Arm Lift and Thigh Lift: Options for Sagging Skin After Weight Loss

Submuscular vs Subglandular Breast Implant Placement (Dual Plane)
11 August 2026If your face looks tired even after a full night of sleep, the reason often lies in the under-eye area. The skin around the eyes is among the thinnest on the body, so even small changes in the structures underneath can become clearly visible from the outside. Under-eye filler, sometimes called tear trough filler, is one of the options that may be considered in suitable patients whose hollowing is related to volume loss.
Why the under-eye area looks tired
Under-eye shadowing rarely has a single cause. Contributing factors commonly include:
- Inherited structure: in some people the hollow is visible from a young age.
- Volume loss: support tissue in the midface can decrease over time, creating a visible transition line between the lower eyelid and the cheek.
- Thin skin: underlying vessels may give a bluish or purple impression.
- Pigmentation: darkening can be independent of volume, in which case the contribution expected from a filler may be limited.
- Daily habits: irregular sleep, smoking, high salt intake and allergic conditions can increase temporary swelling and shadowing.
Which factor dominates varies from person to person, and this distinction guides the approach that is chosen.
What is under-eye filler?
Products used in this area are usually hyaluronic acid based, with a flow behaviour and water-binding capacity selected specifically for the lower eyelid. The aim is not to fill the region but to provide enough support to soften the shadow created by the hollow. The under-eye area is prone to swelling and leaves little margin for error, so product choice, the amount used and the depth of placement all matter.
In people considered suitable after examination, the procedure is generally performed with a topical anaesthetic cream, using a needle or a cannula. The application itself is short, but the process and the outcome vary from person to person.
After the procedure
Mild swelling, tenderness and occasional bruising may be seen afterwards and usually settle within a few days. Frequently recommended points include:
- Avoiding pressure or rubbing over the area in the first days
- Not sleeping face down
- Staying away from strenuous exercise, saunas and very hot environments early on
- Avoiding a very salty diet that may increase swelling
- Not using any medication or product outside your doctor’s advice
The result may take a few weeks to settle, so the early appearance is not treated as the final outcome. A follow-up visit is advised.
Is it suitable for everyone?
Under-eye filler is not the answer to every tired appearance. When there is pronounced fat herniation, advanced skin laxity or darkening driven mainly by pigment, the contribution expected from a filler may remain limited and other approaches may be discussed instead. Pregnancy and breastfeeding, active infection in the area, certain autoimmune conditions and situations affecting bleeding tendency are all taken into account. Suitability can only be determined by a medical examination.
Frequently Asked Questions
How long does the effect last?
Duration depends on the product used, the area treated and individual metabolism. It is not a permanent application and the effect decreases over time. Giving a fixed period would not be accurate; expectations are discussed with your doctor after an examination.
Is bruising common afterwards?
The area around the eyes has fine vessels and is prone to bruising. Mild bruising and swelling may occur and usually resolve within a short time, though this varies between individuals.
Can the filler be reversed?
With hyaluronic acid based products, the use of a dissolving enzyme may be considered when the doctor deems it necessary. That decision is based on examination findings.
