Restoring fat under the eyes is one of the most common requests in facial rejuvenation, and there are several proven ways to do it. The under-eye area (often called the tear trough) loses volume naturally with age, leaving a hollow, sunken look that can make you appear tired even when you’re well-rested. The main options for adding volume back include fat transfer from your own body, injectable fillers, and newer regenerative treatments that stimulate your skin to rebuild tissue on its own.
Why You Lose Volume Under Your Eyes
Your lower eyelid sits over three distinct fat pads that provide cushioning and fullness. Over time, these pads shrink as part of the normal aging process. The skin and connective tissue holding them in place also weaken, which can cause the remaining fat to either deflate or shift downward into visible bags. The result is a hollow groove between your lower eyelid and cheek that casts a shadow, creating the appearance of dark circles.
This isn’t purely an aging issue. Some people are genetically predisposed to thinner under-eye fat pads and notice hollowness in their twenties or thirties. Significant weight loss can accelerate the process, since the face loses fat along with the rest of the body. Bone resorption in the midface, where the skull gradually loses density over decades, also deepens the hollow by reducing the structural support underneath those fat pads.
Fat Transfer: Using Your Own Fat
Under-eye fat transfer is a surgical procedure that moves fat from one part of your body to the area beneath your eyes. A provider uses liposuction to harvest fat cells, typically from the belly, hips, or thighs. The harvested fat is then spun in a centrifuge to filter out impurities, and the purified fat cells are injected beneath your lower eyelids in small amounts using a very thin needle, placed in a grid-like pattern to create even distribution.
The key thing to understand about fat transfer is that your body reabsorbs a significant portion of the injected fat. Providers typically inject more volume than needed to compensate for this. Studies on facial fat grafting show volume retention rates ranging from about 33% to 65% after one year, meaning somewhere between a third and two-thirds of the transferred fat survives permanently. The wide range depends on technique, how the fat is processed, and individual biology. Some newer techniques that enrich the fat graft with stem cells from your own tissue have pushed retention rates toward the higher end of that range.
Because of the absorption factor, some people need a second touch-up procedure several months after the first to achieve their desired result. Once the surviving fat cells establish a blood supply in their new location, though, the results are long-lasting. Fat transfer is generally a one-time investment rather than an ongoing maintenance treatment.
What Recovery Looks Like
Expect noticeable swelling and bruising for the first one to two weeks, both under your eyes and at the liposuction site. The under-eye area will look overfilled initially, which is intentional. As swelling resolves and your body absorbs the excess fat, the volume settles into a more natural appearance. Most people return to normal activities within 7 to 14 days, though final results take three to six months to fully emerge as the surviving fat stabilizes.
Hyaluronic Acid Fillers
Injectable fillers are the most popular non-surgical option for restoring under-eye volume. The fillers used in this area are hyaluronic acid gels, a substance your body produces naturally. Common products include Restylane, Belotero Balance, Juvederm Volbella, and Juvederm Vollure. These are soft, low-density formulations chosen specifically because the under-eye skin is thin and unforgiving of lumps or irregularities.
The procedure takes about 15 to 30 minutes in an office setting with topical numbing. Results are visible immediately. The reported duration of effect averages around 10.8 months based on patient satisfaction, but objective imaging studies show measurable volume augmentation lasting an average of 14.4 months. A retrospective study published in the Journal of Clinical and Aesthetic Dermatology found that tear trough fillers offered significant results up to 18 months, with some patients still showing visible improvement at 24 months. This is considerably longer than fillers placed in more mobile areas of the face, likely because the under-eye area doesn’t move as much.
Fillers carry a meaningful advantage in reversibility. If you don’t like the result or develop a complication, hyaluronic acid can be dissolved with an enzyme injection. The downside is cost over time. Under-eye filler treatments typically require one to two syringes per session, and you’ll need repeat treatments every year or two to maintain volume. Over five years, that recurring expense often exceeds the one-time cost of fat transfer.
PRF: A Regenerative Approach
Platelet-rich fibrin, or PRF, takes a different approach. Rather than adding volume directly, it stimulates your body to rebuild tissue in the under-eye area. A small amount of your blood is drawn and processed to concentrate platelets, white blood cells, and a natural fibrin scaffold. This mixture is then injected under the eyes, where it releases growth factors slowly over several weeks.
Those growth factors trigger your skin to produce more collagen and elastin, gradually increasing skin thickness and quality in the treated area. PRF won’t create dramatic volume the way fat transfer or fillers can, but it improves the overall texture and density of thin under-eye skin. It works best for mild hollowing or as a complement to other treatments. Because improvements develop gradually through your body’s own repair processes, results take several weeks to become visible, and most people need a series of three to four sessions spaced a few weeks apart.
Comparing Cost and Longevity
The financial picture shifts significantly depending on your time horizon. Filler treatments cost roughly $700 to $1,500 per syringe, with most people needing one to two syringes for the under-eye area. That means $700 to $3,000 per session, repeated every 12 to 24 months. Over five years, you could spend $3,500 to $8,000 or more on maintenance alone.
Fat transfer costs more upfront, typically ranging from $5,000 to $12,000 depending on the extent of treatment and geographic location. Even with a potential touch-up procedure, the total five-year cost rarely exceeds $15,000 to $20,000, and much of that result is permanent. For someone planning to maintain their results long-term, fat transfer often becomes the more economical choice after the three- to five-year mark.
PRF sessions are generally less expensive per treatment than fillers, but the results are subtler and shorter-lived, making it a better fit for early or mild volume loss rather than significant hollowing.
Which Option Fits Your Situation
Your best option depends on how much volume you’ve lost and how you feel about surgery. For significant hollowing with deep tear troughs, fat transfer provides the most substantial and lasting correction. It requires anesthesia, a liposuction site, and a longer recovery, but you’re working with your own tissue and the results can last years.
For mild to moderate hollowness, or if you want to test what added volume looks like before committing to surgery, hyaluronic acid fillers are a lower-risk starting point. They’re reversible, require no downtime, and deliver immediate results. Many people start with fillers in their thirties or forties and transition to fat transfer later when they want a more permanent solution.
PRF works well as an early intervention or an add-on. If your concern is more about skin quality, mild darkening, and early thinning rather than a deep hollow, PRF can thicken and rejuvenate the skin without adding artificial volume. It pairs well with either fillers or fat transfer for a more comprehensive result.
