Under-eye dark circles are misdiagnosed constantly. The same shadowy look can come from three completely different causes — and each needs a different treatment. Filler everyone is the wrong answer.
This guide covers the diagnostic logic, the treatment for each type, and what doesn't work.
Type 1: Pigmentation (melanin)
If skin under the eye is darker than surrounding skin even when stretched flat, the cause is excess melanin. Common in Latin and South Asian skin. Hereditary in many cases.
Treatment: picosecond laser pigmentation protocol (S/300 ~US$86 per session at Elyzea), topical retinoids, sun protection. 4-6 sessions typical.
Filler in this case will worsen the appearance — under-eye HA shows blue (Tyndall effect) over pigmented skin.
Type 2: Tear-trough hollowness
If pulling skin down deepens the hollow and creates a shadow, the cause is a structural depression at the orbital rim. The skeletal structure is anteriorly positioned creating a shadow.
Treatment: tear-trough filler with HA (~US$243/syringe at Elyzea). Critical: must be performed by an experienced injector — vascular complications in this zone are serious.
1 syringe per visit. Build conservatively.
Type 3: Vascular shadowing
If the under-eye area looks blue/purple due to thin skin showing veins beneath, that's vascular shadowing. Genetic component significant.
Treatment: skin-thickening with Profhilo or biostimulators, plus possible vascular laser. Filler can paradoxically worsen this if placed superficially.
Multiple treatments often needed for partial improvement; complete resolution rare.
Mixed cases
Most patients have a combination. The diagnostic test is the stretch test: stretch the skin flat. If darkness remains = pigmentation. If a shadow remains = hollowness. If you see veins = vascular.
Combination protocol: address pigmentation first (4-6 picosecond sessions), then assess remaining shadowing for filler vs Profhilo decision.
What doesn't work
- Eye creams alone (rarely make meaningful difference)
- Caffeine cooling rollers (temporary cosmetic only)
- Filler when the cause is pigmentation or vascular
- Lasers without diagnostic clarity (wrong type of laser worsens many cases)
Cost summary
| Cause | Treatment | Elyzea cost |
|---|---|---|
| Pigmentation | Picosecond × 4–6 | ~US$345–$520 |
| Hollowness | Tear-trough filler 1 syringe | ~US$243 |
| Vascular | Profhilo × 2 | ~US$560 |
| Combined approach | All three over 6 months | ~$1,200-$1,500 |
Pre-treatment assessment
What to expect at consultation:
- Skin stretch test to identify pigmentation vs hollowness
- Photo documentation under different lighting
- Skin quality assessment (thinness, vascular pattern)
- Discussion of family history (genetic component)
- Customized multi-modal protocol if warranted
Aftercare considerations
Each treatment has specific aftercare:
- Picosecond: SPF 50+ daily, no sun exposure, sleeping at slight elevation
- Tear-trough filler: avoid blood thinners pre, hydrate, no exercise 24h, no salt-heavy meals
- Profhilo: avoid heat, no exercise 24h, sleeping at slight elevation
Frequently asked questions
Will tear-trough filler look natural?
Conservative dosing (1 syringe), proper depth (preosteal), and product choice produce natural results.
Can I dissolve tear-trough filler?
Yes. Hyaluronidase reverses HA filler within 24-48 hours.
Do dark circles return after picosecond?
If sun exposure resumes, yes. Lifelong sun protection essential.
Is genetic dark circles fixable?
Improvable but not eliminable. Realistic expectations key.
Will sleep fix this?
Sleep helps slightly but doesn't address structural causes.
Is vitamin K cream effective?
Limited evidence for clinical-grade effect.
What about red light therapy?
Mild improvement for some vascular components. Not a primary treatment.
Bottom line
Diagnosis first, treatment second. Stretch test identifies pigmentation vs hollowness vs vascular. Picosecond for pigmentation; filler for hollowness; Profhilo or biostimulator for vascular. Lima costs are dramatically below US for all three modalities.
