Maintaining your under-eye filler results starts with choosing the right injector and continues with the habits you keep between appointments. From consistent sun protection and a hydration-focused skincare routine to strategically timed touch-ups, the choices you make after treatment directly influence how long your results last. Board-certified oculofacial plastic surgeon Dr. Flora Levin, MD, FACS, brings an unmatched understanding of periorbital anatomy to every under-eye filler treatment she performs at her Westport, Connecticut, practice.
In this blog, we'll discuss what affects under-eye filler longevity, how to protect your results with the right skincare habits, when to schedule maintenance treatments, which complementary procedures can extend your results, and why your injector's expertise matters.
What Affects How Long Under-Eye Filler Lasts?
Under-eye filler, most commonly hyaluronic acid (HA), generally lasts longer than filler placed in other areas of the face. Research has shown that tear trough HA fillers can maintain significant improvement for up to 18 months and, in some cases, even longer. The under-eye area experiences far less muscle movement than the lips or nasolabial folds, which allows the filler to remain stable for an extended period.
- Individual metabolism: Patients with faster metabolic rates tend to break down hyaluronic acid more quickly, which can shorten the duration of results.
- Filler type and formulation: Not all HA fillers are created equal. Products specifically formulated for the delicate periorbital area use lower HA concentrations and specialized cross-linking to minimize swelling and integrate smoothly beneath thin under-eye skin.
- Injection depth and technique: Filler placed at the appropriate depth by an experienced injector integrates more naturally with the surrounding tissue and tends to maintain its correction longer.
- Age and skin quality: Older patients with thinner skin and less natural collagen may see results fade differently than younger patients, though the under-eye area's minimal movement still works in their favor.
Dr. Flora Levin, MD, FACS, selects the filler formulation and injection approach best suited to each patient's unique anatomy, ensuring natural-looking results that last.

How Sun Protection Directly Impacts Filler Longevity
UV exposure is one of the most controllable factors that can shorten the lifespan of your under-eye filler. Sunlight generates free radicals that accelerate the breakdown of both your body's natural hyaluronic acid and the injected filler while also degrading the collagen that supports your skin's structure.
- Daily broad-spectrum SPF: Wearing sunscreen with at least SPF 30 every day, even on cloudy days, is the single most effective step you can take to preserve your filler results and overall skin health.
- Reapplication matters: Sunscreen should be reapplied every two hours during extended outdoor exposure, especially around the delicate eye area, where skin is thinnest.
- Physical barriers: Sunglasses with UV protection and wide-brimmed hats provide an additional layer of defense for the under-eye area specifically.
- Avoid tanning: Tanning beds and prolonged sun exposure without protection accelerate photoaging and can undo the rejuvenating effects of your filler treatment.
Skincare Habits That Support Your Results
What you apply to your skin every day can complement your under-eye filler and help the treated area look refreshed for longer. A targeted skincare routine supports the skin's natural hydration and collagen production, creating a healthier foundation for the filler to sit within.
- Hyaluronic acid serums: Topical HA draws moisture into the skin, which supports the hydrating properties of the filler beneath the surface and helps maintain a plump, smooth appearance.
- Retinoids: Prescription or over-the-counter retinoids stimulate collagen synthesis and improve skin texture, though patients should wait until any post-treatment sensitivity has fully resolved before reintroducing them.
- Vitamin C: A daily antioxidant like vitamin C helps neutralize free radicals caused by UV exposure and environmental stressors, protecting both your skin and your filler from premature breakdown.
- Gentle eye care: The under-eye area is exceptionally delicate. Avoid tugging or rubbing at the skin when applying products, removing makeup, or cleansing; friction can displace filler and contribute to skin laxity over time.
When to Schedule Maintenance Treatments
One of the most effective strategies for long-term under-eye filler maintenance is scheduling touch-up appointments before your results have fully faded. Waiting until the filler has completely dissolved means starting over from baseline, which often requires more product and more correction.
- The 75% rule: Many experienced injectors recommend scheduling a touch-up when approximately 75 to 80% of the filler's effect is still visible, rather than waiting for complete dissolution.
- Typical maintenance timeline: For most patients, under-eye filler touch-ups occur 12 to 18 months after the initial treatment, though individual timelines vary based on metabolism and lifestyle factors.
- Fewer products over time: Maintenance sessions typically require less filler than the initial treatment, since the goal is to restore a small amount of lost volume rather than rebuild correction from scratch.
Dr. Levin carefully tracks each patient's treatment history and response, helping determine the ideal maintenance schedule for lasting, natural-looking results.
Why Your Injector's Expertise Matters Most
Choosing the right injector determines how well your results hold up and how safely they can be maintained over time.
- Product selection: Not every filler is appropriate for the under-eye area. An experienced specialist selects products with the right viscosity, HA concentration, and cross-linking for the thin, delicate tissue around the eyes.
- Complication management: Should any issue arise, asymmetry, swelling, or migration, an oculofacial plastic surgeon like Dr. Levin has the training and tools to address it promptly, including the ability to dissolve HA filler with hyaluronidase if needed.
- Long-term planning: Dr. Levin approaches under-eye filler as part of a comprehensive, long-term rejuvenation plan rather than a one-time fix, ensuring results evolve gracefully with your face over the years.
