GANGNAM HERA
Aegyo-Sal (Eye Smile) Filler

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 minimise 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

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

Precisely targeted and placed, tailored to your anatomy and goals.

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

A versatile treatment — here's where it makes the biggest 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

A calm, guided sequence from first consult 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.

I recently visited Hera Gangnam for a more intensive lifting treatment, and I couldn't be happier with the experience. As someone who had only done basic toning and hair removal before, I was incredibly nervous about trying actual "lifting" lasers, but this clinic put me completely at ease. ​What sets Hera apart is their thoroughness. I had two separate consultations: ​Consultation Manager (상담실장님): She was incredibly kind and helped map out my concerns without being pushy. ​Head Doctor (원장님): He provided a deep dive into the technical side, ensuring I understood exactly how the treatments would work for my face shape. ​I focused on two specific areas to tackle my double chin and overall facial contour: ​10Thera Lifting: A game-changer! The procedure was much more comfortable than I expected. It does hurt a lot but apparently not as bad as Ulthera. The staff members and the doctor would check on me the whole time to make sure the treatment is not too awfully painful. ​Sok-Pae Injection (쏙빼주사): Targeted specifically at my double chin area. ​ ​The entire staff is knowledgeable, professional, and most importantly, they actually listen and care for my needs. I’m already seeing a difference (I might need two more sessions in a couple of months) and am definitely coming back for my forehead and jaw Botox next time! ​Highly recommended if you're a "lifting newbie" looking for a trustworthy clinic in Gangnam.

I recently visited Gangnam Hera Clinic for a Titanium Lifting treatment, and the entire experience genuinely exceeded my expectations. The staff were incredibly warm and welcoming, immediately putting me at ease the moment I walked in. They explained every part of the procedure clearly and thoroughly, making sure I knew exactly what would happen and how to prepare. Although I’d heard that lifting treatments can be uncomfortable, this one was surprisingly manageable. The doctor checked in with me constantly and even took short breaks to make sure I wasn’t feeling any pain, which I really appreciated. The whole process was smooth, well-organised, and very professional. I could tell they were attentive and meticulous from start to finish. The clinic itself is spotless, modern, and honestly one of the best I’ve visited in Seoul!

💖 Visit to Hera Gangnam Clinic: Absolutely Recommended! I visited the Hera Gangnam Clinic today and was pleasantly surprised by how friendly and accommodating everyone was—from the staff and doctors right up to the boss. I received excellent consultation because I wanted to get lip fillers, and achieving symmetry was especially important to me. The attending physician held a very detailed consultation with me and fulfilled all my wishes perfectly. I am super satisfied with my lips already and can hardly wait to see the final result once the swelling has gone down. I will definitely be back! I wholeheartedly recommend this clinic to all foreigners coming to Korea. The entire team speaks several languages, so you don't have to worry about not being understood.🙌🏻

I recently tried the Rejuran treatment at Gangnam Hera Clinic, and I honestly had such a great experience. Before starting, the doctor carefully explained everything to me and recommended the version of Rejuran that would suit my skin best. I had heard that this treatment can be quite painful, but honestly, it was completely manageable. The staff was incredibly warm and welcoming from start to finish. They checked on me throughout the process and made sure I felt comfortable the entire time. The follow-up was also really professional, and they made sure I understood how to take care of my skin afterwards. Overall, I really recommend Gangnam Hera Clinic if you’re thinking about getting Rejuran. It was a smooth, reassuring, and positive experience. ✨

This was my second time visiting Gangnam Hera after returning from the States, and once again, I’m so impressed. The staff are friendly, professional, and genuinely attentive. The clinic is exceptionally clean and modern, with a relaxing atmosphere that makes every visit comfortable. The prices are very reasonable, but what truly stands out is the quality of care and the amazing results. It’s a top-quality dermatology clinic that I would absolutely recommend to my friends and anyone looking for trusted, high end skincare in Korea.

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 metabolise 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 stabilised. Adding more filler on top of a result you dislike almost always makes it worse.
