Under-eye hollows are caused by volume loss beneath the skin, and getting rid of them depends on how deep the hollowing is. Mild cases can be improved with topical skincare and lifestyle changes, while moderate to severe hollows typically require professional treatments like fillers or surgery to restore lost volume. Understanding what’s actually happening beneath your skin helps you choose the right approach.
Why Under-Eye Hollows Develop
The area beneath your eyes is one of the thinnest skin regions on your body, which makes any structural change underneath immediately visible. Several factors work together to create that sunken look. The fat pads that sit over your cheekbones shrink and slide downward with age, making the transition between your lower eyelid and cheek more dramatic. Bone resorption around the eye socket also plays a role: the rim of bone beneath your eye gradually recedes over time, removing the scaffolding that once supported the overlying skin and tissue.
Some people develop under-eye hollows in their twenties or even earlier. The tear trough, that indentation running from the inner corner of your eye outward, can be visible at a young age simply because of how the muscles and ligaments attach to the bone in that area. Genetics largely determine how prominent this groove is. If your parents had deep-set eyes or thin under-eye skin, you’re more likely to deal with hollowing earlier in life. Dehydration, weight loss, and poor sleep can all make existing hollows look worse by further thinning the skin or darkening the area through visible blood vessels.
What Topical Products Can (and Can’t) Do
Skincare products won’t fill in a deep structural hollow, but they can meaningfully improve mild hollowing and prevent the area from looking worse over time. The key is choosing ingredients that thicken the skin and boost hydration in a region where both are naturally limited.
Hyaluronic acid serums draw moisture into the skin and temporarily plump fine lines, making the under-eye area look smoother and less hollow. This effect is cosmetic and lasts only while you’re consistently using the product. Peptides, particularly palmitoyl pentapeptide-4, stimulate your skin to produce more collagen and elastin, the structural proteins responsible for firmness. Over weeks to months of regular use, peptides can improve skin thickness and elasticity in the under-eye area. Retinol works similarly by accelerating cell turnover and boosting collagen, though you’ll want to start with a low concentration since the under-eye skin is easily irritated.
Caffeine-based eye creams are popular but serve a different purpose. Caffeine constricts blood vessels, which reduces puffiness and the dark appearance caused by visible vasculature. It won’t restore volume, but it can make hollow areas less shadowed and therefore less noticeable.
Why Home Remedies Have Limits
Cold compresses, chilled spoons, and cucumber slices all work through the same basic mechanism: constricting blood vessels beneath thin skin. This can reduce puffiness and temporarily minimize dark circles, but it does nothing to address the volume loss that creates a true hollow. If your under-eye concern is primarily puffiness or discoloration, cold compresses applied for up to 20 minutes can help. Never apply ice directly to the skin, and avoid chemical cooling packs near your eyes since leaking chemicals can cause damage.
Adequate sleep, staying hydrated, and reducing salt intake all minimize fluid retention and keep the under-eye area looking its best. These habits matter, but they’re maintenance strategies, not solutions for structural hollowing. If your hollow is visible even when you’re well-rested and hydrated, the cause is anatomical, and topical or lifestyle changes alone won’t resolve it.
Hyaluronic Acid Fillers
Injectable hyaluronic acid filler is the most common professional treatment for under-eye hollows. A practitioner injects small amounts of gel-like filler into the tear trough to replace lost volume and smooth the transition between the lower eyelid and cheek. The procedure typically takes 15 to 30 minutes, and results are visible immediately.
The reported duration of results ranges from 8 to 12 months on average, but recent research suggests the effects last longer than previously thought. A retrospective study published in The Journal of Clinical and Aesthetic Dermatology found significant results persisting up to 18 months, with some patients showing visible improvement even at the 24-month mark. Objective 3D imaging measurements showed an average volume augmentation lasting 14.4 months, while patients themselves reported noticing the effect for an average of about 11 months. Cost typically falls between $600 and $1,200 per session depending on geographic location and the amount of filler used.
The under-eye area carries specific risks that other filler sites don’t. The Tyndall effect, a bluish discoloration visible through the skin, occurs when filler is placed too superficially. The tear trough is one of the most common sites for this complication because the skin there is so thin. The discoloration can appear immediately or develop over the following days, and without correction, it can persist for months or years. The area may also look slightly raised or lumpy. Vascular occlusion, where filler inadvertently blocks a blood vessel, is a rarer but more serious risk. Choosing an experienced injector who specializes in the under-eye area significantly reduces the likelihood of both complications. One advantage of hyaluronic acid fillers: they can be dissolved with an enzyme if the results are unsatisfactory or complications arise.
Platelet-Rich Fibrin (PRF) Injections
PRF is a regenerative treatment that uses your own blood to stimulate collagen production and tissue thickening in the under-eye area. A small blood sample is drawn, processed to concentrate growth factors, and injected beneath the eyes. Because the material comes from your own body, there’s no risk of allergic reaction or the Tyndall effect.
Results from PRF are more gradual and subtle than fillers. Most people need two to three sessions spaced four to six weeks apart before seeing noticeable improvement. The treatment works best for mild to moderate hollowing where the goal is to improve skin quality and add modest volume rather than fill a deep groove. PRF won’t produce the immediate, dramatic correction that fillers can, but some people prefer the more natural, progressive improvement.
Surgical Options for Severe Hollowing
When hollowing is deep enough that fillers alone can’t correct it, or when you want a longer-lasting solution, surgery becomes relevant. The most effective procedure is lower blepharoplasty with fat repositioning. Rather than removing the puffy fat pads that often accompany hollowing (which can actually worsen the sunken appearance), the surgeon releases the fat from its original position and drapes it over the orbital rim into the hollow. This simultaneously reduces puffiness above and fills the depression below, creating a smoother contour.
Fat grafting is another surgical approach where fat is harvested from elsewhere on your body (often the abdomen or thighs), processed, and injected beneath the eyes. This provides more volume than repositioning alone and can be effective for people who don’t have excess under-eye fat to redirect. Results from fat grafting are long-lasting, often permanent, though some of the transferred fat is naturally reabsorbed by the body in the first few months, meaning your surgeon will typically slightly overfill the area.
Recovery from lower blepharoplasty involves about one to two weeks of noticeable bruising and swelling, with most people returning to work within 10 to 14 days. Final results settle over two to three months as swelling fully resolves. The procedure carries standard surgical risks including infection, scarring, and in rare cases, changes to eyelid position.
Choosing the Right Approach
The best treatment depends on the severity of your hollowing and what you’re willing to invest in time, money, and recovery. Mild hollowing with thin, dehydrated-looking skin often responds well to a consistent topical regimen built around peptides, hyaluronic acid, and retinol. You can expect gradual improvement over two to three months.
Moderate hollowing, where shadows are visible even in good lighting, is where fillers and PRF become worthwhile. Fillers offer immediate results with minimal downtime, while PRF provides a more subtle, gradual improvement with fewer risks. For deep, structural hollowing that’s been present for years or is worsening significantly, surgical correction provides the most complete and long-lasting result.
Many people combine approaches. Using peptide-based eye creams to maintain skin thickness while getting filler touch-ups every 12 to 18 months is a common strategy that addresses both the skin surface and the volume loss beneath it. Starting with the least invasive option and escalating only if needed is a reasonable path for most people.
