Tear Trough Filler Aftercare & Swelling Timeline: What to Expect

Tear trough filler has become one of the most effective non-surgical treatments for reducing under-eye hollows, dark circles, and signs of fatigue.

While results can be transformative, understanding proper aftercare, the typical swelling timeline, and how to optimise recovery is essential for natural, long-lasting outcomes.

At Dr Hass Clinic, we combine meticulous technique with patient education to ensure safe, balanced, and aesthetically pleasing results. Tear trough treatment is highly precise due to the delicate under-eye anatomy, making post-procedure guidance especially important.

The tear trough is the groove that runs from the inner corner of the eye diagonally beneath the lower eyelid towards the mid-cheek. As we age, or due to genetics, volume loss in this area can create a shadowed, hollow appearance, making the eyes appear tired, older, or sunken.

Tear trough fillers are typically made from hyaluronic acid, a naturally occurring substance in the skin. When expertly injected beneath the thin under-eye skin, these fillers restore lost volume, smooth contours, and reduce shadowing. The objective is never to “plump” the area unnaturally, but to enhance natural anatomy, improve under-eye transitions, and subtly refresh the appearance.

The under-eye area is particularly delicate, with minimal fat and very thin skin. Precise placement is critical, as incorrect technique or overfilling can lead to puffiness, uneven contours, or the “Tyndall effect,” where the filler appears bluish under the skin. This is why expert assessment, conservative technique, and individualised treatment planning are essential for achieving natural results.

Recovery from tear trough filler is generally straightforward, but following aftercare instructions can make a significant difference in both comfort and outcome.

Immediate Aftercare (First 24–48 Hours)

After treatment, it is normal to experience mild swelling, tenderness, or redness. Applying a gentle, cold compress can reduce discomfort, but pressure or massage should be avoided. Keeping your head elevated when resting or sleeping helps minimise fluid accumulation.

It is important to avoid rubbing or touching the under-eye area, as this can displace the filler. Strenuous exercise, alcohol consumption, or activities that increase blood flow to the face should be postponed for at least 24–48 hours. Similarly, facial treatments such as chemical peels, microneedling, or laser resurfacing should be avoided during this period.

Ongoing Aftercare (First Week)

Swelling may peak over the first few days, and minor bruising is not uncommon, particularly in patients with thinner skin or sensitive vasculature. During this stage, gentle skincare is recommended, avoiding strong acids or retinols.

Sun protection is essential. The under-eye skin is delicate, and UV exposure can exacerbate pigmentation or shadowing, even during early healing.

Swelling after tear trough filler follows a predictable course, although individual experiences vary. Here’s a typical timeline:

• Day 0–1: Mild to moderate swelling and tenderness. Some redness may be visible at injection points.
• Day 2–3: Swelling often peaks. Minor bruising may appear as the blood under the skin oxidises. Cold compresses and head elevation are most effective during this period.
• Day 4–7: Swelling gradually decreases. Bruising fades, and under-eye contours begin to appear more defined.
• Week 2: Most swelling and bruising have resolved. Subtle contour adjustments continue, and results become increasingly natural.
• Week 3–4: Results are typically fully settled. Any minor residual swelling or asymmetry can be assessed for touch-ups if required.

Tip: Patients with thinner under-eye skin or slower healing may notice swelling slightly beyond the first week. This is normal, and results will continue to refine over several weeks.

The under-eye area is delicate, so small adjustments in aftercare can make a significant difference:

• Avoid pressure: Sleeping on your back with your head slightly elevated helps minimise swelling.
• Gentle skincare only: Avoid exfoliants, retinols, or harsh acids for at least 3–5 days post-treatment.
• Sun protection: Broad-spectrum SPF helps prevent pigmentation changes during recovery.
• Follow-up consultation: A review 2–4 weeks after treatment allows assessment of settling, symmetry, and any minor touch-ups.

Tear trough fillers are generally very safe, but contact your practitioner immediately if you notice:

• Significant or increasing pain
• Lumps or uneven areas that do not improve
• Redness, warmth, or signs of infection
• Visual changes, such as blurred vision or flashes of light (rare but urgent)

At Dr Hass Clinic, all procedures are performed under strict safety protocols, and any concerns are managed promptly and effectively.

• Tear trough fillers typically last 9–12 months, depending on filler type, metabolism, and individual anatomy.
• Maintenance treatments help preserve under-eye volume and prevent shadows from reappearing.
• Conservative touch-ups are preferred to avoid overfilling, which can lead to puffiness or unnatural contours.

Tear trough fillers offer a subtle yet transformative way to refresh the under-eye area, reduce hollows, and restore a more youthful, well-rested appearance. Recovery is usually straightforward, but understanding aftercare, swelling, and timing is key to achieving the best results.

At Dr Hass Clinic, we guide each treatment by precise anatomical knowledge, careful technique, and a commitment to natural, balanced outcomes. When aftercare instructions are followed correctly, tear trough fillers can provide a rejuvenated, harmonious under-eye appearance without compromising facial aesthetics.
