Under-Eye Treatment Guide: Fillers, PRP, Surgery & More

The under-eye area is one of the first regions of the face to show visible signs of aging — and one of the most challenging to treat effectively. The skin beneath the eyes is among the thinnest on the body (approximately 0.5mm, compared to 2mm elsewhere on the face), making it particularly susceptible to volume loss, pigmentation changes, and vascular visibility.

According to a survey published in the Journal of Cosmetic Dermatology, under-eye concerns rank among the top three aesthetic complaints patients bring to dermatologists and plastic surgeons, alongside wrinkles and skin laxity. Yet the under-eye area is also one of the most nuanced to treat, because what looks like a single problem — “dark circles” or “bags” — can actually stem from multiple different causes, each requiring a different therapeutic approach.

This guide helps you identify the root cause of your under-eye concerns and understand which treatments offer the best evidence-based solutions.

Diagnosing Your Under-Eye Concern

The Four Primary Causes

Under-eye complaints generally fall into four categories, and many patients have a combination:

1. Tear Trough Hollowing (Volume Loss) The tear trough is the groove that runs from the inner corner of the eye diagonally toward the cheek. As midface fat pads deflate and descend with age, this groove deepens, creating a shadow that reads as a dark circle. According to research in Plastic and Reconstructive Surgery, tear trough deepening is primarily a volumetric problem — the shadow disappears when the hollow is filled. Understanding the science of skin aging clarifies why this volume loss accelerates in the midface over time.

How to identify it: The darkness follows the contour of the orbital rim. When you look upward or press gently on the cheek to push tissue up, the darkness improves.

2. Hyperpigmentation True pigmentation — melanin deposits in the under-eye skin — is particularly common in patients with darker skin tones. It may be genetic (periorbital melanosis) or acquired from chronic sun exposure, allergies, or eczema.

How to identify it: The darkness persists regardless of angle or lighting. It doesn’t improve with pressure or changes in head position. A Wood’s lamp examination at a dermatologist’s office can help differentiate.

3. Vascular Visibility The thin under-eye skin allows the underlying orbicularis oculi muscle and its blood vessels to show through, creating a blue, purple, or reddish discoloration. This is often genetic and can worsen with fatigue, dehydration, or allergies.

How to identify it: The color has a bluish or purplish tint. Gently stretching the skin may make the vessels more visible rather than less.

4. Under-Eye Bags (Fat Herniation) The fat pads that cushion the eyeball are held in place by the orbital septum. When this membrane weakens — due to aging, genetics, or both — fat pushes forward, creating puffy bags beneath the eyes. The National Institutes of Health (NIH) describes this as one of the hallmark signs of periorbital aging.

How to identify it: Puffiness that creates a convexity below the eye, often most pronounced in the morning or after salty meals. The bags cast a shadow into the tear trough, exacerbating the hollow appearance.

Non-Surgical Treatments

Tear Trough Filler

Tear trough filler is the most popular non-surgical treatment for under-eye hollowing. A small amount of HA filler — typically 0.3-0.8mL per side — is injected into the tear trough to fill the hollow, reduce shadowing, and create a smoother transition from the lower eyelid to the cheek.

Best products for tear troughs:

Technique matters enormously: The under-eye area is unforgiving. Overfilling creates a puffy, unnatural look. Too-superficial placement causes a bluish discoloration called the Tyndall effect. Most experienced injectors use a cannula (rather than a needle) for this area, as it reduces the risk of bruising and vascular complications.

According to a study in the Aesthetic Surgery Journal, patient satisfaction with tear trough filler averages 80-90% when performed by experienced injectors, but drops significantly with less experienced practitioners. Our guide to cosmetic treatment red flags can help you identify a qualified provider for this delicate area.

Cost: $600-$1,200 per session Downtime: Mild swelling and bruising for 3-10 days Duration: 9-18 months

Risks: Bruising (common), Tyndall effect (blue discoloration from superficial placement), lumpiness, vascular occlusion (rare but serious), malar edema (swelling of the cheek below the filler)

Platelet-Rich Plasma (PRP)

PRP therapy involves drawing the patient’s blood, centrifuging it to concentrate the platelet-rich layer, and injecting it beneath the under-eye skin. The growth factors in PRP stimulate collagen production and improve skin quality over time.

A randomized controlled trial published in the Journal of Cosmetic Dermatology found that PRP injections produced statistically significant improvement in periorbital dark circles compared to placebo, particularly in patients whose darkness was primarily vascular in origin.

Best for: Vascular dark circles, mild hollowing, overall skin quality improvement Sessions needed: 2-4, spaced 4-6 weeks apart Cost: $500-$1,000 per session Results timeline: Gradual improvement over 2-4 months

Polynucleotides and Skin Boosters

Polynucleotide injectables (such as Ameela or Plinest) and skin boosters (such as Profhilo or Skinvive) represent a growing category of treatments that improve under-eye skin quality without adding significant volume. These bio-remodeling products hydrate the skin from within, stimulate collagen and elastin, and improve the overall thickness and luminosity of the delicate periorbital tissue.

Cost: $400-$900 per session (typically 2-3 sessions needed) Best for: Crepey skin, mild darkening, skin quality improvement

Chemical Peels and Topical Treatments

For pigmentation-driven dark circles, topical treatments and light chemical peels can help:

• Vitamin C serums: Brighten and provide antioxidant protection
• Retinoids (low concentration): Thicken the dermis and improve texture — use with caution in the delicate periorbital area
• Kojic acid and arbutin: Gentle depigmenting agents
• Azelaic acid: Addresses both pigmentation and inflammation
• Caffeine: Temporary vasoconstriction that reduces puffiness and vascular darkness
• Light chemical peels (glycolic, lactic, or TCA): Can improve superficial pigmentation over a series of treatments

The American Academy of Dermatology notes that topical treatments are most effective for mild pigmentation and are best used as part of a broader treatment strategy. For deeper pigmentation concerns beyond the under-eye area, see our guide to hyperpigmentation solutions.

Laser and Light Treatments

Several laser and light-based treatments can address under-eye concerns:

• Fractional CO2 or erbium laser: Resurfaces and tightens the under-eye skin; improves crepiness and fine lines
• IPL (Intense Pulsed Light): Targets vascular discoloration and mild pigmentation
• Nd:YAG laser: Can target deeper vascular structures contributing to dark circles
• Morpheus8 (fractional RF microneedling): Tightens loose under-eye skin and stimulates collagen

A study in Dermatologic Surgery demonstrated that fractional laser treatment improved under-eye wrinkles and skin laxity by an average of 40-60% after a series of 2-3 sessions. Our comparison of chemical peels vs microneedling vs laser can help you understand which resurfacing technology suits your skin.

Cost: $500-$2,000 per session Best for: Crepey skin, fine lines, mild to moderate laxity, vascular discoloration

Surgical Treatments

Lower Blepharoplasty

Lower blepharoplasty (lower eyelid surgery) is the gold standard for under-eye bags caused by fat herniation. The procedure can be performed via two approaches:

Transconjunctival blepharoplasty: The incision is made on the inside of the lower eyelid, leaving no visible scar. Fat is repositioned or removed through this internal approach. This technique is ideal for patients with fat herniation but good skin quality.

Transcutaneous blepharoplasty: The incision is made just below the lash line. This approach allows the surgeon to remove or redistribute fat, tighten the orbicularis oculi muscle, and remove excess skin. It’s best for patients who need both fat and skin addressed.

According to the American Society of Plastic Surgeons, modern blepharoplasty increasingly favors fat repositioning (moving the herniated fat into the tear trough) over fat removal. This approach addresses both the bags and the hollowing in a single procedure.

Recovery: 1-2 weeks of significant swelling and bruising; most patients return to work at 7-10 days. Final results visible at 2-3 months. Cost: $3,000-$7,000 Duration: Results are long-lasting (10-15+ years), though aging continues

Fat Transfer to the Under-Eye Area

Autologous fat grafting can fill the tear trough with the patient’s own fat, harvested from another body area. While potentially longer-lasting than HA filler, fat transfer to the under-eye area carries a higher risk of lumpiness and overcorrection, and results can be less predictable.

Cost: $3,000-$6,000 Best for: Patients who want a more permanent solution to tear trough hollowing and are comfortable with a surgical procedure

Treatment Decision Matrix

What Not to Do

The under-eye area is high-risk territory. Common mistakes include:

• Overfilling the tear trough: More is not better. Excess filler creates puffiness, malar edema, and an unnatural appearance. Many revision patients have accumulated too much filler over multiple sessions.
• Using the wrong product: Thick, high-G-prime fillers are not appropriate for the thin under-eye skin. They can cause visible lumps and the Tyndall effect.
• Treating bags with filler: Filler cannot correct true fat herniation — it can only camouflage the adjacent hollow. Filling around bags may actually make them look more prominent.
• Ignoring the midface: Tear trough hollowing is often partly caused by midface volume loss. Treating the under-eye without restoring cheek volume may produce a suboptimal result.

The International Society of Aesthetic Plastic Surgery (ISAPS) emphasizes that under-eye treatments require specialized training and a conservative approach. Always seek a provider with specific experience in periorbital rejuvenation. Under-eye work is often most effective when incorporated into a broader full face rejuvenation plan that also addresses midface volume.

The Bottom Line

Under-eye concerns are among the most common — and most nuanced — aesthetic complaints. Effective treatment starts with an accurate diagnosis of the underlying cause, whether that’s volume loss, pigmentation, vascular visibility, fat herniation, or a combination. Non-surgical options like tear trough filler, PRP, and laser treatments can produce meaningful improvement for many patients, while lower blepharoplasty remains the definitive solution for true under-eye bags. Check our recovery timelines to plan downtime for whichever approach you choose. The best outcomes come from providers who evaluate the entire periorbital complex and develop a targeted, conservative treatment plan.

Frequently Asked Questions

Is tear trough filler safe?

Tear trough filler is generally safe when performed by an experienced injector using appropriate products and techniques. The main risks include bruising, swelling, the Tyndall effect (bluish discoloration), and in rare cases, vascular occlusion. Using a cannula rather than a needle, choosing a soft and low-hygroscopic filler, and maintaining a conservative volume all significantly reduce risk.

How long does under-eye filler last?

Under-eye filler typically lasts 9-18 months, depending on the product used, the amount injected, and individual metabolism. Some patients find that filler lasts longer in the under-eye area than in other parts of the face because this is a relatively low-movement area with limited metabolic activity.

Can dark circles be permanently treated?

The answer depends on the cause. Structural hollowing can be permanently addressed with surgical fat repositioning or blepharoplasty. Genetic pigmentation is difficult to eliminate permanently but can be significantly improved with ongoing topical treatment and periodic procedures. Vascular dark circles may respond to laser treatments but often require maintenance.

At what age should I consider blepharoplasty?

Most patients seek lower blepharoplasty in their 40s to 60s, though some with strong genetic predisposition to under-eye bags may benefit from surgery earlier. The procedure is appropriate when fat herniation creates visible bags that don’t respond to non-surgical treatment. A consultation with a board-certified oculoplastic or facial plastic surgeon can help determine timing.
