Under-eye hollows — also called tear troughs — are one of the most common reasons patients seek dermal filler treatment. Dark circles and sunken under-eye bags can make you look perpetually tired, even when you are well-rested. Tear trough filler places a small amount of hyaluronic acid filler beneath the lower eyelid to smooth the transition between the eyelid and the cheek, producing a refreshed, brighter-eyed appearance that concealer alone cannot achieve.

What Causes Under-Eye Hollows and Dark Circles

The under-eye area is naturally thin-skinned and prone to volume loss. As the fat pads beneath the eyes diminish with age, a shadow forms in the tear trough that creates the appearance of dark circles and under-eye bags. Loss of mid-face volume accelerates this effect — when the cheeks deflate, the under-eye hollow becomes more pronounced. This is why under-eye filler and cheek augmentation are often performed together for optimal results.

Expert Tear Trough Filler Technique

The under-eye area is one of the most delicate regions to inject, requiring advanced technique and thorough anatomical knowledge. Sarah uses a conservative approach to dark circles treatment, placing small amounts of hyaluronic acid filler precisely where needed and building gradually. Key aspects of her technique include:

• Cannula use — A blunt-tipped cannula reduces bruising and provides smoother, more even filler placement
• Layered approach — Small amounts of filler are placed in precise layers to avoid overcorrection
• Structural assessment — Evaluating whether cheek filler may address the under-eye concern from above
• Conservative philosophy — Less is more in this delicate area, with the option to add volume at a follow-up

Under-Eye Filler Results and Recovery

Under-eye filler appointments take about 20-30 minutes. You will see improvement immediately, though minor swelling may be present for a few days. Full results are typically visible within one to two weeks. Tear trough filler generally lasts 9-12 months, and because the under-eye area has less movement than areas like the lips or jawline, results can sometimes last even longer.

This treatment is part of our comprehensive injectable services and pairs well with nasolabial fold filler and chin filler for full-face rejuvenation. Under-eye filler is best suited for patients with volume loss rather than excess skin or puffiness.
