Tear Trough vs. Under-Eye: What’s the Difference?

What Is the Under-Eye Area?

The under-eye (or infraorbital area) refers to the delicate skin beneath the lower eyelid. It is one of the thinnest areas of skin on the body, making it prone to:

• Dark circles
• Hollowing
• Fine lines and crepey texture
• Puffiness

Because this area has minimal fat and very thin skin, underlying structures like blood vessels and bone can easily show through, contributing to a tired appearance.

What Is a Tear Trough?

A tear trough is a structural hollow or groove that runs from the inner corner of the eye down toward the cheek. It is not pigment—it’s a volume loss issue.

• Caused by aging, genetics, or fat loss
• Creates a shadow ? looks like dark circles
• Often mistaken for discoloration

This hollow deflects light and creates a shadow, making the under-eye appear darker and more sunken.

• Tear Trough vs. Dark Circles (Key Difference)
• Tear trough = structure (volume loss / hollow)
• Dark circles = color (pigment, vessels, or shadow)

?? Important: Many patients have a combination, which is why one treatment alone often doesn’t fully correct the area.

Types of Dark Circles & Best Treatments

1. Volume Loss (Hollow / Tear Trough)

What it looks like:

• Sunken under-eyes
• Shadowing (not true pigment)
• Tired, gaunt appearance

Cause:

Fat loss, aging, genetics

Best Treatments (Volume Correction):

• Tear trough filler (hyaluronic acid) ? restores lost volume
• PRF / EZ Gel ? natural collagen stimulation + subtle volume
• Biostimulatory treatments (Sculptra, polynucleotides)

?? Filler works best here because it directly corrects the hollow causing the shadow.

2. Pigmented Dark Circles (Brown / Gray)

What it looks like:

• Brown or gray discoloration
• Does NOT improve with stretching the skin

Cause:

• Excess melanin
• Sun damage
• Post-inflammatory pigmentation

Best Treatments (Rejuvenation):

• Chemical peels (Cosmelan, light peels)
• Laser treatments
• Medical-grade skincare (vitamin C, retinol, SPF)
• Microneedling with exosomes

?? Filler will NOT fix this type because the issue is pigment, not structure.

3. Vascular Dark Circles (Blue / Purple)

What it looks like:

• Blue, purple, or reddish tones
• May improve when you press the area

Cause:

• Visible blood vessels under thin skin
• Poor circulation, fatigue, allergies

Best Treatments (Skin Quality + Circulation):

• PRF / PRP ? improves skin thickness & color
• Exosome microneedling
• Laser (vascular lasers)
• Topicals with caffeine or vitamin K

?? Goal: thicken the skin and reduce visibility of vessels.

4. Skin Laxity & Crepey Under-Eyes

What it looks like:

• Fine lines, wrinkles
• Thin, crepey texture
• Mild shadowing

Cause:

• Collagen loss
• Aging, dehydration

Best Treatments (Tightening):

RF microneedling (Morpheus8, etc.)

Tixel or laser resurfacing

PRF / skin boosters

?? This is a tightening problem, not volume or pigment.

5. Puffy Under-Eyes (Fat Pads / Bags)

What it looks like:

• Bulging or swelling
• Shadow underneath the puffiness

Cause:

• Fat herniation
• Fluid retention

Best Treatments:

• PRF (mild cases)
• Lifestyle changes (salt, sleep, allergies)
• Lower blepharoplasty (severe cases)

?? Filler can make this worse if not properly selected.

Under-Eyes That Need Volume

Tear trough filler

PRF EZ Gel

? Restores structure and eliminates shadowing

Under-Eyes That Need Tightening

RF microneedling

Tixel

? Improves crepey skin and laxity

Under-Eyes That Need Rejuvenation

PRF / exosomes

Medical-grade skincare

? Improves color, texture, and skin quality

Why a Combination Approach Works Best

• Dark circles are rarely just one issue. Most patients have:
• A little volume loss
• Some pigment or vascular show-through
• Early skin thinning

That’s why the best results come from layering treatments:

• Structure (filler)
• Skin quality (PRF/exosomes)
• Surface correction (lasers/peels)

Final Takeaway

Treating the under-eye is not about “one fix”—it’s about diagnosing the cause:

Hollow? ? add volume

Dark pigment? ? brighten

Blue/purple? ? improve skin quality

Crepey? ? tighten

When done correctly, under-eye treatments don’t just reduce dark circles—they create a rested, refreshed, and naturally youthful appearance.
