The popularity of GLP-1 medications, including tirzepatide and semaglutide, continues to be on the rise. (1) While the health benefits of medically-assisted weight loss are numerous, many patients experience the unwelcome side effect of loose skin and loss of volume in desirable areas like the buttocks. Often, these individuals require surgical intervention to restore optimal contours—these concerns are often beyond what a healthy diet and exercise can improve.

At Austin Plastic Surgeon, our team of experts is dedicated to educating post-weight-loss patients on their options, ensuring they look and feel their best through specialized body contouring techniques.

We offer a range of highly effective surgical and nonsurgical options for restoring volume and shape to the buttocks. alloClae offers a non-surgical solution using purified donor fat to create natural volume without requiring a fat transfer. Meanwhile, a traditional Brazilian Butt Lift (BBL) is a surgical procedure that uses the patient’s own harvested fat to significantly enhance the size and shape of the buttocks.

The choice between these aesthetic approaches is a personal one, and the highly trained surgeons and specialists at Austin Plastic Surgeon are passionate about helping each patient find the right treatment for them.

About Volume Augmentation After Weight Loss

Patients want to celebrate their triumph after a successful weight loss journey, yet the results often bring a new set of aesthetic challenges. When we lose a large amount of weight rapidly, the skin may not have the elasticity it needs to snap back into place, so it sags instead. Critically for the buttocks, the dramatic reduction in overall body fat means the loss of natural volume and projection in this area. This loss of contour can be disheartening after all the hard work patients put into their weight loss journey.

Our post-weight-loss body contouring procedures specifically address these concerns, going beyond simple volume replacement. They aim to restore the harmonious curves and youthful shape of the buttocks.

alloClae vs Fat Transfer

The decision between a less invasive procedure for more subtle enhancement and a surgical approach for more significant change is a critical aspect of any patient’s post-weight-loss transformation plan. Understanding the mechanisms of each procedure is the first step in determining the right path for you.

alloclae

alloClae is an off-the-shelf filler specifically designed for the body. Its extracellular matrix and adipocyte membranes add volume to the targeted area immediately and promote regeneration over time. (2) Our specialists perform this treatment in-office, which involves a series of injections and requires no general anesthesia or significant downtime. It is an excellent choice for individuals seeking subtle enhancement, a modest lift, a smoother contour, or an improvement in skin quality that often worsens from volume loss.

This works best for those who would like to achieve a small to moderate amount of volume replacement and primarily desire a non-surgical boost. Because alloClae does not require the fat transfer process, it is especially great for patients who are on the thinner side, who may not have enough excess fat to qualify them for liposuction. alloClae’s unique composition of 60% adipocyte membranes and 40% extracellular matrix provides a scaffold for your own cells to proliferate, supporting collagen production and tissue remodeling for natural-feeling and long-lasting results.

alloClae has given patients options when in the past they had none. So many of our patients feel absolutely incredible after their weight loss journey. However, they want to restore the volume they lost in their buttock, but don’t have any fat to transfer. They have what many people refer to as Ozempic Butt. The loss of volume after their weight loss journey on GLP-1 medications. Alloclae is the solution for patients who previously had none!

Fat Transfer

A fat transfer to the buttocks, also known as a BBL, is a two-part surgical procedure. First, your surgeon harvests fat from other areas of the body (such as the abdomen, flanks, back, arms, or thighs) via liposuction. Second, they meticulously inject this purified, autologous fat into the buttocks to sculpt and enhance volume. Because it uses the patient’s own tissue, the results are incredibly natural, and a significant amount of the fat transferred typically survives (3) and provides lasting volume enhancement. The combination of liposculpting and the targeted fat transfer creates a powerful transformation as the reduction and shaping of the waist, plus the fat transfer, can create an incredible shape. The BBL is ideal for patients who require a significant increase in volume and projection, desire a dramatic change in shape, and are willing to undergo surgery and its subsequent downtime. One of the key considerations here is that the patient must have sufficient donor fat available to transfer, so thinner patients may not qualify for this procedure.

Ozempic Butt and BBL

The growing prevalence of GLP-1 usage has led to the term “Ozempic Butt” becoming part of our cultural vernacular. “Ozempic Butt” refers to the appearance of depleted volume and accentuated skin laxity in the gluteal area following significant weight loss. While the medications are effective for weight loss, rapid fat loss can disproportionately affect areas like the face and buttocks, leaving patients with a deflated or sagging appearance.

For patients experiencing Ozempic Butt, the candidacy for BBL versus alloClae becomes even more complex. If the patient has lost significant volume but still retains some pockets of excess fat in other areas (the “donor” sites), a BBL may be the ideal choice for comprehensive restoration and permanent results. The BBL not only restores gluteal volume but also improves the overall contour by removing fat from undesirable areas, creating a more dramatic figure.

However, if the rapid weight loss has left the patient with minimal body fat, meaning they are now quite lean and do not have sufficient fat for a BBL or skinny BBL, they may have to look for other options, such as alloClae. alloClae becomes an incredible option, and often the only option for volume replacement for our patients after their weight loss journey. The processed fat filler provides a way to restore contour, volume, and enhance the deflated skin without requiring the patient to have a supply of fat for liposuction.

The Right Choice for You

Choosing the right procedure means understanding the unique benefits of each and how they cater to your post-weight-loss concerns. The primary benefit of a BBL with fat transfer is the total transformation. The liposculpting enhances the overall figure while supplying fat to treat your Ozempic butt. It is a total body contouring procedure. It is a surgical procedure that can provide a significant, transformative increase in gluteal volume, projection, and shape change. Furthermore, the combination of liposuction and fat transfer allows for more comprehensive body contouring, creating ideal proportions by sculpting areas like the waist, back, or flanks while enhancing the buttocks. Because of the nature of this procedure, potential patients must possess sufficient, harvestable donor fat and be willing to commit to a post-surgery recovery protocol, which includes several weeks of physical restrictions.

A major benefit of alloClae is that it is a nonsurgical procedure that avoids general anesthesia and significant downtime. It is appealing for patients who wish to avoid surgery and only desire a subtle enhancement or volume improvement, or those who lack sufficient donor fat for fat transfer. Contouring procedures like the BBL can be very powerful in transforming your shape, but many patients don’t have any fat available for the procedure. AlloClae integrates seamlessly into the patient’s own cellular infrastructure, delivering a gradual, stable approach to volume restoration.

Personal Consultation

A personal consultation is essential for helping you choose the right body contouring treatment plan. Here, one of our surgeons will conduct a thorough physical examination, assess skin quality, evaluate the buttocks or other areas targeted for volume enhancement, and determine the availability of donor fat. Discussing your goals provides your surgeon with critical information to help them create your personalized treatment plan, which should align with your unique anatomy, lifestyle, and aesthetic vision.

Results

The most rewarding part of post-weight-loss body contouring is seeing the transformation. Results from an alloClae procedure are subtle and appear over time. Patients report an immediate result with minimal downtime or bruising and stable volume over the next few months to years. The result is a natural-feeling, youthful contour without the impact of surgery.

BBL results are substantial and dramatic in most people. Once the initial swelling subsides (which can take several weeks), the new shape of the buttocks and the sculpted surrounding areas become apparent. Patients often feel a profound boost in self-confidence, finding that their clothes fit better and their overall body proportions are more harmonious. The final, stable result typically appears at six months once the transferred fat has fully established its blood supply. Both procedures aim to finalize the patient’s weight loss journey with an aesthetic outcome that matches their tremendous effort.
