Eye hollows, often called tear troughs, form when the area beneath your lower eyelids loses volume, creating a shadowed groove that runs from the inner corner of your eye toward your cheek. Fixing them ranges from simple topical care to injectable fillers to surgery, depending on how deep the hollowing is and how long you want results to last.
Why Eye Hollows Form
The under-eye area is one of the thinnest skin zones on your body, with very little fat cushioning it. Beneath that skin sits a layered structure of muscle, ligaments, fat pads, and bone. As you age, several things happen at once: the fat pads shrink and slide downward, the ligaments holding everything in place stretch out, and the cheekbone itself gradually resorbs. The combined effect is a visible groove where the lower eyelid meets the cheek.
Genetics play a significant role too. People with a more prominent cheekbone can develop a larger gap between the bone and skin in the tear trough area, which means less structural support for the soft tissue above it. This is why some people notice hollowing in their twenties while others don’t see it until their forties or fifties. Weight loss, dehydration, and chronic sleep deprivation can also make existing hollows look worse by further thinning the fat layer and darkening the skin.
Injectable Fillers: The Most Common Fix
Hyaluronic acid fillers are the go-to treatment for under-eye hollows. Brands like Restylane, Belotero, and Juvederm are all used in this area. No filler is currently FDA-approved specifically for the under-eye region, so all tear trough injections are considered off-label use. That said, hyaluronic acid fillers are preferred here because they’re transparent, easy to smooth into place, and less likely to clump than other filler types.
A single session typically takes 15 to 30 minutes. Results are visible almost immediately and last approximately 9 to 18 months for most people. Many patients schedule maintenance treatments every 12 to 18 months. Cost runs between $684 and $1,500, since the average price for a syringe of hyaluronic acid filler is around $684 and some patients need more than one.
Risks to Know About
The most common cosmetic complication is the Tyndall effect, a bluish or grayish tint that shows through the skin when filler is placed too close to the surface. It happens because light scatters off the gel and reflects blue wavelengths back. It’s not dangerous, but it is visible and can be frustrating. The fix involves dissolving the filler with an enzyme injection, which resolves the discoloration quickly, often within a day, though temporary swelling is common afterward.
More serious but rare risks include filler migrating from the injection site and, in very uncommon cases, vascular occlusion, where filler blocks a blood vessel. Choosing an experienced injector who understands the complex anatomy of the under-eye area significantly reduces these risks.
Platelet-Rich Fibrin Injections
PRF (platelet-rich fibrin) is a newer option that uses a concentrated solution made from your own blood. A small blood draw is processed to isolate growth factors and healing components, which are then injected beneath the eyes. These growth factors stimulate collagen production and improve the thickness and opacity of the thin under-eye skin, making dark blood vessels less visible through the surface.
PRF releases its growth factors slowly, which promotes longer-lasting cellular regeneration compared to its predecessor, PRP (platelet-rich plasma). The trade-off is that results develop gradually over weeks rather than appearing immediately, and most people need a series of treatments. PRF works best for mild to moderate hollowing and is often combined with other treatments for deeper volume loss.
Surgical Options for Deeper Hollows
When hollowing is severe or accompanied by puffy lower eyelid bags, surgery offers the most lasting correction. The key procedure is lower blepharoplasty with fat repositioning. Rather than simply removing the fat pads that create under-eye bags, the surgeon relocates them, draping the existing fat over the orbital rim to fill the hollow groove. This addresses both the puffiness above and the shadow below in a single procedure.
Fat grafting is another surgical approach. Fat is harvested from elsewhere on your body (typically the abdomen or thighs) and injected beneath the eyes. One important finding from long-term research: a five-year follow-up study found that volume retention after fat grafting was related to overall weight changes rather than how much fat was initially injected. People who gained weight retained more volume, and those who lost weight saw more diminished results. This makes fat grafting somewhat less predictable than other methods.
What Recovery Looks Like
Surgical recovery follows a fairly consistent pattern. Days one through three bring the most intense swelling and bruising, with swelling peaking around day two. By days four through seven, the tightness eases noticeably and stitches come out, usually between days five and seven. Most visible bruising clears by weeks two to three, and the eyelids start feeling more natural. Residual swelling becomes minimal by weeks four to six, with scars beginning to fade. Most remaining swelling resolves within two to three months, but full healing and scar maturation takes six to twelve months.
Plan on at least one to two weeks before you’ll feel comfortable in social settings without concealer, and avoid strenuous exercise for several weeks.
What Topical Products Can (and Can’t) Do
No cream or serum will restore lost volume beneath the eyes. That’s the honest limitation of topical products. However, they can improve the appearance of the area by thickening the skin slightly and reducing the visibility of the hollow.
Hyaluronic acid applied topically has the strongest evidence in this area. Studies show that twice-daily application of low-molecular-weight hyaluronic acid for 60 days significantly decreased wrinkle depth in the periorbital region and improved moisture and elasticity. The effect comes from hyaluronic acid’s ability to bind water and reduce the breakdown of collagen and elastin in the skin. Certain peptides have also shown measurable wrinkle-depth improvement in controlled studies when applied consistently for several weeks.
One interesting development is polymer-based under-eye films that cross-link on the skin’s surface after application. A randomized study found this technology produced a one-grade improvement in lower lid bag protrusion and increased skin thickness. These products won’t erase a deep tear trough, but they can soften its appearance for a night out or as part of a daily routine while you decide on a more permanent option.
Choosing the Right Approach
The best fix depends on the severity of your hollowing and your tolerance for downtime, cost, and maintenance. For mild hollows that mostly bother you in certain lighting, topical hyaluronic acid and good hydration habits can make a visible difference over a couple of months. Moderate hollowing responds well to filler injections or PRF, with fillers offering immediate results and PRF offering a more gradual, natural-tissue approach. Deep hollowing with excess skin or prominent bags is best addressed surgically, where fat repositioning provides the most durable correction.
Age matters less than anatomy. A 30-year-old with genetically thin under-eye skin and prominent bone structure may benefit from fillers just as much as a 55-year-old with age-related volume loss. The deciding factors are how much volume has been lost, the quality of the overlying skin, and how much the appearance affects your daily life.
