Under-eye fillers are one of the most popular cosmetic procedures in Korea, especially among international patients who want to brighten dark circles, smooth hollowness, and refresh tired eyes without surgery.
A key question patients ask during consultations is:

“How many CCs do I need for my under-eye fillers?”

The answer depends on your anatomy, degree of hollowness, skin thickness, and whether both sides need the same amount. Here’s a clear breakdown to help you understand typical volumes and what to expect during your visit to a Korean skin clinic.

1. Typical Amount of Filler Needed Under the Eyes

Most patients require:

➡ 0.5–1cc per side

or

➡ 1–2cc total for both eyes

This is the standard range used in Korean clinics.

2. Why the Amount Varies From Person to Person

A. Degree of Tear Trough Hollowing

• Mild hollow → 0.3–0.5cc per side
• Moderate hollow → 0.5–0.8cc per side
• Deep hollow → 0.8–1cc per side

B. Skin Thickness

Thicker skin can hold slightly more product; thinner skin requires caution to avoid puffiness.

C. Filler Type Used

Soft, flexible HA fillers (e.g., Chaeum 1, Restylane Eyelight, or Volbella) integrate well and require lower volume.

D. Under-Eye Shadow vs Hollowness

Not all dark circles are caused by hollowing—pigmentation and skin texture also matter.

3. Why Korean Clinics Often Use Less Filler

Korean clinics prioritize:

• Natural results
• Minimal swelling
• Avoiding puffiness (Tyndall effect)
• Micro-layer placement
• Multi-step approach

Rather than injecting a full 1cc right away, many Korean doctors prefer:

“Layering Technique”

Start with 0.3–0.5cc → reassess → add more only if needed.

This produces smoother, more even results.

4. When You Might Need More CCs

You may require 1–1.5cc per side if:

• You have deep hollowness
• You’ve lost mid-cheek volume
• You’ve had aging-related volume decline
• You need midface support (malar filler)

In these cases, the clinic may recommend combining tear trough fillers with midface/cheek fillers to support the under-eye.

5. What Happens If You Inject Too Much?

Overfilling leads to:

• Puffiness
• Water retention
• Under-eye swelling
• Blue tint (Tyndall effect)
• Irregular texture

Korean specialists typically avoid this by using conservative amounts and building up slowly.

6. How Long Do Under Eye Fillers Last?

In Korea, most soft HA fillers last:

9–18 months

With natural metabolism depending on:

• Lifestyle
• Sleep
• Stress
• Hydration
• Filler brand
• Placement depth

7. How Much Does Under Eye Filler Cost in Korea?

Typical pricing in Seoul:

• ₩250,000–₩600,000 per 1cc
  (depends on brand and clinic)

Premium imported fillers (Restylane, Juvederm) cost more than Korean brands (Chaeum, Yvoire, etc.).

8. Treatment Flow in Korean Clinics

1. Consultation & Diagnosis

Assess hollowness, pigmentation, ligament support.

2. Numbing / Ice

For comfort.

3. Cannula Treatment

Most Korean clinics use cannulas to minimize bruising.

4. Micro-layer Injection

Small amounts placed precisely.

5. Aftercare

Ice packs, no heavy exercise, no sauna for 24 hours.

Entire process takes 10–20 minutes.

Final Answer: How Many CCs?

Most patients need 1–2cc total for natural under-eye correction in Korea.

Breakdown:

• Mild: 0.5–1cc total
• Moderate: 1–1.5cc total
• Severe: 1.5–2cc+ total (with cheek support)

Korean clinics focus on subtle, natural improvements, so expect a conservative and safe approach.
