrelle Inspira uses a smooth responsive-gel shell paired with cohesive silicone. The TruForm gel series ranges from TruForm 1 (softer, more mobile) through TruForm 3 (highly cohesive, maintains shape under pressure). Allergan pulled its Biocell macro-textured line in 2019 after BIA-ALCL exposure, which means every Natrelle in a Seoul clinic today is smooth. Of the three brands, Allergan offers the widest gel-cohesivity range in a single catalog.

WARRANTY AND LIFETIME POLICY

This is where the brands diverge most, and where foreign patients get the biggest surprise after they fly home. Motiva offers the Always Confident Warranty, which includes lifetime rupture replacement plus up to five years of financial assistance toward revision surgery costs. The warranty is honored at any Motiva-certified surgeon worldwide, including surgeons in your home country, which matters if revision happens in Sydney rather than Seoul. The surgeon must be Motiva-registered, so you will want to confirm your home-country clinic is on the list before you fly.

Mentor's standard warranty includes lifetime product replacement for confirmed rupture plus the MentorPromise Protection Plan, which pays up to 2,400 USD toward revision surgery costs for ten years from implantation. Capsular contracture Baker Grade III or IV is covered for the same ten-year window. The warranty is global and honored by any Mentor-trained surgeon.

Allergan ConfidencePlus covers lifetime rupture replacement and offers up to 3,500 USD toward revision costs for the first ten years. The Natrelle rupture-replacement provision has the smoothest claims process of the three brands based on patient reports, but Allergan's revision cost reimbursement caps lower than Motiva's five-year coverage in absolute terms depending on which revision happens when. All three warranties require you to register your implant serial number within 90 days of surgery.

SIZE STEP INCREMENTS AND SIZER AVAILABILITY

Motiva Ergonomix comes in 10 to 20 cc increments across the Full, Demi, and TrueFixation profiles, with sizes running from roughly 125 cc up to 695 cc. The size-step granularity is the finest of the three brands, which lets surgeons dial in volume to within 20 cc of your tissue envelope. Korean clinics stock the full range because Motiva is now the top-selling implant brand in Seoul breast augmentation.

Mentor MemoryGel ships in moderate, moderate plus, and high-profile shapes with 25 to 50 cc increments between sizes. The granularity is coarser than Motiva, and the gap between a 325 cc and a 375 cc implant can be the difference between a conservative result and an obvious one. Smaller clinics often stock only moderate profile Mentor, so if you want the high-profile projection you may need to confirm inventory a week in advance.

Allergan Natrelle Inspira sits in the middle on granularity with 20 to 30 cc increments and five gel-cohesivity options per size. The sizer selection is the most comprehensive if your surgeon wants to try multiple cohesivity levels during the sizing fitting. If your tissue is thin, Allergan's TruForm 3 may give you better shape retention than the equivalent softer gel options from the other brands.

KRW PRICE IN SEOUL CLINICS 2026

Expect Motiva Ergonomix to add roughly 1.5 to 2.5 million KRW over a baseline round-saline price depending on size, which puts total procedure cost in the 7.5 to 11 million KRW range at mid-tier Gangnam clinics. Premium rhinoplasty-boutique style clinics in Apgujeong charge 12 to 14 million KRW for the same implant plus their surgeon fee. Motiva's price premium reflects both the shell technology and the fact that it is the most-requested implant among international patients in Seoul.

Mentor MemoryGel typically prices 1 to 1.5 million KRW below Motiva for comparable size, placing total procedure cost in the 6 to 9 million KRW band at the same mid-tier clinics. The gap used to be larger before Johnson and Johnson repositioned Mentor pricing in Korea in 2024, but Mentor is still the price-conscious choice if you want FDA data behind your implant.

Allergan Natrelle Inspira sits between the two on price, usually 1 to 2 million KRW over Mentor and 500,000 to 1 million KRW under Motiva at the same clinic. Natrelle is also the easiest implant to source same-week in Seoul because Allergan Korea maintains the deepest regional inventory.

POCKET PLACEMENT AND BRAND PAIRING

The implant brand only drives half the aesthetic outcome. The other half is where the surgeon puts it. Dual plane placement works well with all three brands but shows the fewest rippling complaints with Motiva Ergonomix TrueFixation because of the shell's self-adhering surface. Submuscular placement is the safest default for thin tissue regardless of brand, and subglandular placement works best with the more cohesive gel options like Allergan TruForm 3. Pocket choice is often more consequential than brand choice, which the pocket placement breakdown covers in detail.

WHICH BRAND SHOULD YOU PICK?

Pick Motiva if you prioritize warranty breadth, you want the finest size increments, and you accept paying a 1 to 2 million KRW premium for the newest shell technology. Pick Mentor if you want the longest real-world safety dataset, you are budget-conscious, and your surgeon stocks the profile you need. Pick Allergan Natrelle if you want adjustable gel cohesivity to match thin or variable tissue, and your surgeon has deep Natrelle sizing experience. All three are safe in experienced Korean hands. The failure mode almost always traces back to pocket placement or surgeon volume rather than implant brand.

Clinics regularly cited for high-volume breast augmentation across all three brands include ID Hospital, April31 Aesthetics, Nana Plastic Surgery, Reborn Plastic Surgery, and VG Plastic Surgery. Confirm current implant stock in writing before you fly, since inventory shifts quarter to quarter. If this is your first time running the consultation gauntlet, the first-time breast augmentation guide is worth a read.

IS ONE BRAND SAFER THAN THE OTHERS FOR ALCL RISK?

BIA-ALCL risk is now almost entirely associated with the macro-textured surfaces that have been off the market since 2019. Current Motiva, Mentor, and Allergan implants sold in Korea are smooth or nano-textured, and ALCL cases on these surfaces are vanishingly rare in published registries. Monitor for breast seroma, swelling, or capsular changes at any point after year one and report them promptly regardless of brand.

DOES THE WARRANTY TRANSFER IF I MOVE COUNTRIES?

Yes for all three brands, provided your home-country surgeon is registered with the implant manufacturer. Motiva, Mentor, and Allergan all maintain global warranty databases keyed to your implant serial number. Register within 90 days of surgery through the Korean clinic, keep the warranty card with your passport, and confirm your target home-country revision surgeon is on the manufacturer's registered list before you move.

HOW OFTEN DO THESE IMPLANTS NEED REPLACING?

None of the three brands require replacement on a fixed timeline. The old 10-year replacement rule came from early-generation implants and does not apply to current cohesive gel generations. Replace only when imaging confirms rupture, when capsular contracture becomes symptomatic, or when you want size or shape change. Expect annual self-exam plus MRI or ultrasound surveillance starting year five to seven depending on your surgeon's protocol.

CAN I PICK THE BRAND OR DOES THE CLINIC?

You can and should pick the brand. Reputable Seoul clinics stock all three and will let you choose during the sizing fitting after reviewing your tissue and target volume. If a clinic refuses to quote a specific brand or steers you only toward one without clinical justification, that is a sign they have a volume agreement with a distributor rather than a patient-first fitting process. Walk out and consult elsewhere.

WHAT HAPPENS IF AN IMPLANT RUPTURES IN KOREA DURING RECOVERY?

All three warranties cover rupture replacement product cost at any point for the lifetime of the implant, and the Korean clinic will typically waive its surgeon fee for revision within the first 12 months post-op as a goodwill measure. Confirm the clinic's intraoperative-rupture and early-rupture policy in writing before you book. For a wider look at what revision looks like at any point post-surgery, the implant removal guide covers en-bloc, capsulectomy, and explant pathways.

HOW DO I KNOW WHICH BRAND MY SURGEON PREFERS AND WHY?

Ask directly: which brand did you implant most often last year, and why. A surgeon who defaults to one brand usually has 500-plus cases of muscle memory with that specific shell and profile, and the familiarity reduces operating-room time and complication risk. That said, a volume-only answer is a yellow flag. The right answer connects brand choice to tissue type, lifestyle, and your target projection, not just to what sits in the fridge.
