Tear trough hollows—those sunken lines running from the inner eye to the mid-cheek—are a common cosmetic concern that can make you look tired or older than you feel. This guide explores what causes tear trough hollows, the range of medical procedures available to treat them, and why South Korea is a top destination for these treatments. Tear trough deformities are complex and often require personalized solutions. Minimally invasive options like Under Eye Thread Lifts and Under Eye Fillers can deliver quick improvements with little downtime. Meanwhile, Stem Cell Fat Grafting and PRP Fat Grafting offer natural, longer-lasting results but come with unique considerations, especially in the delicate under-eye area. South Korea stands out for its advanced techniques, skilled practitioners, and competitive pricing, making it a popular choice for medical tourists. When patients are carefully selected and procedures are performed with precision, satisfaction rates are high—helping people look and feel more refreshed.
Understanding Tear Trough Hollows: Causes and Common Terminology
Definition and Anatomical Basis
The tear trough is a naturally occurring hollow between the lower eyelid and the cheekbone, starting at the inner corner of the eye and extending outward. This area is especially prone to looking sunken because the skin is thin and lacks much subcutaneous fat, unlike the fuller upper cheek. Several key structures make up this region, including the skin, orbicularis oculi muscle, various ligaments, fat pads, and the underlying maxillary bone. Knowing this anatomy helps patients understand why tear trough hollows form and how different treatments work to correct them.
Why Tear Troughs Form
Tear trough deformity usually results from a mix of genetics and changes that come with age. Common causes include fat atrophy (loss of fat volume), weakening of supportive ligaments, and resorption of the maxillary bone. When the tear trough ligament weakens, fat pads can shift downward, making the hollow more noticeable. A naturally prominent maxillary bone can also make the area look more sunken. Other factors—like smoking, sun exposure, certain medications, hormonal changes, poor nutrition, dehydration, lack of sleep, rapid weight loss, allergies, and sinus infections—can all contribute. Rarely, tear troughs may signal underlying medical issues such as Horner's disease or thyroid problems.
Because so many factors can cause tear trough hollows, there’s no one-size-fits-all solution. For example, someone with dehydration might improve with better hydration, while another with fat loss may need volume restoration. That’s why a thorough, individualized consultation with a qualified professional is essential to get the best and safest results.
Common Pseudonyms and Associated Symptoms
People often describe tear trough deformity as "under-eye hollows" or "sunken eyes." Other terms include "dark under-eye circles," "shadows under lower lids," and "deep-set eye sockets." Symptoms can include dark circles, puffiness, fine lines, and a persistent "tired" or "aged" look—even in young or well-rested individuals. While most cases are cosmetic, true "enophthalmos" (sunken eyes due to medical conditions) requires medical attention.
The main reason people seek treatment is to look less tired or aged, which can have a big impact on self-esteem. Successful treatment should address both the physical and psychological aspects of the condition.

Medical Procedures for Under-Eye Rejuvenation
Under Eye Thread Lift: How It Works and What to Expect
An under-eye thread lift is a minimally invasive procedure that lifts and tightens the skin under the eyes, reducing wrinkles and sagging. The threads used are usually made of polydioxanone (PDO) or polycaprolactone (PCL), both of which are safely absorbed by the body over time.
PDO threads work in two ways: they provide an immediate lift and stimulate collagen production as they dissolve. Some threads have tiny barbs or cones to anchor the tissue, while others are smooth or screw-shaped for different effects. The procedure takes about 30–60 minutes under local anesthesia, with minimal bruising or swelling that usually resolves in a day or two. Results last 12–18 months, and the collagen boost can last even longer.
The immediate lift and gradual collagen regeneration make thread lifts appealing for those who want both quick and lasting improvements. Patient education is key so expectations are realistic—initial results are visible right away, but full benefits develop over several months.
Stem Cell Fat Grafting (Including Nano Fat Transfer): How It Works and What to Expect
Stem cell fat grafting uses your own fat, harvested from areas like the abdomen or thighs, to restore volume in the face. Nano fat transfer is a specialized version where the fat is processed into a fine solution for precise injection under the eyes.
The main goal is to restore lost volume, but the adipose-derived stem cells (ADSCs) in the fat also help regenerate tissue. The success of the procedure depends on how well the transplanted fat survives, which can vary widely (30–95% retention). While results can last months to years, the thin skin under the eyes makes fat grafting unpredictable—risks include lumps, chronic swelling, and uneven results. Recovery can take several weeks.
While using your own tissue reduces allergy risk and can offer long-lasting results, the unpredictability of fat survival in the under-eye area means patients should be fully informed about possible complications.
Under Eye Filler: How It Works and What to Expect
Under-eye fillers are gel-like substances injected to restore lost volume and smooth out hollows. The most popular type is hyaluronic acid (HA), which is naturally found in the skin and can be dissolved if needed. Other options include calcium hydroxylapatite (CaHA), poly-L-lactic acid (PLLA), polymethylmethacrylate (PMMA), and autologous fat injections.
Fillers provide immediate results with minimal downtime. HA fillers are especially popular for the under-eye area because they’re soft, flexible, and reversible. However, the area is delicate, and complications like swelling, bruising, irregular contours, or the bluish Tyndall effect can occur. Rarely, more serious issues like vision loss have been reported.
The ability to dissolve HA fillers with hyaluronidase is a major safety advantage, making them a preferred choice for first-time patients or those concerned about complications.
PRP Fat Grafting: How It Works and What to Expect
PRP Fat Grafting combines traditional fat grafting with platelet-rich plasma (PRP) from your own blood. The PRP is mixed with the harvested fat to enhance tissue regeneration and fat survival.
The process involves liposuction to collect fat, processing to purify it, and drawing blood to extract PRP. The PRP-enriched fat is then injected under the eyes. Theoretically, PRP improves fat survival and skin quality, but it adds cost and shares the same risks as regular fat grafting—unpredictable results, lumps, and swelling. Some studies suggest that biofillers may be more effective and have fewer side effects than PRP for under-eye hollows.

Patient Outcomes and Addressing Issues
People seek treatment for tear trough hollows mainly to look less tired or aged. The right procedure can restore volume, lift skin, and improve overall appearance.
Under Eye Thread Lift Outcomes
Patients often report high satisfaction, with immediate lifting and tightening that continues to improve as collagen builds. Minimal downtime and long-lasting results (up to three years for collagen effects) make this a popular choice.
Stem Cell Fat Grafting Outcomes
Fat grafting can provide natural, long-lasting results, with many patients satisfied. However, the under-eye area is tricky—risks include uneven results, lumps, and swelling. Some patients need revision surgery if complications arise.
Under Eye Filler Outcomes
Hyaluronic Acid fillers are popular for their quick results and reversibility. Most patients are happy with the outcome, but the area is delicate, and complications like swelling, bruising, or irregularities can occur. Rarely, serious complications happen, so precise technique is essential.
PRP Fat Grafting Outcomes
PRP Fat Grafting aims to improve both volume and skin quality. While it may enhance fat survival, it shares the same risks as regular fat grafting. Some studies suggest biofillers may be more effective and have fewer side effects than PRP for under-eye hollows.
Conclusions
Tear trough hollows are a complex issue with many causes, so treatment must be personalized. Under Eye Thread Lifts and Under Eye Fillers offer quick, effective, and often reversible results, while Stem Cell Fat Grafting and PRP Fat Grafting provide natural but less predictable outcomes. South Korea is a leading destination for these procedures, offering advanced care at competitive prices.
