Sunken under eyes happen when the area beneath your lower eyelids loses volume, creating a hollow or shadowed appearance along what’s called the tear trough. The good news: several options exist to improve this, ranging from simple lifestyle changes and topical products to injectable fillers and surgery. What works best depends on how deep the hollowing is and what’s causing it.
Why Under Eyes Look Sunken
The skin beneath your eyes is some of the thinnest on your entire body, which is why this area shows volume loss before almost anywhere else. As you age, two things happen simultaneously: the fat pads that cushion your eye sockets shrink, and your body produces less collagen to keep that skin firm and supported. The result is eyes that appear to settle deeper into the sockets, with visible shadows or a bluish tint where blood vessels show through thinning skin.
Age isn’t the only factor. Extreme weight loss can make blood vessels below the eyes prominent and skin nearly transparent. Smoking accelerates collagen breakdown and degrades skin elasticity, which compounds the hollowing effect. Chronic dehydration pulls moisture from delicate facial tissue, making hollows temporarily worse. Deficiencies in iron, vitamin C, and vitamin E also affect skin and tissue health in this area, so poor nutrition can be a contributing factor that’s relatively easy to fix.
Genetics plays a major role too. Some people have naturally deeper-set eye sockets or less orbital fat from their twenties onward. If your parents had prominent tear troughs, you’re more likely to develop them regardless of lifestyle.
Topical Products That Can Help
Topical treatments won’t fill in deep hollows, but they can improve mild hollowing by hydrating, thickening, and firming the skin so it looks less transparent and sunken. The three ingredients with the most evidence behind them for this area are hyaluronic acid, retinol, and caffeine.
Hyaluronic acid is a moisture-binding molecule that plumps skin from the surface. It won’t add structural volume the way a filler does, but it reduces the papery, dehydrated look that makes hollows more visible. Retinol (a vitamin A derivative) stimulates collagen production over time, gradually thickening the skin so it doesn’t drape as loosely over the orbital bone. Results from retinol take weeks to months of consistent use. Caffeine constricts blood vessels temporarily, which can reduce the dark, bluish discoloration that accompanies sunken eyes and makes them look deeper than they are.
Eye creams and serums combining these ingredients are widely available. Look for products specifically formulated for the under-eye area, since the skin there is more sensitive than the rest of your face and can react to concentrations designed for thicker skin. Apply them gently with your ring finger (it naturally uses the least pressure) to avoid tugging on delicate tissue.
Lifestyle Changes Worth Trying First
Before spending money on procedures, a few straightforward habits can reduce the appearance of under-eye hollowing, especially if dehydration, sleep deprivation, or nutritional gaps are making it worse.
- Hydration: Dehydrated skin sinks and shadows more easily. Consistent water intake throughout the day keeps under-eye tissue from looking deflated.
- Sleep: During sleep, your body increases blood flow to the skin and ramps up collagen repair. Chronic sleep loss visibly worsens hollowing and dark circles.
- Nutrition: Iron, vitamin C, and vitamin E all support the skin and soft tissue around your eyes. If your diet is lacking in leafy greens, citrus, nuts, or lean protein, correcting that can make a noticeable difference over several weeks.
- Sun protection: UV exposure breaks down collagen faster than almost anything else. Sunscreen and sunglasses protect the thin under-eye skin from accelerated aging.
- Quit smoking: Smoking degrades both collagen and skin elasticity, directly contributing to sagging and hollowing around the eyes.
These changes won’t reverse deep, structural hollowing caused by fat loss or bone changes. But for mild cases, or as a complement to other treatments, they genuinely help.
Dermal Fillers for Moderate Hollowing
Injectable hyaluronic acid fillers are the most popular non-surgical treatment for sunken under eyes. A practitioner injects a small amount of gel-like filler directly into the tear trough to restore lost volume. The procedure typically takes 15 to 30 minutes, and results are visible immediately.
Several filler products are commonly used in this area, each lasting a different length of time. Restylane-L typically lasts 10 to 18 months. Juvederm Volbella lasts around 12 months. Restylane Eyelight lasts 9 to 15 months. Belotero Balance, a softer filler often chosen for very thin skin, lasts 6 to 12 months. Your practitioner will recommend a specific product based on how deep your hollowing is and how thin the overlying skin appears.
Cost typically runs $600 to $1,500 per syringe, and most people need one to two syringes for a complete treatment. That puts the total investment between roughly $1,000 and $2,000. Since fillers gradually dissolve, you’ll need maintenance treatments once or twice a year to keep results.
The under-eye area is one of the trickiest spots to inject, so choosing an experienced provider matters more here than almost anywhere else on the face. Bruising and swelling are common for a few days afterward. More serious complications, like filler migrating into visible lumps, are rare but do happen with less skilled injectors.
Surgical Options for Deeper Hollowing
When hollowing is severe, or when you want a longer-lasting result than fillers provide, lower blepharoplasty is the surgical option. The most common modern technique is called transconjunctival lower blepharoplasty with fat repositioning. Instead of removing the puffy fat pads that often accompany deep tear troughs, the surgeon moves that fat downward to fill the hollow. This avoids visible scars because the incision is made inside the lower eyelid.
A recent randomized study comparing a modified fat repositioning technique against traditional approaches found that the newer method maintained results better over time, with lower rates of fat resorption and tear trough recurrence. The modified technique also took less time in surgery, averaging about 41 minutes. Recovery from transconjunctival blepharoplasty is relatively quick compared to more invasive facial surgeries, with most swelling and bruising resolving within one to two weeks.
Surgery costs significantly more upfront, typically $4,000 to $7,000 for lower blepharoplasty. But because results are long-lasting (often a decade or more), it can be more cost-effective over time than repeated filler treatments. Surgery makes the most sense for people with moderate to severe hollowing, excess skin, or prominent fat pads that fillers alone can’t address.
How To Assess Your Own Severity
Not all sunken under eyes need the same approach. A simple way to gauge your situation: look in a mirror with overhead lighting, which exaggerates shadows. If the hollowing is barely visible in normal, front-facing light and mainly shows up in harsh lighting or when you’re tired, you’re dealing with a mild case. Topical products, hydration, and better sleep may be enough.
If the hollow is visible in normal lighting and creates a clear shadow or color difference between your lower lid and cheek, that’s moderate hollowing. This is the sweet spot for dermal fillers. If the hollowing extends across most of the lower lid, connects to a visible groove running toward the cheek, or comes with loose, crepey skin, you’re looking at more advanced volume loss where surgery produces the most reliable improvement.
Clinicians use formal grading systems to classify tear trough severity into distinct classes, which helps them match the right treatment to the right patient. You don’t need to know the clinical classifications yourself, but understanding that treatment should scale with severity helps you avoid both underspending on something ineffective and overspending on something unnecessary.
