Aegyo-sal filler and under-eye filler both inject hyaluronic acid filler into the area below the eyes, but the intended change and the exact injection site differ. Aegyo-sal filler adds volume to the aegyo-sal (the small fold of fullness just under the eyes) to create the impression of larger, younger-looking eyes. Under-eye filler focuses on replenishing volume in hollowed areas and dark circle zones so that tired-looking eyes look fresher. The two procedures may be performed separately or, depending on the consultation, combined.
Why Can Aegyo-sal Filler Make Eyes Look Bigger?
The aegyo-sal, which naturally puffs up under the eyes when you smile, makes the eyes look visually taller. If this area is flat or lacks volume, the expression can look flat and the overall impression can come across as cold.
Aegyo-sal filler creates this volume by injecting a small amount of filler into a shallow layer just below the eye, above the tear trough. Because the amount is small and the placement needs to be precise for a natural result, finely controlling the injection layer and amount is the key.
What Concerns Does Under-Eye Filler Address?
Under-eye hollowing occurs when the tear trough deepens with age or when there is little subcutaneous fat. When this area is sunken, it casts a shadow that looks like dark circles and gives an overall tired or older impression.
Under-eye filler works by replenishing volume in the sunken area to reduce the shadow and bring life back to the eye area. The injection site is deeper than for aegyo-sal filler and covers a wider range.
Can the Two Procedures Be Done on the Same Day?
The two fillers are sometimes combined on the same day, but because the areas are adjacent, the amount injected in one can affect the result of the other. For this reason, it is generally said that treating one area first, checking the result and then adding the other makes the outcome easier to predict.
Similar principles apply when Botox and filler are combined. The usual order is to give Botox first and add filler 7 to 14 days later, but if time is limited, doing both on the same day is also possible. The order and interval vary depending on the area and your individual condition, so they are decided at the consultation.
What Should You Check Before Filler Treatment?
The under-eye area is densely packed with blood vessels and nerves. Before injection, it is necessary to assess your under-eye fat bulge, skin thickness and blood vessel pathways. If the under-eye fat already bulges noticeably, adding filler may actually make the area look puffier, and in that case the treatment itself may not be suitable.
- Check whether the under-eye fat (orbital fat) protrudes
- Distinguish whether the dark circles are vascular, pigment-related or tone-related
- Whether you take antiplatelet drugs or anticoagulants (higher risk of bruising)
- History of previous filler treatment and whether any filler remains
- Whether you are pregnant or breastfeeding
At Repic Clinic in Gangnam (B1–B2, 318 Gangnam-daero, Gangnam-gu, Seoul), these items are reviewed at the consultation before treatment, and suitability and method are then explained. You can find more details on the official page.
What Should You Watch for After Treatment?
Right after filler treatment in the under-eye and aegyo-sal areas, bruising, swelling and temporary tenderness may occur. Most of these ease within a few days, but pressing hard on or massaging the treated area during this period can cause the filler to move, so it is best to avoid doing so. Heavy drinking and saunas on the day of treatment can also worsen swelling.
In rare cases, vascular compression or overcorrection of the filler may occur, and if unusual symptoms (severe pain, skin color changes, vision problems) appear, you should contact a medical facility immediately. It is also good to know that hyaluronic acid filler can be dissolved with an enzyme (hyaluronidase) injection if necessary.
Frequently Asked Questions (FAQ)
How do aegyo-sal filler and under-eye filler differ?
Aegyo-sal filler injects a small amount of filler into the aegyo-sal area just below the eyes to create volume so that the eyes look larger and livelier when you smile. Under-eye filler focuses on filling hollowed areas such as the tear trough to improve shadows and dark circles. Because the injection site and purpose differ, it is a good idea to first check at a consultation which is more suitable.
How long does aegyo-sal filler last?
How long hyaluronic acid filler lasts depends on the type of product, the amount injected and your individual metabolism, so it is hard to give a single answer. It is generally said to last around 6 to 12 months, but the actual duration varies from person to person. Please confirm the expected duration at your consultation.
My under-eye area is somewhat puffy. Can I still get under-eye filler?
If the under-eye fat (orbital fat) already protrudes, adding filler may actually make the area look puffier. In this case, under-eye filler may not be suitable, so checking the structure of the under-eye area before treatment is generally necessary. At the consultation, the degree of protrusion and the cause of the dark circles are evaluated together before deciding on a direction.
Can I get Botox and under-eye filler on the same day?
Same-day treatment is also possible. Botox relaxes muscles while filler adds volume, so their mechanisms of action do not overlap. However, when both are applied to the same area at the same time, it can affect how the filler is distributed, so giving Botox first and adding filler 7 to 14 days later makes the result easier to predict. If time is limited, a same-day plan can also be designed, and the order is decided at the consultation.
How long does bruising last after filler treatment?
The under-eye and aegyo-sal areas have many blood vessels, so bruising may occur after treatment. Most bruises fade naturally within 3 to 7 days, but they may last longer depending on your blood vessel condition or the medications you take. You should generally tell your doctor before treatment if you take antiplatelet drugs or anticoagulants.
How much does aegyo-sal filler cost?
The scope and cost of combined procedures can be explained after a consultation.
Can I return to daily life right after under-eye filler?
Light daily activities are possible for most people right after treatment. However, it is best to avoid strenuous exercise, drinking and saunas on the day of treatment, and pressing hard on or massaging the treated area can cause the filler to move, so caution is needed. If unusual symptoms (severe pain, skin color changes, vision problems) occur, contact the clinic immediately.
