Under-eye skin is thin and holds fluid easily, so recovery from tear trough filler follows its own rhythm. This guide from IN Eternity Clinic on Orchard Road sets out what Dr Sin Yong tells patients to expect, day by day, and when to call.

Mild swelling and possible bruising peak over the first two to three days and usually settle within one to two weeks; the area keeps refining for about two weeks, when a review is booked. Plan important events at least two weeks after treatment.
For most people the social recovery is short and the full settling takes about two weeks. You can usually go back to desk work the same day or the next, with some swelling and perhaps a small bruise that make-up can cover after the first day. Swelling tends to be most visible on the second and third mornings, then fades over the first week.
The under-eye continues to refine for around two weeks as the gel integrates and residual swelling resolves. That is why the result is judged at a review appointment at about two weeks, not in the mirror on the evening of treatment. Plan photographs, weddings, interviews and travel at least two weeks after treatment, and longer if you bruise easily.

The lower eyelid has some of the thinnest skin on the body and a network of small lymphatic channels that clear fluid slowly. Small amounts of swelling that would be invisible on the cheek show clearly here. Hyaluronic acid also binds water to a degree, so the choice of product matters: soft gels with low water-binding are used under the eye to limit puffiness.
Placement matters as much. Product placed deep, close to the bone and beneath the orbicularis muscle, is less likely to show as a lump or as the bluish tint known as the Tyndall effect than product placed too superficially. Conservative volumes reduce the risk of a puffy ridge. Reviews of tear trough treatment consistently link restraint in volume and depth with smoother recovery. The technique used at IN Eternity Clinic is described on tear trough refinement.
“I judge an under-eye result at two weeks, not on the evening of treatment. Swelling lies; patience tells the truth.”
Day 0. Numbing cream is applied, and the hyaluronic acid used commonly contains lidocaine. Treatment takes about 15 to 20 minutes. Afterwards the area may look slightly full and feel tight; small entry marks on the cheek are normal. A cold compress, wrapped in a cloth, helps for 10 minutes at a time.
Days 1 to 3. Swelling usually peaks, especially on waking. A bruise may appear and darken. Sleep on your back with an extra pillow, avoid alcohol, saunas, hot yoga and strenuous exercise, and do not press or massage the area unless advised. Light make-up can usually be applied after 24 hours.
Week 1. Swelling falls steadily and bruising turns yellow-green. Most people look socially normal by the end of the week. Mild unevenness at this stage is often swelling rather than product.
Weeks 2 to 4. The area settles. Residual puffiness, particularly in people prone to fluid retention, can take a little longer. Normal exercise and skincare routines resume.
Review. At about two weeks, Dr Sin Yong reviews the result in the same light as before. A small top-up, or dissolving a little product, is considered only once swelling has settled.

Recovery is not the same for everyone. People who already wake with puffy eyes, or who have swelling low on the cheek that comes and goes, tend to hold more fluid after treatment and settle more slowly. Very thin, translucent lower-lid skin shows every small change in swelling and can reveal product that sits a little too high. Allergic rhinitis and eczema that make people rub their eyes prolong swelling too.
Bruising is more likely in people taking blood thinners, aspirin or certain supplements, in those who bruise easily, and when blood vessels in the area are prominent. Previous filler that has not fully broken down can add to the volume and to the swelling, which is why old product is assessed first, sometimes with ultrasound. Heat, alcohol, salty food and long flights in the first few days all make swelling worse.
None of these rules treatment out, but they change the plan: smaller amounts, a staged approach, extra time before events, or in some cases a different treatment altogether. Dr Sin Yong discusses them at assessment, so you know in advance what your own recovery is likely to look like.
Before treatment: if your doctor agrees, pause fish oil, high-dose vitamin E, ginkgo and similar supplements for several days, and avoid alcohol the day before; this reduces bruising. Do not stop prescribed blood thinners without speaking to the doctor who prescribed them. Tell the clinic about recent dental work, illness, vaccinations or cold sores.
After treatment: cold compresses in the first day, sleeping propped up, limiting salt and alcohol for a few days, and avoiding heat and strenuous exercise for 48 hours all help. Sunglasses outdoors reduce rubbing and squinting. Leave the area alone; pressing to "check" it can move product or prolong swelling.
Call the clinic the same day if you notice severe or increasing pain, skin that turns pale, white, grey or blotchy purple, or any change in vision, double vision or eye pain. These are rare signs that filler may be affecting blood flow and need immediate assessment. Spreading redness, heat or fever in the following days can indicate infection and also need prompt review.
Less urgent but worth reporting: a firm lump, a bluish tint under thin skin, or puffiness that comes and goes weeks or months later. A systematic review of delayed complications after tear trough filler describes persistent swelling, lumps and bluish discolouration, often linked to volume, depth or product. Because hyaluronic acid can be dissolved with hyaluronidase, these are manageable; if the problem is old filler placed elsewhere, see filler correction.
Allow at least two weeks before an important event, and avoid long-haul flights in the first few days if you can. If you are also having laser, radiofrequency or other injectables around the eyes, these are spaced so that swelling from one does not affect the other. Some people prefer a small first treatment with a top-up after review, which keeps the recovery lighter and the result more measured.
Tear trough filler does not suit everyone. Bulging fat, fluid-prone eyes and swelling low on the cheek can be worsened by filler. Dr Sin Yong separates these at assessment, and the non-surgical eye bag treatment guide explains the alternatives.
Mild swelling usually peaks on the second or third morning and fades over the first week, with the area settling over about two weeks. Fluid-prone eyes may take a little longer. Puffiness that comes and goes weeks later is a recognised delayed reaction and should be reported so it can be assessed.
Most people return to desk work the same day or the next. Swelling and bruising may be visible for a few days, and light make-up can usually be applied after 24 hours. If your work involves heavy physical exertion or heat, a day or two off is sensible.
Avoid strenuous exercise, hot yoga, saunas and steam rooms for about 48 hours, because heat and raised blood pressure can increase swelling and bruising. Gentle walking is fine. Return to your normal routine once swelling has settled, usually within a few days, and avoid face-down positions that press on the area for the first day or two.
Light make-up can usually be applied after 24 hours, using clean products, clean brushes and a gentle touch around the entry point. Contact lenses can generally be worn the next day if insertion does not involve pressing on the treated area. Ask the clinic if you are unsure, particularly if your eyes are watery or irritated.
Contact the clinic. Delayed swelling, small lumps and a bluish tint are recognised effects after under-eye filler, often related to the volume, the depth or the product. They are assessed in person, sometimes with ultrasound to locate the product, and hyaluronic acid can be dissolved with hyaluronidase if needed, after which the area is reviewed again.
Severe or increasing pain, skin that turns pale, white, grey or blotchy, and any change in vision, double vision or eye pain need same-day contact with the clinic. These are rare but time-sensitive. Spreading redness, heat or fever in the following days should also be reviewed promptly.
Cost depends on the amount and type of hyaluronic acid needed, whether one or both sides are treated, the technique and the review included. Under-eye treatment usually uses small volumes. IN Eternity Clinic gives a written quote after assessment. The consultation fee is waived with any medical treatment. See the under-eye filler cost guide for the factors.
