Aegyo Sal Filler: How to Get the Korean Under-Eye Charm



Aegyo Sal refers to the subtle roll of muscle just beneath the lower lash line that becomes prominent when smiling. Unlike eye bags, which are age-related fat protrusions that make you look tired, aegyo sal is a sign of youth and vitality. In Korean beauty culture, aegyo sal is considered essential for the “sweet eye” look. Seoul’s Rappoel Dermatology uses low-viscosity The Chaeum filler in micro-amounts (0.3-0.5cc total) to sculpt natural aegyo sal.

Aegyo Sal vs Eye Bags: What Do You Actually Need?

  • Aegyo Sal: Located directly below lower lashes, 3-5mm wide, prominent when smiling, makes eyes appear larger and sweeter
  • Eye Bags: Located below aegyo sal, bulging appearance, present even without smiling, makes you look older and tired
  • Tear Troughs: Depressed shadow extending from inner corner downward, makes you look haggard
  • Correct Approach: Fill aegyo sal for under-eye softness; address eye bags differently; fill tear troughs with deep structural support

Rappoel’s Aegyo Sal Filler Technique

  1. Pre-treatment Design: The doctor asks you to smile repeatedly, marking the natural prominence of the aegyo sal to ensure natural-looking results
  2. Material Selection: Low-viscosity, high-ductility The Chaeum filler for soft touch and no lumping
  3. Injection Technique: Continuous linear threading along the aegyo sal contour, only 0.15-0.25cc per side
  4. Immediate Shaping: Doctor gently molds the filler immediately after injection for smooth, symmetrical lines
  5. Total Time: About 15-20 minutes, minimal downtime
  6. Duration: Typically 6-9 months, as under-eye area metabolizes filler faster

Ideal Candidates

  • Naturally lacking visible aegyo sal, wanting under-eye softness
  • Eyes that are small or long, wanting to shorten eye proportions
  • Flat under-eye area lacking dimension when smiling
  • Previously had aegyo sal that has thinned with age
  • Wanting natural results that don’t look “done”

Aegyo sal filler is one of the most “less is more” procedures in Korean aesthetics. Anything over 0.5cc total tends to look unnatural or even turn into “fake eye bags.” Rappoel Clinic is located 3 minutes from Gangnam Station Exit 10. The doctors have deep understanding of Korean beauty aesthetics and design the most suitable aegyo sal shape based on your eye and face proportions.

Frequently Asked Questions

What is the difference between aegyo sal filler and tear trough filler?
Aegyo sal filler is injected into the superficial layer just below the lower lash line to create the natural muscle roll that appears when smiling, making eyes look sweeter and younger. Tear trough filler is injected deeper to fill the tear trough depression, eliminating dark circles and hollow appearance. The two are at different locations and serve different purposes; some people benefit from both for optimal results.
Can aegyo sal filler turn into eye bags?
As long as the injection amount stays within 0.15-0.25cc per side and the injection layer is correct (superficial, just below the lashes), it will not turn into eye bags. The common problem is when inexperienced clinics inject too much or too deep, causing the entire under-eye area to bulge. Choosing an experienced Korean dermatologist prevents this issue.
Is aegyo sal filler painful?
Since under-eye skin is thin, a topical numbing cream is applied for 15-20 minutes first. The injection uses an ultra-fine needle, and pain is minimal. Most patients describe it as mild pinching. The entire procedure takes 15-20 minutes.
How soon can I see results?
Results are visible immediately, but the best appearance comes after 1-2 weeks when swelling subsides. Mild swelling may last 1-2 days. Avoid rubbing your eyes, strenuous exercise, and alcohol for 48 hours.
