Frequently Asked Questions: Under-Eye Bags

​

Q: What causes under-eye bags, and why does under-eye puffiness appear after waking up?

A: Permanent under-eye bags are usually caused by fat beneath the eyes shifting or sagging with age. Temporary puffiness after waking up, on the other hand, is usually caused by fluid retention during sleep — especially after staying up late, sleeping flat, or eating salty food before bed. Allergies and crying before sleep are also common causes. If the puffiness comes with redness or pain, you should see a doctor to check for an underlying cause (such as inflammation or infection).

​

Q: How is under-eye fat repositioning different from traditional under-eye bag surgery that removes the fat, and what does it help with?

A: Fat repositioning redistributes the existing under-eye fat to smooth out hollows or shadows while preserving the natural structure — suitable for cases where the main issue is an "under-eye groove/hollow" rather than bulging fat. Traditional under-eye bag surgery, by contrast, removes/trims the excess fat and is suitable for cases with clearly visible bulging under-eye bags. A doctor will assess which approach is right for you.

​

Q: Does under-eye bag surgery/fat repositioning hurt, and is it dangerous?

A: The procedure is performed under local anesthesia (in some cases combined with light sedation or general anesthesia). During the procedure you will only feel tightness or pressure, not clear pain. Afterward there may be mild tightness or a burning sensation for the first 2-3 days. Risks such as swelling, bruising, or asymmetrical results are greatly reduced when performed by a doctor experienced specifically in periocular (around-the-eye) surgery.

​

Q: How many days of recovery are needed, and how much does it cost?

A: The main recovery period is about 7-14 days, with swelling and bruising gradually subsiding. Heavy exercise and strenuous work should be avoided during this time. Under-eye fat repositioning costs approximately 35,000-80,000 baht, depending on the technique and whether it is combined with lower eyelid skin removal. It's best to consult a doctor for a price assessment based on your actual case.

​

Q: How long do the results last, and will the fat/under-eye bags come back?

A: Results from under-eye bag surgery/fat repositioning generally last many years — typically 5-10 years or more — because it restructures the tissue rather than being a filler injection that dissolves quickly. Even though the removed fat will not return exactly as before, natural age-related sagging can still occur, so the under-eye hollow may become more visible again as you get older.

​

Q: Can under-eye filler fix deep hollows? How long does it last, and how can it cause lumps?

A: Filler injections for under-eye hollows give temporary results, lasting about 9-18 months; once the filler dissolves, the hollow may become visible again. Lumps from filler are usually caused by substandard filler products, or by massaging, pinching, or touching the face after injection, causing the filler to shift out of place. To prevent this, avoid touching the injected area in the early period and choose an experienced doctor for the injection.

​

Q: Can deep-set eyes/deep under-eye hollows be surgically corrected? Can this be done together with under-eye bag surgery?

A: Deep-set eyes can be corrected with several methods, such as surgery to advance the eyelid-opening muscle or injecting the patient's own fat onto the eyelid — these are different procedures from double eyelid surgery, and can be performed at the same time as under-eye bag surgery since they address different areas. Results are not guaranteed to be permanent in every case, depending on the underlying cause, age, and aftercare.
