Internal Bra Materials: GalaFLEX, TIGR Matrix, ADM or Your Own Tissue?

The internal bra is a technique, not a product. It is the surgical principle of building a supporting layer inside the breast so that a lift, an augmentation or a revision is held by structure rather than by skin, and four materials are used worldwide to build it: the patient’s own fascia and muscle, GalaFLEX, TIGR Matrix and ADM. Dr. Paulo Michels’ standard is the autologous version — built from your own tissue — performed at Elyzee Hospital in Abu Dhabi for patients from Dubai and across the UAE.

Patients now arrive at consultation asking for the internal bra by name, and often for a specific brand. Much of what circulates online blurs the two: a mesh is described as though it were the operation. This article explains what each material is, how it is placed, how long it lasts, its regulatory status, the complications reported with it and what it does to the cost — and then why Dr. Michels builds the Internal Bra from the patient’s own tissue as standard. Each option has a legitimate place in breast surgery, and this is not an argument that three of them are wrong.

Is the internal bra a product or a technique?

A technique. Every breast lift faces the same structural problem: the surgeon removes stretched skin, reshapes the gland and raises the nipple, and then the entire reshaped breast is held by the tightened skin envelope. Skin is not a structural material. It stretches again with gravity, time, weight change and pregnancy, which is why a lift held by skin alone gradually settles.

An internal bra transfers that load to a deeper, stronger layer — the way the band and underwire of a good bra carry weight from below, but built inside the breast and left there. What that layer is made of is a separate decision.

What exactly is GalaFLEX?

GalaFLEX is a surgical scaffold knitted from poly-4-hydroxybutyrate, usually shortened to P4HB — an absorbable synthetic polymer. It arrives as a sheet, is trimmed to shape and is sutured into the lower pole of the breast as a sling, or along the inframammary fold, through the same incision used for the lift or augmentation. No extra scars are created by the material itself.

Its behaviour over time is the point of it. The scaffold holds the reshaped tissue while healing takes place and resorbs over roughly 12 to 18 months, leaving behind a layer of the patient’s own collagen laid down along it. The intention is that this collagen, rather than the mesh, provides the lasting support. GalaFLEX is the scaffold patients have most often read about. It adds the cost of the device to the operation.

What is TIGR Matrix, and why is it called the most modern option?

TIGR Matrix is a fully synthetic, long-term resorbable mesh, and its design is genuinely more sophisticated than a single-fibre scaffold. It is knitted from two different fibres with two different resorption profiles. The fast-resorbing fibre gives the construct its strength through the first weeks, when the repair is most vulnerable. The slow-resorbing fibre continues to support the tissue for many months afterwards, then softens progressively and is fully absorbed over about three years.

The rationale is a gradual handover: the mesh gives up its load slowly, in step with the patient’s own collagen taking it on, instead of disappearing while the tissue is still adapting. It is placed exactly as GalaFLEX is — trimmed, positioned in the lower pole or at the fold, and sutured through the existing incision — and it too adds a device cost to the surgery.

What is ADM, and where does it belong?

ADM stands for acellular dermal matrix: a biological sheet of human or porcine dermis that has been processed to remove all cells, leaving the collagen framework behind. Because there are no cells, it is not rejected as foreign tissue; instead the patient’s own cells and blood vessels grow into it and it becomes incorporated.

ADM is the material with the strongest role outside cosmetic surgery. Its established use is in breast reconstruction after mastectomy, where it provides coverage for an implant when the native soft tissue is inadequate, and in complex revision where the tissue is genuinely too thin to hold a repair. It is the most expensive of the four options by a clear margin, and it carries its own reported issues — seroma and, characteristically, a red-breast reaction, an inflammatory redness over the graft that must be told apart from infection.

Why is Dr. Michels’ standard internal bra built from your own tissue?

The autologous internal bra uses no device at all. During a breast lift with or without implants, flaps of the fascia and muscle of the chest wall are raised and secured beneath the reshaped breast to form a hammock, and permanent internal sutures rebuild and reinforce the inframammary fold — the shelf on which the lower breast and, in augmentation, the implant rest. Both are created through the same incision as the operation itself.

The reasoning is biological rather than ideological. The sling is living tissue with its own blood supply, so it does not have to be integrated, tolerated or resorbed. It cannot be felt as a separate layer, it cannot become exposed through a wound, it cannot become infected as a foreign body, and it does not hand over its job to a collagen layer at some future date, because it is the tissue. It also adds no device cost.

What it requires is tissue worth building from. Where a patient’s own fascia is genuinely too thin — some very thin patients, some heavily operated revisions, some reconstructive situations — a scaffold is the better answer, and Dr. Michels says so rather than forcing an autologous solution onto anatomy that cannot supply it.

Are any of these materials approved for a cosmetic breast lift?

This deserves a plain answer. GalaFLEX, TIGR Matrix and ADM are cleared for soft-tissue reinforcement in general terms, but no mesh or matrix is specifically approved for cosmetic breast lift or augmentation, and their use in aesthetic breast surgery is regarded as off-label in most jurisdictions.

Off-label is a regulatory description, not an accusation. Well-established practice in many fields of medicine is off-label, and experienced surgeons use these materials thoughtfully and publish their results. What matters is that you are told, in advance, that a device is being placed in your breast, which device it is, that its use in this setting is off-label, what it is expected to do and what happens if it does not.

Who actually needs an internal bra at all?

Not everyone, and it is worth saying so before choosing between materials. Internal support earns its place where the tissue is least able to hold a lift by itself: grade 2 to 3 sagging with the nipple at or below the fold, thin or inelastic skin after pregnancy or major weight loss, heavy breasts, larger implants or a soft fold that would let an implant descend, revision cases where a previous lift settled early, and lifts after implant removal, where the breast has been stretched by an implant for years.

In a younger patient with good skin elasticity, a modest breast and mild sagging, a well-performed lift holds well on its own. If that describes you, the honest answer at consultation is that the internal bra adds comparatively little — and if you are also deciding between a lift and implants in the first place, the comparison of what a lift and implants each fix is the more useful starting point.

When should I contact the surgeon after surgery?

Whatever the internal bra is built from, the early warning signs are the same, and all of them are things you can see or feel:

• A breast that becomes progressively larger, tighter or heavier over hours rather than days
• Redness spreading across the skin, or skin that is hot to the touch
• Fever, chills or feeling unwell
• Fluid or discharge from an incision, or an incision edge that opens
• A wound that has not closed as expected by the second week
• Pain that increases after the first few days instead of steadily improving

None of these are reasons to wait for the next scheduled appointment. Where a scaffold has been placed, an opening wound over the material matters more, because exposed mesh may need to be removed — one more reason to know exactly what was implanted in you.

How are patients from Dubai seen for this in Abu Dhabi?

Consultations and surgery take place at Elyzee Hospital in Abu Dhabi, roughly an hour’s drive from Dubai, and visits are grouped so that patients travelling in are not asked to make the trip more often than necessary. At the consultation Dr. Michels grades the degree of sagging by the nipple’s position relative to the fold, assesses skin quality and thickness, measures the chest and uses 3D simulation to show the expected shape on your own body. Whether an internal bra is included, and what it should be built from, is decided from that examination and explained plainly — including, if a scaffold is genuinely the better choice for your tissue, its off-label status and its cost. Patients based in Dubai can read how breast lift consultations are arranged for them before booking.
