Quick answer: Under eye filler before and after results depend on the depth of your tear trough, filler volume used, and injection technique. Most patients see smoother, brighter under-eye contours with significantly reduced shadows and hollow appearance. Results last 12 to 18 months, with a 91% pooled patient satisfaction rate across clinical trials.
What is under eye filler before and after? Under eye filler before and after refers to the visual change in the tear trough area following hyaluronic acid filler injections. It describes the shift from hollow, shadowed under-eye contours to a smoother, more rested appearance. The before state is typically characterized by a pronounced groove between the lower eyelid and cheek. The after state shows restored volume, reduced dark shadows, and a more continuous lower facial contour.
This guide draws on published clinical trial data, peer-reviewed meta-analyses, and retrospective studies examining hyaluronic acid filler outcomes in the periorbital region across hundreds of patients.
Why do under eyes become hollow?
The tear trough is the crescent-shaped groove that runs from the inner corner of the eye toward the outer cheek. In youth, this area is smooth and the transition from lower eyelid to cheek is continuous. With age, fat pads shift, the orbicularis oculi muscle thins, and bone remodeling in the orbital rim creates a progressive hollow.
This process often starts earlier than patients expect. Genetics, sun exposure, low body weight, and sleep deprivation all accelerate tear trough formation. The hollow creates a shadow that reads as a dark circle, making the face appear older and more fatigued than it is.
Under eye filler corrects this by restoring the lost volume in the tear trough. The result is a smoother lower eyelid-cheek junction and a reduction in the shadow that creates the appearance of dark circles.
What does under eye filler before and after look like?
The transformation from under eye filler is subtle and natural when performed correctly. A well-treated result should make you look rested and alert, not filled or puffy.
Before treatment:
- Visible groove from the inner corner of the eye toward the cheek
- Dark shadow in the hollow, not true skin pigment in most cases
- Sunken appearance under the eye, especially in certain lighting
- Pronounced transition between the lower eyelid and cheek
After treatment:
- Smoother lower eyelid-cheek contour
- Reduced dark shadow as volume fills the hollow
- More open, rested appearance
- Natural-looking results that do not look obviously injected
The key to a good result is under-correction, not over-correction. The goal is not to eliminate the tear trough entirely but to soften it so the shadow disappears and the contour blends naturally.
A 2023 systematic review and meta-analysis published in Aesthetic Plastic Surgery, which analysed 31 studies and 2,556 patients, found a pooled overall patient satisfaction rate of 91% with hyaluronic acid filler in the tear trough. This makes it one of the highest-rated non-surgical facial procedures by patient satisfaction.
Results by tear trough severity
Tear trough deformity is graded on the Hirmand classification scale from Grade 1 (mild) to Grade 3 (severe). Where you fall on this scale determines the volume needed and the realism of your outcome expectations.
Grade 1 (mild): A slight groove visible mainly in certain lighting. Results from 0.3ml to 0.5ml per side are dramatic. Shadow disappears almost entirely. Most patients in this category achieve full correction in a single session.
Grade 2 (moderate): A visible hollow with shadow visible in most lighting. Results from 0.5ml to 1ml per side are significant. The groove softens considerably and shadow reduces by 60 to 80%. A second session may be recommended to achieve optimal correction.
Grade 3 (severe): A deep, prominent hollow that extends into the cheek. Volume loss is substantial. Filler alone may not fully correct Grade 3 deformity. Results are meaningful but complete correction may require a combined approach with cheek filler or fat transfer.
A retrospective study of 155 patients published in the Journal of Clinical and Aesthetic Dermatology (JCAD) found that 68% of patients improved by one Hirmand grade following treatment, and 14% improved by two grades. The average filler volume was 0.45ml per side.
The Makeover Under Eye Outcome Assessment Framework
Choosing whether under eye filler is right for you requires evaluating four key factors before your first consultation. This framework helps set realistic expectations and identifies patients most likely to achieve their desired result.
| Assessment Factor | What to Evaluate | What It Tells You |
|---|---|---|
| Tear Trough Grade | Depth of hollow at rest and in different lighting | Volume requirement and number of sessions needed |
| Skin Quality | Thickness, laxity, and existing pigmentation | Whether shadow is structural (hollow) or pigmentary (requires other treatments) |
| Fat Pad Position | Presence of lower eyelid fat prolapse (bags) | Filler alone may worsen appearance if fat prolapse is the primary cause |
| Bone Structure | Depth of orbital rim and cheek projection | Determines injection depth and whether cheek support is needed alongside tear trough filler |
Based on clinical evaluation protocols for periorbital filler placement, drawing on peer-reviewed literature in Aesthetic Plastic Surgery and the Journal of Cosmetic Dermatology.
A critical note: Under eye filler works best when the dark appearance is caused by a hollow (structural). If dark circles are caused by melanin pigmentation in the skin itself, filler will not address the root cause. An experienced injector will assess this distinction at your consultation.
Cannula vs needle: how technique changes your result
The under-eye area is one of the highest-risk zones for filler complications because of its proximity to the angular artery and the thinness of the skin. Two injection techniques are used: needle and cannula.
Needle technique:
- Allows precise placement in very targeted areas
- Slightly higher bruising and vascular risk
- Still used by many skilled providers for specific under-eye anatomy
Cannula technique:
- A blunt-tipped flexible tube that slides through tissue rather than puncturing it
- Significantly lower bruising risk
- Reduced risk of intravascular injection
- The preferred approach in most clinics
A clinical study published in PMC comparing cannula-technique tear trough treatments found average pain scores of just 1.7 out of 10, with only one patient experiencing mild bruising and no major complications reported.
The retrospective JCAD study found that 82% of practitioners used a 27-gauge cannula technique, confirming its dominance as the current standard for safe tear trough treatment.
How long do under eye filler results last?
Standard advice from most practitioners quotes 9 to 12 months for tear trough filler duration. Recent research suggests this is conservative.
The JCAD retrospective study of 155 patients found that results persisted well beyond the commonly cited 6 to 12 month window. Significant clinical improvement was documented at 18 months post-treatment, with some patients retaining noticeable benefit at 24 months.
Factors that affect how long your results last:
- Filler product chosen: Belotero Balance, used in 23% of cases in the JCAD study, tends to integrate naturally in thin-skinned areas. Restylane Eyelight is the only FDA-approved product for periorbital use. Each product has a slightly different longevity profile.
- Volume injected: Smaller volumes metabolise faster than fuller corrections.
- Lifestyle: Aerobic exercise, sun exposure, and metabolic rate all influence how quickly the body breaks down hyaluronic acid.
- Age: Older patients tend to retain results longer as their metabolism is slower.
Most patients return for a top-up treatment at 12 to 18 months. A small touch-up of 0.2 to 0.3ml per side is often sufficient to maintain the initial result.
What can go wrong and how to spot it
The under-eye area carries specific risks that patients should understand before treatment.
Tyndall effect: The most commonly discussed under-eye filler complication. When filler is placed too superficially under thin skin, it creates a bluish tint visible through the skin. The fix is hyaluronidase dissolution, which breaks down the filler and resolves the discoloration. Choosing an injector who places filler deep to the orbicularis oculi muscle eliminates this risk.
Puffiness and overfill: Too much volume or poorly placed filler can create a puffy, swollen appearance that worsens the look of the under-eye area. This is the most common patient complaint post-treatment. Conservative initial treatment with a review appointment is safer than one large session.
Migration: Filler can spread from the placement zone over time, creating unusual contours or puffiness in adjacent areas. Thin, low-viscosity fillers like Belotero are less prone to migration in the periorbital region.
Vascular occlusion: A serious but rare complication. A PMC review of periorbital filler complications notes that ischemic events are among the rarest but most serious risks. Cannula technique and aspiration before injection are the primary safety measures used by trained injectors.
How much does under eye filler cost?
Under eye filler costs vary based on the injector's credentials, clinic location, and the filler product used.
| Factor | Typical Range |
|---|---|
| Nurse injector (per syringe) | $600 to $750 |
| Physician injector (per syringe) | $750 to $1,200 |
| Syringes typically needed | 1 to 2 (0.5 to 1ml per side) |
| Total average treatment cost | $700 to $1,400 |
| Touch-up session (12 to 18 months) | $400 to $700 |
Restylane Eyelight, the only FDA-approved filler specifically indicated for the periorbital area, is priced at the higher end of the range. Belotero Balance, widely used off-label for tear troughs due to its low viscosity and skin integration, is typically mid-range.
Price should not be the primary selection criterion for under-eye filler. The under-eye area is a high-risk zone. An experienced injector at a higher price point is safer than a discount option. The cost of correcting a complication like Tyndall effect or filler migration routinely exceeds the savings from choosing a cheaper provider initially.
How to preview your under eye filler results before treatment
The biggest challenge with under eye filler is that every patient's anatomy is different. Results from another patient's before-and-after photos give you a general sense of the treatment but cannot predict what your tear trough will look like afterward.
Makeover.so solves this with an AI-powered before-and-after preview tool. You upload a photo of your face and select your treatment area. The platform generates a photorealistic preview of your under eye filler result in under 10 seconds, based on your actual facial anatomy.
The Makeover Under Eye Preview Process:
- Upload a front-facing photo in good lighting
- Select the under eye / tear trough treatment
- View your AI-generated before-and-after preview
- Share the preview with your practitioner before your consultation
- Use the preview to align on target volume and outcome at your appointment
Practitioners using Makeover report that patients arrive at consultations with clearer expectations, reducing the gap between what was promised and what was delivered. This translates into higher satisfaction and fewer revision requests.

Choosing the right provider for your tear troughs
Tear trough treatment is not a beginner procedure. The proximity of the orbital septum, angular vessels, and the thinness of the periorbital skin require specific training and technique.
Questions to ask your provider before booking:
- How many tear trough treatments do you perform each month?
- Do you use cannula or needle technique for this area, and why?
- Which filler product do you recommend for my anatomy, and why?
- What is your protocol if I experience the Tyndall effect or excessive swelling?
- Do you have hyaluronidase on hand to dissolve filler if needed?
Avoid practitioners who offer tear trough filler at extremely low price points or who do not conduct a thorough pre-treatment assessment. The under-eye area is unforgiving. An experienced injector costs more upfront and substantially less in correction treatments.
