Fillers
Aegyo-Sal (Eye Smile) Filler
Aegyo-sal — often called the "eye smile" or love band — is the soft ridge of volume that sits just beneath the lower lash line and becomes more pronounced when you smile.
Procedure time
Within about 30 minutes
Anesthesia
Topical ointment anesthesia (local anesthesia if needed)
Lasts
Domestic: 6–12 months; Imported: 12–18 months
Downtime
Minimal, but because the lower-lid skin is very thin, mild swelling or a small bruise can appear for a few days; it is easily covered with concealer and usually settles within about a week
Overview
Description
Aegyo-sal — often called the "eye smile" or love band — is the soft ridge of volume that sits just beneath the lower lash line and becomes more pronounced when you smile. When this band is flat or has thinned with age, the eyes can read as plain, tired or older than they are. Aegyo-sal filler places a small, precisely measured amount of hyaluronic acid directly under the lash line to rebuild that gentle curve, so the eyes can look livelier and more expressive when you smile. At HERA the design is planned 1:1 around your eye shape, lower-lid width and existing under-eye contour, and placed with a fine blunt-tip micro-cannula to help minimize bruising and swelling. The aim is a soft, believable band that moves naturally with your expression — never the overfilled ridge that results from placing too much product.
Why it works
The essentials, at a glance
High-Purity, Safe Filler
We use KFDA- and FDA-approved hyaluronic-acid fillers to minimize the risk of side effects in this delicate area.
Minimal Bruising & Swelling
A blunt-tip micro-cannula is used to reduce pain, bruising and swelling around the thin lower-lid skin.

1 Custom Design: Volume and width are planned around your own eye shape so the band reads as natural rather than added on.
Treatment Areas
Treatment Areas
Each area is planned separately, based on your anatomy.
Lower Lash Line (Aegyo-Sal)
Rebuilds the soft band of volume directly beneath the lashes so the eyes look livelier when you smile.
Aegyo-Sal Fine Lines
Softens the fine creases that form across the band and can add years to the impression.
Balance with the Tear Trough
Where a hollow sits below the band, volume is balanced so the aegyo-sal reads clearly instead of blending into the shadow.
Who it's for
Recommended For
Where filler tends to make the most visible difference.
- Flat or hollow under-eye area giving a plain, expressionless look
- Dark circles that make the overall impression look dull and heavy
- Wanting added under-eye volume for a younger, livelier appearance
- Fine wrinkles across the aegyo-sal area that add years to the face
- Dissatisfied with previous aegyo-sal filler that looked overfilled
Your visit
How the Procedure Works
What happens on the day, from consultation to aftercare.
01
Consultation & eye analysis — a HERA doctor examines your eye shape, lower-lid width and whether a tear-trough hollow is also present.
02
Design & marking — the band's width and volume are mapped 1
1 so the result suits your own smile rather than a template.
03
Anesthesia — topical numbing cream is applied for a comfortable procedure in this sensitive area.
04
Cannula filler injection — high-purity HA is placed at the correct depth using a blunt-tip micro-cannula to limit bruising.
05
Shaping & expression check — the doctor molds the filler and asks you to smile, confirming the band moves naturally and both sides match.
06
Aftercare guidance — cold-care and precautions are explained, and you can return to daily life right away.

Frequently asked questions
Frequently asked questions
Answers to the questions international patients ask us most.
What is the difference between aegyo-sal filler and under-eye (tear trough) filler?
They solve opposite problems. Tear-trough filler fills the hollow groove below the eye to remove shadow and dark circles. Aegyo-sal filler builds a small ridge of volume directly under the lash line so the eyes look livelier when you smile. Some patients need only one; others benefit from both, balanced together so the band reads clearly instead of blending into the hollow.
Will it look obvious or overfilled?
That depends entirely on dose and placement. The overfilled, sausage-like ridge people worry about comes from placing too much product, or placing it too superficially. At HERA the band is designed around your own lower-lid width and checked while you smile, so it moves with your expression.
How long does aegyo-sal filler last?
Generally 6–12 months with domestic fillers and 12–18 months with imported products, though this varies with the amount placed, your metabolism and how expressive the area is. Because the lower lid moves constantly, this area tends to metabolize filler a little faster than static areas.
Does it hurt, and can I go back to work the same day?
Topical numbing cream is applied first and a blunt-tip micro-cannula is used, so most patients describe pressure rather than sharp pain. You can return to daily life right away. Mild swelling or a small bruise can show for a few days and is easily covered with concealer.
Can it be dissolved if I don't like the result?
Yes. Hyaluronic acid filler is reversible with an enzyme called hyaluronidase. If the band is heavier than you wanted, or has settled unevenly, it can be dissolved and re-treated after the tissue has stabilized. Adding more filler on top of a result you dislike almost always makes it worse.
