    Which Breast Implant Is Right for You?
    A Body-Type Guide at NANA Plastic Surgery

    There is no single best implant, only the one that fits your body. Rib cage, tissue thickness, and the size you want all shape the choice. Here is how the four implant types at NANA compare, and how much your bust may change.

    Choosing a breast implant is not about finding the single best product. Everyone's body conditions are different, including the rib cage, the thickness of the soft tissue, and the size you want, so the right implant has to be judged from several angles through a careful consultation with a specialist. At NANA Plastic Surgery in Seoul, the breast clinic works with four implant types, BOUNS, Motiva, Mentor, and Sebbin, and matches the type to your body rather than applying one product to everyone. This guide walks through what each implant is known for, and how much your bust measurement may change with size.

    Key Takeaways

    • There is no universally best implant. The right one depends on your rib cage, soft tissue thickness, and desired size, judged in consultation with a specialist.
    • BOUNS is a newer type focused on holding the breast shape and a natural feel, with a wide range of sizes.
    • Motiva (FDA approved 2024) suits a smaller rib cage and thin skin, lowering rippling risk and the chance of a foreign-body sensation.
    • Mentor (FDA approved 2017) and Sebbin both suit asymmetry correction, with Mentor known for feel and proven safety and Sebbin for a firm, elastic shape.
    • An implant of about 250 to 300cc, a common choice, increases the bust measurement by about 5 to 6cm, roughly 2 to 3 cup sizes.

    How the Right Implant Is Chosen

    Because each person's body conditions differ, the rib cage, the thickness of the soft tissue, and the desired size among them, the implant that suits you is found through a detailed consultation with a specialist who weighs these factors from multiple angles. The four types below each answer a different set of needs.

    BOUNS, Motiva, Mentor, and Sebbin

    BOUNS

    BOUNS is a premium implant with a highly cohesive silicone gel and a durable multi-layer shell that gives strong recovery and long-term stability. An internal barrier layer lowers the chance of gel bleeding, and a refined range of profiles accounts for individual body shape and slight asymmetry, for a natural look and soft feel. It is offered in smooth and micro surface options. Standing, it falls in a natural teardrop shape; lying down, it spreads softly. It is registered and approved by Korea's Ministry of Food and Drug Safety (MFDS), and comes with a dedicated warranty program that supports free implant replacement when the warranty conditions are met.

    • Best for a small frame or narrow rib cage, thanks to a size range designed for Asian body types
    • Helps thin skin, minimizing rippling so the implant outline does not show
    • Restores upper-breast volume lost after childbirth or weight change
    • For those who want a natural silhouette that moves with the body

    Motiva

    Motiva is an ergonomically designed implant offered in Round and Ergonomix ranges. Its TrueMonobloc technology holds a uniform tension across the whole surface for a natural feel while reducing the immune response and the risk of capsular contracture. The silicone gel flows like real tissue, spreading softly when lying down and forming a teardrop shape when standing. A Blue Seal barrier layer lowers the risk of gel bleeding, and a built-in Q Inside Safety Technology UDI stores the implant's identification details. Motiva received final FDA approval in 2024, and the clinic reports a 10-year rupture rate below 1%. A warranty is offered on Motiva Ergonomix with Q, covering re-operation for rupture or grade 3 to 4 capsular contracture within 5 years of surgery.

    • For those who prefer a natural feel and movement
    • For those who value long-term safety and stability
    • For those who want a digital tracking and management system
    • For a small rib cage and thin skin, keeping the outline from showing
    • For those who want to minimize a foreign-body sensation

    Mentor

    Mentor, by Johnson & Johnson, is one of the longest-used implants in the world, with FDA safety certification in 2017. It uses a thin but firm shell with a high-density 100% fill gel that minimizes volume loss and rippling and holds volume and shape over time. It is available in several options, including Mentor Boost, Mentor Xtra, and Mentor Smooth, so the type can be matched to the individual. Mentor also promises a lifetime replacement policy across its full range when a re-operation is needed due to an implant problem.

    • Suited to correcting asymmetry with a range of types
    • For those to whom feel is important
    • For those who want an implant from a trusted company
    • For those who prioritize proven, long-established safety

    Sebbin

    Sebbin is a French implant with over 30 years of history, used in more than 75 countries and valued for its balance of quality and cost. It holds European CE and ISO certification and is approved by Korea's MFDS. A high-elasticity silicone gel gives a feel close to real breast tissue, and a micro-textured surface improves adhesion while helping reduce capsular contracture. An eight-layer shell withstands about 40% more pressure than the international standard, and a strong shell-and-gel bond lowers the risk of filler leakage if the implant ruptures. It comes in four types to suit different body shapes, in round and anatomic (teardrop) options. As some Sebbin products may not hold US FDA certification, it is worth confirming which certification the specific product carries.

    • Sublimity, a very fine high-micro-texture surface, for those who want both feel and stability, or have thin skin and contracture concerns
    • Integrity, a semi-smooth surface, for thin skin and those who prioritize a soft, natural feel
    • Purity, a traditional micro-texture surface, for strong fixation, contracture prevention, and a defined line

    Predicting Your Bust Size by Implant Volume

    Recently, many people choose an implant of about 250 to 300cc. In that case, the bust measurement increases by about 5 to 6cm after surgery, which is roughly 2 to 3 cup sizes.

    Implant volume Approx. bust increase Approx. cup change
    About 100cc About 2cm Reference point
    About 250 to 300cc About 5 to 6cm About 2 to 3 cup sizes

    These figures are a general guide. Actual sizing can differ by individual body type, so the right volume is confirmed during your consultation.

    Implant Sizing Charts by Brand

    Each implant type comes in a range of volumes, projections, and base widths. The charts below are a manufacturer reference only. Your actual size is confirmed during consultation, since it depends on your rib cage, tissue thickness, and goals.

    BOUNS

    BOUNS is offered in five projection profiles, from Low to High (models BRMS-L, BRMS-LP, BRMS-M, BRMS-MP, and BRMS-H), across base diameters of about 11.25 to 12.50cm, with volumes from about 200 to 425cc.

    Frequently Asked Questions

    How do I choose the right breast implant?
    Because each person's body conditions are different, including the rib cage, the thickness of the soft tissue, and the desired size, the right implant should be found through a detailed consultation with a specialist who judges from multiple angles. NANA offers BOUNS, Motiva, Mentor, and Sebbin implants and matches the type to the individual.
    Which implant suits a small rib cage or thin skin?
    Motiva is suited to those with a smaller rib cage or thin skin who want to lower the risk of rippling, want the shape to hold well, and prefer a lower chance of a foreign-body sensation or allergy. Sebbin is also suited to those with less breast tissue and thin skin who want a firm, elastic shape and a larger volume on a small rib cage, with safety as the top priority.
    Which implant is best for correcting asymmetry?
    Both Mentor and Sebbin are suited to those who want to correct asymmetry. Mentor suits those for whom feel is important, who want an implant from a trusted company with proven safety and a range of types. Sebbin suits those with less breast tissue and thin skin who want an ideal, elastic shape.
    How much will my bust size increase with an implant?
    Recently, many people choose an implant of about 250 to 300cc. In that case, the bust measurement increases by about 5 to 6cm after surgery, which is roughly 2 to 3 cup sizes. As a reference, an implant of about 100cc increases the bust measurement by about 2cm. Actual sizing can differ by individual body type.
    What are BOUNS and Motiva implants known for?
    BOUNS is a newer implant type that addresses drawbacks of earlier implants, suited to those for whom keeping the breast shape and the feel matter, and who want a range of sizes. Motiva, which received FDA approval in 2024, suits those with a smaller rib cage or thin skin who want to lower the risk of rippling, want the shape to hold well, and prefer a lower chance of foreign-body sensation or allergy.
    Are breast implants FDA approved?
    Among the implants offered at NANA, Motiva received FDA approval in 2024 and Mentor received FDA approval in 2017. Proven safety is one of the criteria used when matching an implant to each person.
    Do the implants come with a warranty?
    Several do. BOUNS has a dedicated warranty program supporting free implant replacement when its conditions are met. Motiva offers a warranty on Ergonomix with Q, covering re-operation for rupture or grade 3 to 4 capsular contracture within 5 years. Mentor promises a lifetime replacement policy across its full range when a re-operation is needed due to an implant problem. Coverage and terms vary by product and by the purpose of surgery, so details are confirmed at the clinic.
    How durable is the Motiva implant?
    The clinic reports a Motiva rupture rate below 1% over 10 years, described as among the lowest in the industry, and Motiva is designed for semi-permanent use, so no separate replacement is needed unless there is a specific problem. Durability still depends on the individual and on following aftercare.
