Hip augmentation is a cosmetic procedure that adds volume and shape to the hip area, typically to create a curvier silhouette or fill in “hip dips,” the natural indentations between the hip bone and upper thigh. It can be done surgically with fat grafting or silicone implants, or non-surgically with injectable fillers. The right approach depends on how much volume you want, how long you want it to last, and whether you’re willing to go through surgery and recovery.
Surgical vs. Non-Surgical Options
Hip augmentation falls into two broad categories. Surgical options include fat transfer (sometimes grouped with the Brazilian butt lift family of procedures) and silicone implants. Non-surgical options rely on injectable fillers to gradually build volume without an operating room.
Fat transfer, also called fat grafting, involves removing fat from another part of your body through liposuction, processing it, and then reinjecting it into the hip area. This is the most popular surgical route because it uses your own tissue, which lowers the risk of your body rejecting the material. The tradeoff is that not all transferred fat survives. Clinical studies report retention rates ranging from 30% to 70%, meaning a significant portion of the injected fat is reabsorbed by the body over the following months. Many people need more than one session to reach their goal.
Silicone implants are solid, shaped inserts placed beneath the skin and muscle layers around the hip. They deliver more predictable volume than fat transfer since there’s no reabsorption to account for, but they carry the risks that come with any implant: potential shifting, capsule formation (where scar tissue hardens around the implant), and the possibility of revision surgery down the line.
How Non-Surgical Fillers Work
The most common non-surgical approach uses an injectable filler that stimulates your body’s own collagen production rather than simply filling space. These fillers are injected directly into the hip dip area in a series of office visits. Because the hips are a large area, the volume of product required is substantial compared to facial injections. A full correction typically requires 20 to 30 vials spread across roughly three sessions, with 8 to 10 vials used per appointment.
Results aren’t immediate. The filler works by triggering collagen growth over time, so the visible change usually appears four to six weeks after treatment. Once results develop, they can last up to two years before the body gradually breaks down the material and volume fades. At that point, maintenance sessions are needed to preserve the look.
The appeal of fillers is obvious: no general anesthesia, no major incisions, and minimal downtime. But the cost of repeated sessions adds up quickly, and the results are more subtle than what surgery can achieve. For someone looking for a dramatic change in hip width or projection, fillers alone may not deliver enough volume.
What Happens During Surgical Hip Augmentation
For fat transfer procedures, the surgeon starts with liposuction on a donor site, commonly the abdomen, flanks, or inner thighs. The harvested fat is purified and then carefully injected in thin layers throughout the hip area. Layering the fat in small amounts helps maximize blood supply to the transferred cells, which improves how much fat survives long term. The entire process typically takes two to four hours depending on how much fat is being moved.
For implant-based augmentation, the surgeon creates a pocket in the tissue layers around the hip to house the implant. Placement can vary: some surgeons position implants above the muscle fascia (the tough connective tissue covering the muscle), while others place them beneath it for a more natural look and better coverage. The incision is usually made in a location that can be hidden by underwear or a bikini line.
Both surgical approaches use either general anesthesia or regional anesthesia (a spinal or epidural block that numbs you from the waist down while you remain sedated). Regional anesthesia is increasingly preferred for lower-body procedures because it allows for better pain control in the hours immediately after surgery.
Recovery After Surgery
The first two weeks are the most restrictive. Swelling and bruising are significant, and most surgeons require a compression garment to control fluid buildup and support the new contour as it heals. Sitting and lying directly on the hips may be limited, especially after fat transfer, since pressure can compromise blood flow to the newly grafted fat cells.
If you have a desk job, plan for about two weeks off work. Physically demanding jobs require closer to six weeks. Light walking is encouraged early to promote circulation, but high-impact exercise, swimming, and contact sports are off the table for roughly six weeks until incisions fully close and internal healing is well underway.
Swelling distorts your results initially. The shape you see in the first few weeks is not the final outcome. With fat transfer, the reabsorption process plays out over three to six months, so your final volume won’t be apparent until then. With implants, swelling typically resolves faster, but the tissue needs time to settle around the implant before the shape looks natural.
Risks and Complications
Seroma, a pocket of fluid that collects under the skin near the surgical site, is one of the more common complications after any procedure involving tissue disruption. In some cases these fluid collections resolve on their own; in others, they need to be drained with a needle in a follow-up visit. Implant loss due to seroma has been reported in 2% to 8% of cases across implant-based procedures.
Fat transfer carries its own set of concerns. Fat necrosis occurs when some of the transferred fat cells die and form firm lumps under the skin. These are usually harmless but can be uncomfortable or visible. Uneven absorption is another common issue: if fat survives unevenly across the two sides, the result can look asymmetric, sometimes requiring a touch-up procedure.
Infection, scarring, and nerve damage are possible with any surgical procedure. Implant-specific risks include shifting out of position over time and capsular contracture, where the scar tissue envelope around the implant tightens and distorts the shape. Some implant patients eventually need revision surgery to replace or reposition the implant.
How Long Results Last
Fat transfer results are considered semi-permanent. Once the surviving fat cells establish a blood supply in their new location, they behave like any other fat in your body, growing or shrinking with weight changes. The initial volume loss from reabsorption is the main limitation, which is why many surgeons slightly overfill the area during the procedure, anticipating that 30% to 70% of the volume will be lost.
Implants are the most permanent option, but “permanent” doesn’t mean maintenance-free. Implants can last many years, though their longevity in cosmetic hip procedures is less studied than in reconstructive joint surgery. Some patients go a decade or more without issues; others need revision sooner due to shifting, hardening, or changes in preference.
Non-surgical fillers are the least durable, with results fading over roughly two years. They’re a reasonable starting point if you want to preview a curvier hip shape before committing to surgery, but the ongoing cost of repeat treatments makes them the most expensive option over a long time horizon.
Who Gets Hip Augmentation
Most people seeking hip augmentation are looking to address hip dips, create a more hourglass-shaped figure, or restore volume lost through aging or weight loss. Candidates for fat transfer need enough donor fat to harvest, which means very lean individuals may not have sufficient material. In those cases, implants or fillers become the more practical choice.
Good candidates are generally at a stable weight, since significant weight fluctuations after the procedure can alter results. For fat transfer especially, gaining or losing a large amount of weight changes the volume of the transferred fat cells just as it would anywhere else on your body, potentially undoing the contouring effect.
