Under-Eye Surgery or Dermal Filler?

For under-eye bagginess and hollowing, both surgery (lower blepharoplasty or fat transfer) and dermal filler can be an option. Surgery tends to suit noticeable excess skin or fat, filler tends to suit mild volume loss; the exact choice is confirmed at examination, since it depends on the complaint's source and severity.

Lower blepharoplasty surgically removes or repositions excess skin and fat in the lower lid, while fat transfer restores lost volume with the patient's own fat tissue; both aim for a permanent change and are day-case procedures under local anaesthesia. Fat transfer moves fat from another part of the body to the under-eye area. When excess tissue and volume loss occur together, the two procedures can be planned in the same session.

Dermal filler is an injection-based treatment that temporarily fills mild under-eye hollowing without surgery, usually with hyaluronic acid-based products, in a short session of a few minutes. Its effect is not permanent — the body gradually absorbs it, and it needs repeating at certain intervals. Because the skin here is thin and mobile, filler requires experience: the wrong amount or layer can cause a bluish shadow or an irregular contour. Filler does not remove excess tissue, it only fills a volume deficit, so in a patient with excess skin or fat it can make the bagginess look more pronounced rather than less.

The main difference is permanence and invasiveness: surgery achieves a lasting correction and needs recovery time, while filler is temporary, less invasive, and fades over time. Surgery directly addresses excess skin or fat pushed forward, whereas filler only compensates for a tissue deficit with an added substance — it does not reduce excess skin or fat. Using only filler on a patient with noticeable excess tissue may therefore not deliver the expected relief. Surgery needs planned preparation in an operating theatre; filler needs only a short session in the examination room.

For patients who want to weigh the two options side by side, the main differences are summarised in the table below; which one suits you is determined not by this table but by the findings at examination.

Lower blepharoplasty or fat transfer tends to suit patients with noticeable excess skin, herniated fat, or those wanting a permanent solution. In patients whose bagginess has grown more pronounced over the years, whose skin has lost elasticity, and who do not expect a satisfying result from temporary methods like filler, surgery is generally discussed first. Patients who tried filler before without satisfaction also tend to ask about surgery in more detail.

Dermal filler can suit patients with mild volume loss who are not yet ready for surgery, want a temporary solution, or wish to try a first step before deciding on surgery — since its effect fades, it must be repeated at intervals. In younger patients without noticeable excess skin or fat, who describe only mild under-eye hollowing, filler can be a less invasive first step compared with surgery.

Op. Dr. Anıl Kaya (eye surgeon, ophthalmologist) weighs whether the under-eye issue stems from excess skin/fat or from volume loss, the severity of the problem, the patient's age, and whether a permanent or temporary solution is wanted. Using only filler when there is noticeable fat herniation or excess skin may not deliver the expected relief, since it does not resolve the structural problem; such cases usually call for surgery. For mild, limited volume loss, if the patient is not yet ready for surgery, filler can be a temporary interim option. Age also matters: filler suits younger patients with mild volume loss better than older patients whose skin elasticity has also decreased. The examination also asks about any earlier filler or injection and satisfaction with it, to help manage expectations.

To clarify which option suits you, see the assessment on the 'Which Eyelid Surgery Is Right for Me?' page, then confirm the final decision with your doctor at examination. A simple check clarifies whether your under-eye complaint involves excess skin or fat, or volume loss, and also indicates which technique - through the skin or the inner lid surface - would suit better if surgery is chosen. For undecided patients, a direct tissue assessment at examination is more reliable than guessing.

You can book an appointment with Op. Dr. Anıl Kaya to find out whether surgery or filler suits your under-eye concern. At examination, the source and severity of your complaint, together with your expectations, are assessed to clarify the most suitable approach.
