Differences Between Under-Eye Light Filler and Fat Grafting

Dark circles, hollow under eyes, and that “tired look” are among the most common concerns patients bring to plastic surgeons. In Ontario, more and more people are turning to fat injections under eyes or dermal fillers to restore a youthful, refreshed appearance.

While both treatments aim to smooth hollows and improve under-eye contour, there are big differences in how they work, how long results last, and what patients can expect.

At Grand Genesis Plastic Surgery (GGPS), we specialize in both techniques. In this article, we’ll break down the differences between under-eye light fillers and fat grafting—so you can decide which might be right for you.

What Is Under Eye Fat Transfer?

Under eye fat transfer (also called fat injections under eyes, fat graft under eyes, or fat transplant under eyes) is a cosmetic procedure that uses your own fat to restore lost volume around the eyes.

Instead of relying on synthetic fillers, this approach takes fat from another part of your body—like the thighs, abdomen, or hips—and carefully injects it into the delicate under-eye region.

Because it uses your own tissue, many patients consider it a more natural and longer-lasting option compared to dermal fillers.

How the Procedure Works

The process of under eye fat grafting involves three main steps:

Harvesting the Fat

The surgeon begins by performing a gentle liposuction on a donor area, usually the abdomen or thighs. This is a small, minimally invasive step, but it provides the “raw material” for the fat graft.

Processing and Purification

The harvested fat isn’t injected right away. It undergoes a careful purification process to remove excess fluid, oils, and damaged cells. This ensures that only the healthiest, most viable fat cells are used.

Injection into the Under Eye Area

Once purified, the surgeon uses a fine cannula to inject the fat under the eyes. The goal is to fill hollows, smooth out shadows, and improve the contour between the lower eyelid and the cheek.

Because this is a delicate area, precision and artistry are crucial. At GGPS, our team specializes in facial fat grafting under eyes for natural, balanced results.

Benefits of Fat Injections Under Eyes

Why do patients choose fat filler for under eyes instead of synthetic fillers?

• Natural look and feel – Since it’s your own tissue, results look soft and natural.
• Longer-lasting – Unlike hyaluronic acid fillers, fat can integrate with surrounding tissue and last for years. (Learn more in our guide: How Long Does Fat Grafting Last?)
• Dual benefit – You also get minor contouring from the area where fat was harvested.
• Biocompatible – No risk of allergic reaction since the material comes from your own body.

Potential Risks and Side Effects

Like any cosmetic procedure, under eye fat grafting carries some risks. The most common include:

• Temporary swelling and bruising
• Mild discomfort at both the donor and injection sites
• Unevenness or overcorrection if fat doesn’t “take” evenly
• Rare risks like infection or cyst formation

Choosing an experienced surgeon minimizes these risks and helps ensure smooth, natural results.

Recovery Process and Timeline

Immediate Aftercare

After the procedure, patients can expect some swelling and bruising. Cold compresses and following your surgeon’s aftercare instructions are key.

Recovery Time and Swelling

Most people feel comfortable returning to work within 7–10 days. However, swelling may take a few weeks to fully resolve.

Long-Term Results

Fat grafting can last for years, though not all transferred fat survives. Surgeons often slightly overfill the area to account for natural reabsorption. For many patients, results are semi-permanent—unlike fillers that require touch-ups every 6–12 months.

Fat Injections vs. Dermal Fillers Under Eyes

So how do fat injections around eyes compare with traditional dermal fillers like hyaluronic acid?

• Longevity – Fat transfer can last several years, while fillers typically last 6–12 months.
• Natural tissue – Fat uses your own cells, fillers are synthetic.
• Procedure complexity – Fat transfer involves liposuction and processing, while fillers are quicker and done in-office.
• Recovery – Fillers have almost no downtime, while fat grafting may require 1–2 weeks of healing.
• Cost – Fat transfer may cost more upfront but often saves money over time since it lasts longer.

Both options have their place. Some patients start with fillers to “test the look,” then move to fat grafting once they’re ready for a more permanent solution.

Who Is a Good Candidate?

You may be a good candidate for under eye fat grafting if you:

• Have hollowing, shadows, or fat loss under the eyes
• Are in good overall health
• Have enough donor fat in another area
• Want longer-lasting results than fillers can provide

Patients with severe skin laxity or certain medical conditions may be better suited for other procedures. During consultation, your surgeon will evaluate your unique needs.

Cost of Under Eye Fat Transfer

The cost of under eye fat injections in Ontario varies depending on the surgeon’s expertise, the extent of treatment, and whether additional procedures are combined (such as a breast lift and fat transfer or facial rejuvenation).

While it may be more expensive than dermal fillers, many patients view it as an investment in long-lasting, natural results.

Reviews and Patient Experiences

Patients often describe under eye fat grafting as transformative. Many say they look less tired, more youthful, and feel more confident without makeup.

Some share that it took a little patience during the healing process, but they’re thrilled with the outcome. You can find more about fat transfer in our blog: Can Implants Be Replaced with Fat Transfer?
