The under-eye area is one of the most delicate parts of the face—and also one of the first to show aging. Fine lines, dark circles, hollowness, puffiness, and crepey texture can make you look tired even when you’re well-rested.

Korea offers some of the world’s most advanced under-eye rejuvenation treatments, combining skin boosters, collagen stimulators, fillers, lasers, and tightening devices to restore a youthful, bright, and smooth look.

This guide breaks down every major under-eye treatment used in Korean dermatology, what it treats, and how to choose the right option for your concerns.

1. Rejuran I: Best for Thin, Crepey Under-Eye Skin

Rejuran I is a specialized polynucleotide (PN) formula designed for thin and fragile tissue.

Best For

• Crepey texture
• Early fine lines
• Weak or damaged skin
• Mild dark circles from thin skin

Benefits

• Strengthens the skin barrier
• Improves elasticity
• Smooths micro-wrinkles
• Natural, subtle improvement

Rejuran I does not add volume—it focuses purely on skin quality.

2. Juvelook: Best for Elasticity & Gentle Collagen Lifting

Juvelook combines hyaluronic acid with a collagen-stimulating polymer.
It firms the lower eyelid area and improves textural issues.

Best For

• Fine to moderate wrinkles
• Mild under-eye sagging
• Loss of elasticity
• Rough or uneven texture

Benefits

• Stimulates collagen
• Visibly firms the lower eyelid
• Smooths lines and improves density

A great option when skin is loose but not severely hollow.

3. Under-Eye Filler: Best for Hollows & Tear Troughs

Hyaluronic acid filler is the go-to treatment for under-eye hollowness.

Best For

• Deep tear troughs
• Volume loss
• Shadowing
• Tired or sunken appearance

Benefits

• Immediate improvement
• Smooths the transition from eyelid to cheek
• Reduces dark shadows

Korean dermatologists use very soft, low-density fillers to avoid puffiness and unnatural results.

4. Exosome Under-Eye Booster: Best for Glow + Repair

Exosomes deliver regenerative cellular signals that improve elasticity, texture, and brightness.

Best For

• Dullness
• Fine lines
• Mild pigmentation
• Post-laser healing

Benefits

• Fast skin repair
• Hydration and glow
• Improved resiliency

Exosomes often pair well with laser or microneedling under-eye treatments.

5. PRP (Platelet-Rich Plasma): Best for Natural Regeneration

PRP uses your own plasma to stimulate collagen.

Best For

• Crepey skin
• Early wrinkles
• Under-eye fatigue
• Mild discoloration

Benefits

• Natural regeneration
• Gradual tightening
• Good for sensitive skin

Ideal for patients who prefer a natural treatment without added fillers or synthetic boosters.

6. Laser Toning: Best for Pigment-Based Dark Circles

Korean clinics commonly use gentle lasers to brighten under-eye pigmentation.

Best For

• Brown discoloration
• Long-term pigmentation
• Sun-related dark circles

Benefits

• Gradual brightening
• Smooths texture
• Safe for most skin types

Often combined with Rejuran I for both pigmentation + texture improvement.

7. Infraorbital HIFU: Best for Tightening Loose Skin

HIFU devices such as Shurink, Liftera, and Ultraformer are used cautiously in the under-eye area.

Best For

• Mild lower-lid sagging
• Early skin laxity
• Softening fine wrinkles

Benefits

• Firming effect
• Improved tightness
• No filler volume needed

Used at low energy to avoid excessive fat reduction.

8. Radiofrequency Microneedling: Best for Wrinkles & Texture

Devices like Potenza or Scarlett RF improve texture and stimulate collagen.

Best For

• Crepey texture
• Fine lines
• Slight under-eye laxity

Benefits

• Tightens and smooths
• Boosts collagen
• Enhances skin density

Often paired with exosomes or Rejuran for enhanced healing.

9. Fat Grafting: Best for Severe Volume Loss

For deeper hollowness or aging, micro-fat grafting offers a natural, long-lasting approach.

Best For

• Significant tear trough hollows
• Midface deflation
• Age-related volume loss

Benefits

• Long-lasting volume
• Natural, soft appearance
• Can improve skin quality due to stem cells in fat

This is typically performed in plastic surgery clinics rather than dermatology clinics.

10. Lower Blepharoplasty: Best for Eye Bags or Structural Issues

Surgery is recommended if under-eye aging is caused by:

• Fat bulging
• Loose lower-lid muscles
• Excess skin
• Severe sagging

Benefits

• Removes or repositions fat
• Tightens muscles
• Smooths under-eye contour

Often combined with fat repositioning for a smooth, youthful look.

Which Under-Eye Treatment Should You Choose?

Here’s the Korean approach based on top concerns:

Crepey, thin skin

→ Rejuran I or Exosomes

Loose skin with early wrinkles

→ Juvelook or HIFU (low energy)

Hollows / tear troughs

→ Soft filler or fat grafting

Dark circles from pigmentation

→ Laser toning + Rejuran I

Dull, tired appearance

→ Skinvive-style hydration boosters or Exosomes

Severe eye bags

→ Lower blepharoplasty

Best all-around skin improvement

→ Rejuran I + Juvelook combined over time

Korean Combination Approach (Most Effective)

Korean dermatologists rarely rely on a single treatment.
A typical rejuvenation plan may involve:

• Rejuran I for skin strength
• Juvelook for elasticity
• Filler only if volume is missing
• Laser toning for pigmentation
• Exosomes for glow and repair

This layered method restores natural, youthful under-eyes without looking overfilled.
