She is in the bathroom trying to get comfortable, three days post-BBL, and she is wearing a faja. What nobody told her is that the standard faja she was given at the surgery centre is pressing firmly against the exact area where the fat was transferred. The garment that is supposed to help her heal is compressing the grafts.
This is the most common garment mistake in BBL recovery. It is also entirely avoidable if you know what to look for before you get to that point. A BBL compression garment is not the same as a standard lipo faja, and the difference is not aesthetic. It is structural, and it matters for your outcome.

The short answer
A BBL compression garment must have a full open-back or open-seat design that leaves the buttocks pressure-free while compressing the donor sites. A standard lipo garment compresses everything, including the grafts. The open-seat design is not optional. It is the defining requirement of a BBL-specific faja.
Why BBL Compression Is Categorically Different
Standard liposuction compression works on one principle: apply even pressure across all treated areas to reduce swelling and support skin retraction as the body heals. That logic is correct for standard lipo. After a BBL, that logic becomes actively harmful if applied to the wrong area.
A BBL transfers fat cells from donor sites (abdomen, flanks, thighs, back) into the buttocks. The donor sites need compression. The recipient site (buttocks) must not be compressed during the fat graft survival window, because the transferred fat cells need an uninterrupted blood supply to establish themselves. Compression interferes with that. According to Beshapy’s BBL recovery kit guide and Colombiana Boutique’s faja specifications, a BBL faja is specifically engineered to compress and support the liposuction donor sites while completely avoiding pressure on newly transferred fat cells in the buttocks.
A standard faja worn over the full body compresses both the donor sites and the buttocks. This is what must be avoided. The solution is an open-back or open-seat design: compression applied only to the donor sites, with the buttock area entirely pressure-free.
For a full picture of how garment requirements change across the recovery timeline, the BBL recovery timeline breaks down exactly what to expect at each stage, including when compression rules evolve.
What to Look For: The Non-Negotiables
The first and only non-negotiable is a full open-back or open-seat design. Not a small decorative cutout. Not a panel with strategic thinning. A true, full opening over the entire buttock area, such that when you sit upright on a BBL pillow and look down, no compressive fabric is in contact with the graft area. That is the test. If fabric touches the buttocks while sitting properly supported, the garment is not a BBL garment regardless of what it says on the label.
Beyond the open seat, the garment should cover all donor sites used in your specific procedure. This typically means the abdomen, waist, and flanks at minimum. If thighs or back were donor areas, the garment needs to extend to cover those regions. Hook-and-eye or zipper closures are preferable to pull-on designs because swelling reduces significantly over the first six weeks, and you need to be able to adjust compression accordingly without purchasing a new garment.
Medical-grade compression rather than shapewear-grade. This distinction matters. Shapewear is designed for aesthetics in normal tissue. Medical compression is calibrated for healing tissue. The two are not interchangeable regardless of how a product is marketed.

Stage 1 vs Stage 2 for BBL: The Same Logic, the Same Open-Seat Requirement
Stage 1 fajas are medical-grade compression garments worn during the first 4-6 weeks of recovery. For BBL, the open-seat requirement applies at Stage 1 without exception. According to Colombiana Boutique and consistent clinical BBL sources, Stage 1 fajas are worn continuously for the first six weeks, removing only to shower.
Stage 2 begins from approximately week 6 onward, as swelling reduces and the body starts to show its final shape. Stage 2 garments are generally lighter compression and focus more on shaping than on acute support. Some brands offer BBL-specific Stage 2 garments with lifting panels that contour the buttock area from outside without applying direct compression to the graft zone. These are appropriate after the fat has established blood supply, typically from week 6-8 with explicit surgeon clearance.
The open-seat requirement does not disappear at Stage 2. Until your surgeon specifically clears you from the sitting restriction and confirms graft survival, no compressive fabric should contact the buttocks.

According to Carely Clinic’s BBL compression garment guide, wear the garment 24 hours per day for the first six weeks, removing only to shower. From weeks 7 through 12, this reduces to approximately 12 hours daily. This schedule is not arbitrary. Consistent compression supports swelling reduction and skin retraction. Inconsistent wear produces inconsistent results.
Wash the garment every 1-2 days with mild detergent, by hand. Never use a machine dryer. Heat and tumbling distort the compression structure in ways that make the garment effectively useless. Air dry flat. Because the garment needs daily washing, having a second garment in rotation is not a luxury. It is a practical necessity.
Compression marks on the abdomen and flanks after garment removal are normal and typically fade within an hour. Marks persisting longer than a few hours may indicate the garment is too tight at that point in recovery. As swelling reduces, adjust the closures or move to Stage 2.
What Does Not Work (and a Test to Catch It)
Regular shapewear is not a substitute. Regular compression shorts or leggings compress the buttocks. Even light compression over the graft area in the first six weeks can affect fat survival. This is not a preference issue. It is a clinical requirement, and it applies even to garments marketed as “gentle” or “light hold.”
Some brands market garments as “BBL compression” that are effectively standard fajas with minimal or insufficient buttock openings. The decorative cutout problem is real: a small oval or keyhole opening may look open-seated but still makes contact with significant parts of the buttock when the patient is sitting upright. The only valid test is sitting on a BBL pillow, upright, in the actual garment. If any compressive fabric touches the buttocks, the garment is wrong for this purpose.
Patients who develop fat loss in the grafted area despite following sitting restrictions are often found to have been wearing inadequate garments with insufficient buttock openings. The sitting restriction and the open-seat garment work together. Neither is sufficient without the other.
This is normal with correct garment use
Compression marks on the abdomen and flanks that fade within an hour of garment removal
The buttock area feeling uncovered or exposed — this is correct
Garment feeling looser over weeks 2-4 as swelling reduces — size down or tighten closures
Mild skin irritation at garment edges in the first week
Check your garment if
You feel compression or fabric contact on the buttocks when sitting upright on a BBL pillow
The garment has a small decorative cutout rather than a full seat opening
You were given a standard lipo garment at your surgery centre without a specific open-seat design
Skin breakdown is occurring where the garment contacts donor site areas
Frequently Asked Questions
Can I use a regular lipo faja if it is a size larger so it does not press on the buttocks?
No. Sizing up a standard faja does not create the structural open-seat design that a BBL garment requires. A larger standard faja will still make contact with the buttock area when the patient sits, often pulling or gapping in ways that create intermittent rather than absent pressure. The open-seat design requires a specifically engineered opening, not a looser version of the wrong garment shape.
When does the open-seat requirement end?
The sitting restriction, and the garment requirement that comes with it, typically applies for 4-8 weeks, according to Colombiana Boutique and consistent with American Society of Plastic Surgeons guidelines on fat graft survival. Your surgeon will confirm when the grafts have established blood supply and when normal seating pressure becomes acceptable. Until that clearance, the open-seat garment is required.
What if my surgery centre provided a standard compression garment?
Some surgery centres, particularly those offering bundled procedure packages, provide standard lipo compression garments that are not appropriate for BBL recovery. If the garment you received does not have a full open-seat design, contact your surgeon’s office to confirm the specific requirement and source a BBL-appropriate garment before your recovery progresses beyond the first day or two.
The compression schedule aligns closely with the exercise restrictions that run alongside the compression schedule, and understanding both together gives a clearer picture of the full recovery arc.
