Under-eye filler
Cosmo Clinic Team
Under-Eye Filler (also known as tear trough filler) is a non-surgical treatment that addresses hollowness, dark circles, and tired appearance beneath the eyes. Using volumising hyaluronic acid dermal fillers, the area is gently filled and smoothed to refresh the under-eye contour.
At Cosmo Clinic in Lisbon, tear trough filler is one of the more technically demanding filler procedures due to the delicate anatomy and thin skin of the area. Our doctors assess each patient's anatomy thoroughly before proceeding and use conservative volumes to ensure a natural result.

FAQ
What causes under-eye hollows or dark circles?
They may be due to aging, genetics, fat loss, or pigmentation. Filler corrects volume loss and reduces shadowing.
Is the treatment safe for such a delicate area?
Yes – when performed by experienced professionals using advanced techniques and suitable filler types.
How long do results last?
Typically 9 to 12 months depending on skin condition, metabolism, and filler product.
Will I look natural?
Absolutely. The goal is a refreshed, not overdone look – maintaining your natural expressions and contours.
Is under-eye filler painful?
The tear trough area is sensitive. Topical anaesthetic is applied before treatment, and a fine cannula technique is often used to minimise trauma. Most patients describe mild discomfort rather than significant pain.
Is there any downtime after tear trough filler?
Mild swelling and bruising in the periorbital area is common and can last 5–10 days. The under-eye area is prone to bruising due to the density of small blood vessels. Patients are advised to plan treatment away from important events.
How long does the treatment take?
The procedure itself takes approximately 20–30 minutes. Assessment, discussion, and consent form completion precede any treatment. At Cosmo Clinic, no treatment is performed without a prior consultation.
What is the difference between tear trough filler and under-eye filler?
The terms are used interchangeably. The tear trough is the anatomical groove between the lower eyelid and the cheek. Filler is placed in or around this groove to reduce the shadow and hollow that creates the appearance of dark circles or fatigue.
