Silimed Breast Implants: Everything You Need to Know

Posted on [post_date] [post_comments] [post_edit]

When women research breast implants ahead of their , the conversation tends to centre on the two most recognised brands in the UK market. But there is a third name that experienced surgeons know well — and one that is increasingly sought out by patients who have done their research. Silimed is a Brazilian-founded implant manufacturer with over 45 years of history, a CE Mark for European use, and a body of clinical evidence that positions it as a serious alternative to the more widely marketed options.

At Centre for Surgery, we believe patients deserve complete, honest information about every implant option available to them. In this guide, we cover everything you need to know about Silimed breast implants — their history, product range, surface technologies, safety profile, warranty programme, and how they compare to other leading brands on the market. If you are considering in London and want to understand whether Silimed is the right implant choice for you, read on.

Who Are Silimed?

Silimed — formally Silimed Indústria de Implantes Ltda — was founded in Brazil in 1978 and has grown to become the largest manufacturer of silicone gel implants in Latin America. Over more than four decades, the company has developed a reputation for manufacturing innovation, particularly in the area of implant surface technology, and for producing a more extensive range of surface options than any other implant manufacturer in the world.

Silimed implants carry the CE Mark for European use, confirming they meet the regulatory standards required for use in the UK and across Europe. They are also FDA-approved for the North American market — Silimed became the first manufacturer in the world to receive FDA approval for anatomical and round silicone implants coated with True Texture, their proprietary micro-textured surface, in 2012. Their implants are distributed in numerous countries and are used by plastic surgeons worldwide.

The Silimed Breast Implant Range

Silimed offers two main product lines for breast augmentation: the BioDesign Line and the Standard Line. Each addresses a different set of patient needs and surgical goals.

The BioDesign Line is Silimed’s flagship innovation — a range of implants with an exclusive design concept built around female biotypes rather than fixed volume categories. The philosophy behind is that the most natural result comes from matching the implant’s measurements to the patient’s individual chest dimensions, rather than simply selecting a volume. The range offers five distinct profiles, each developed for a different body type, and up to four projection options per profile — covering anatomical (teardrop) implants, round implants, and the conical Advance implant, which is exclusive to the European market.

The five BioDesign profiles specific chest anatomies. Some are to fill the lower pole of the breast for women with shorter, wider chests. Others focus on upper pole projection for taller women with longer, narrower chest dimensions. This biotype-led approach allows surgeons to achieve tailored results rather than approximating fit from a standard catalogue.

The Line offers a round implant option designed for versatility across a wide range of indications. It is well-suited to seeking a more pronounced, fuller result with upper pole projection, and can be used across subglandular, submuscular, and dual plane placements. It is also suitable for primary reconstruction cases.

Soft Plus is a round implant developed as an evolution of the classic smooth surface, incorporating Silimed’s HSC+ high-strength cohesive gel with the BioDesign concept of projection-matched sizing. Like the BioDesign range, it offers different projections for each base size, allowing the desired projection to be achieved without unnecessarily increasing volume — a key consideration for patients seeking a more natural and proportionate outcome. The Soft Plus surface has an opaque smooth finish with an arithmetic roughness of approximately 5 micrometres.

Silimed’s Four Implant Surfaces

One of Silimed’s most significant differentiators in the global implant market is that it is the only breast implant manufacturer in the world to offer four distinct surface options. The choice of surface has a direct bearing on outcomes including rates, implant stability, and the risk of rotation — so understanding what each surface offers is important when making an informed decision about implants.

Silimed has been manufacturing polyurethane foam-coated implants for over 35 years — longer than any other manufacturer — giving it unmatched clinical experience with this surface type. The polyurethane coating adheres to surrounding tissue through a process called vulcanisation, with no use of adhesive, which avoids the risk of double capsule . The adhesion also significantly reduces the risk of implant rotation and displacement, making polyurethane-coated implants particularly appropriate for patients with ptosis or those where implant positional stability is a concern. Clinical data reports a rate of just 1% over ten years with Pure Polyurethane implants — one of the lowest rates documented for any implant surface.

True Texture is Silimed’s proprietary micro-textured surface, produced using a unique Diffusion Gas Method that creates an open-pore membrane structure without the use of negative imprinting, sugar, or sodium chloride. This manufacturing method is entirely Silimed’s own and results in a surface with a consistently low rate of 9% over ten years. True Texture is available on both and round implants within the BioDesign range and was the first textured surface of its kind to receive FDA approval for both shapes.

The Soft Plus surface is a smooth surface with a very fine arithmetic roughness of approximately 5 micrometres — sitting between a truly smooth implant and a micro-textured one. It is the surface used on the Soft Plus round implant range and is particularly suited to patients seeking upper pole fullness with a more prominent projection in a primary augmentation or reconstruction setting.

Silimed also produces implants with a smooth surface for cases where this is the most clinically appropriate choice. Smooth implants move more freely within the breast pocket and are associated with a softer, more natural feel for many patients.

The Silimed HSC+ Gel

All Silimed implants are filled with their proprietary HSC or HSC+ high-strength cohesive silicone gel — a formulation that has been in clinical use for many years and has an extensive safety record. The gel is designed to closely mimic the feel and movement of breast tissue, while maintaining the structural integrity that prevents migration in the event of implant rupture. The consistency of the gel varies slightly across different implant types to optimise the characteristics most relevant to each design — firmer in implants designed for pronounced projection and upper pole fullness, softer in those designed for the most natural movement and feel.

Silimed Safety and Clinical Evidence

The safety profile of Silimed implants is supported by substantial evidence accumulated over more than four decades of use worldwide. Key points from the clinical record include the following.

A prospective postmarket study of Silimed polyurethane foam-coated implants, covering 342 patients over a five-year follow-up period, reported zero cases of and zero implant ruptures. The reoperation rate over this period was 1.76%, with high patient satisfaction scores — 88.69% for primary augmentation and 86% for revision cases. Crucially, no cases of Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL) were identified in this cohort, supporting the safety profile of Silimed’s polyurethane surface technology in particular.

Ten-year core study data for the Silimed-Sientra HSC and HSC+ range — the same silicone gel used in Silimed implants — confirmed an safe rupture profile and demonstrated performance superior to other manufacturers reviewed in the same period. This body of evidence gives both surgeons and patients a high degree of confidence in the long-term durability of Silimed implants.

All Silimed products are manufactured to ISO — the internationally recognised quality management standard for medical devices — and the company operates under Good Manufacturing Practice (GMP) standards. You can read more about general implant safety considerations in our guide on .

Silimed’s Product Replacement Programme (PSPS)

Silimed offers a Product Replacement Programme — known as the PSPS — which implant replacement cover in the event of rupture due to a manufacturing defect, or Baker grade III or IV . For UK patients, the includes lifetime replacement cover for proven rupture due to a manufacturing defect, as well as up to £1,000 in assistance for implant caused by defects. Cover for capsular contracture extends to ten years for True Texture surface implants and Pure Polyurethane implants placed since May 2017.

It is worth noting that the PSPS covers the product replacement only and does not include surgical fees, anaesthesia, or hospital costs. Patients should also be aware that the programme requires adherence to Silimed’s guidelines and that implants should be registered following surgery — though registration is not mandatory for the warranty to apply.

How Do Silimed Implants Compare to Other Brands?

The premium breast implant market features several well-established brands, each with distinct strengths. Understanding how Silimed fits within this landscape helps patients make a more informed decision.

Many other brands offer either two or three surface options. Silimed’s offer of four distinct — including polyurethane foam coating with the longest clinical track record and lowest published rates of any surface type available — is a genuine differentiator. The BioDesign range’s biotype-matched sizing approach also represents a genuinely different philosophy to implant selection, one that surgeons find clinically useful for achieving highly tailored results. For patients where capsular contracture risk is a primary concern, or where fit is complex, Silimed’s range offers options not available from other manufacturers.

Are Silimed Implants Right for You?

Whether Silimed implants are the right choice depends on your anatomy, your aesthetic goals, and any specific risk factors relevant to your individual case. There is no single implant brand that is universally optimal for every patient — the best implant is the one that most closely matches the surgical requirement at hand.

Patients who may particularly benefit from Silimed’s range include those with a higher baseline risk of , those who have experienced contracture with a previous augmentation, patients requiring revision surgery, and those whose chest dimensions are better served by the biotype-matched sizing of the BioDesign range. Silimed’s polyurethane surface implants are also by many to be the most effective option available for minimising the risk of implant rotation in anatomical cases.

As with all implant choices, the decision is best made during a face-to-face consultation where your surgeon can assess your tissue characteristics, chest dimensions, skin quality, and desired in person.
