Under-eye hollows are often caused by age-related volume loss beneath the eyes. Fat grafting, also known as micro-fat or nanofat grafting, uses the patient's own purified fat to naturally restore lost volume and rejuvenate the under-eye area. This technique can also help camouflage mild under-eye bags by restoring volume around the lower eyelid, creating a smoother and more youthful transition between the eyelid and the cheek.
About the Procedure
General Information
Treatment for under-eye hollows and eye bags may involve different surgical or non-surgical techniques. Depending on the patient’s anatomy and aesthetic goals, treatment may include:
- Fat grafting (Micro-fat/Nanofat)
- Hyaluronic acid fillers
- Lower eyelid surgery (Blepharoplasty), with or without fat grafting
The most appropriate approach is determined after a comprehensive consultation and detailed facial assessment.
What is Radiesse?
Fat grafting may be recommended for patients with:
- Hollow under-eye circles caused by volume loss
- Tear trough deformities
- Mild under-eye bags accentuated by surrounding volume deficiency
- Purple under-eye circles resulting from thin skin and lack of soft tissue coverage
- Age-related facial volume loss around the eyes
By restoring natural volume beneath the eyes, fat grafting softens the transition between the lower eyelid and the cheek while improving the overall appearance of the eye area.
Consultation & Preoperative Assessment
A thorough examination of the lower eyelids is performed to determine the underlying cause of under-eye hollows and eye bags.
The choice between fat grafting and hyaluronic acid filler depends on several factors, including facial anatomy, treatment goals, and patient preference.
Unlike fillers, fat grafting is performed in the operating room under light general anesthesia or intravenous sedation and provides long-lasting results. It is often combined with facial rejuvenation procedures such as facelift surgery or lower eyelid blepharoplasty.
Before surgery, patients will:
- Meet with the anesthesiologist
- Undergo routine blood tests, including coagulation studies
- Be advised to stop smoking for at least one month before surgery to improve fat survival and healing
- Discontinue aspirin and anti-inflammatory medications for 10 days before the procedure, unless otherwise directed by their physician
Recovery & Aftercare
Most patients can return to their normal daily activities immediately after treatment.
For optimal results, it is recommended to:
- Avoid direct sun exposure and excessive heat for the first 24 hours
- Avoid strenuous exercise for 24 hours
- Avoid excessive massage of the treated area unless instructed by your physician
- Apply cold compresses if mild swelling or redness occurs
Procedure
Fat grafting to the lower eyelids is performed under light general anesthesia or intravenous sedation.
The procedure typically takes approximately one hour.
Fat is gently harvested from another area of the patient’s body, carefully purified, and processed into extremely fine particles (micro-fat or nanofat) suitable for the delicate skin of the lower eyelids.
The purified fat is then precisely injected using fine cannulas to restore volume and achieve a smooth, natural contour.
Recovery & Aftercare
Patients usually return home on the same day.
Since fat harvesting is minimally invasive, discomfort is generally mild and can be managed with simple pain medication for a few days.
Recovery may include:
- Mild swelling
- Bruising around the eyelids, which is common due to the delicate tissues
- Bruising usually resolves within 8–10 days and may be concealed with makeup once appropriate
Most patients can resume light daily activities the following day, while more strenuous activities should be postponed according to their surgeon’s recommendations.
Possible Complications
Fat grafting is considered a safe procedure when performed by an experienced surgeon.
Potential but uncommon complications include:
- Mild swelling
- Bruising
- Temporary asymmetry
- Small palpable or visible fat nodules if fat is placed too superficially
The use of highly refined micro-fat or nanofat and specialized microcannulas significantly reduces these risks.
Results & Longevity
Fat grafting provides long-lasting and often permanent improvement because the transferred fat becomes integrated into the surrounding tissues.
However, significant weight fluctuations may affect the final result:
- Weight loss may reduce the restored volume beneath the eyes.
- Weight gain may increase the fullness of existing under-eye bags.
Once healing is complete, patients enjoy a smoother, brighter, and more youthful under-eye appearance with natural-looking results.
