Key takeaways
- Different problems, different tools.
• HA tear trough filler restores volume when placed deep in tiny amounts by an expert; watch for swelling, Tyndall effect under eye filler, and the (very rare) risk of vascular events.
• PRF under eyes is autologous; think skin-quality and crepiness support, not big volumisation. Usually done as a series.
• Lasers (CO₂ / Pico) smooth texture and address pigment; they don’t “fill” hollows. - Diagnosis first. True fat herniation or eyelid laxity may need surgical input; safe non-surgical blepharoplasty Toronto plans begin with accurate assessment.
What Causes “Tear Troughs” (Under-Eye Hollows)?
The under-eye is a convergence zone. Ligaments tether, midface fat pads deflate or descend, the skin thins, and suddenly you see a hollow or a shadow that wasn’t there before. Sometimes the “dark circle” is pigment. Sometimes it’s shadowing from volume loss. And sometimes that bulge is lower-eyelid fat creating a pseudo-hollow just beneath it.
Why does this matter? Because tear trough treatment Toronto isn’t one thing. If the problem is volume loss, we think about structure and support. If the skin is crepey, we think of stimulation (PRF, lasers). If pigment dominates, we treat pigment. Modern classifications help us map it out; your plan should reflect the actual driver, not a one-size fix.
Treatment Options — How They Work & What They’re Best For
Hyaluronic Acid (HA) Tear-Trough Filler
How it works. Adds back selective volume to reduce a hollow. Typically deep placement, micro-aliquots, often with a cannula to reduce bruising. Low-hygroscopic products are preferred to limit water draw and puffiness.
Best for. Structural hollows with decent skin quality. Often, we start with midface support first; sometimes a small lift there softens the trough enough that less (or no) direct under-eye filler is needed.
Safety profile. Expect transient swelling or bruising. Too-superficial placement can cause a bluish hue — the Tyndall effect under eye filler. The periocular area also carries a rare vascular occlusion/vision risk, which is why you want an experienced injector with reversal enzyme (hyaluronidase) and clear protocols. Ultrasound guidance is increasingly used in high-risk zones.
Longevity & sessions. Months, variable by product and metabolism. Touch-ups stay conservative.
“Under eyes are delicate and require care. We assess anatomy first, use the smallest effective dose, and protect the eye meticulously when lasers are involved. Safety is the plan, not an add-on.”
— Sharon R. Cassar, RN, MSN, FNP (C)
PRF (Platelet-Rich Fibrin)
How it works. Your own platelets and growth factors in a fibrin matrix → gradual collagen and extracellular matrix support. Think slow-build improvements in texture and elasticity rather than a filler-like “pop.”
Best for. PRF under eyes shines with crepiness, mild dark circles with a skin-quality component, and for patients who prefer “own-tissue” options. We often pair PRF vs filler under eyes by starting with PRF for the canvas, then adding a tiny HA dose only if a residual hollow remains.
Evidence note. Growing, promising — still more limited than HA for pure volume. Set expectations accordingly.
Safety profile. Generally well-tolerated; brief swelling/bruising possible. Minimal volumization.
Laser (Fractional CO₂; Pico/Nordlys for pigment)
How it works. CO2 laser under eyes (fractional CO₂) resurfaces and thickens the dermis to soften fine lines and crepiness. PicoWay/Nordlys toning addresses pigment and dyschromia. None of these fill a trough, but they make the skin better above it.
Ocular safety. Around eyes, metal corneal shields and periocular laser protocols are non-negotiable. This is trained-provider territory.
Downtime. Pico and similar toning = social downtime. Fractional CO₂ = a few days of visible healing (plan time off if you need it). Great for laser under eye wrinkles when skin quality is the issue.
Comparison Table — Results, Safety & Fit
| Feature | HA Filler | PRF | Laser (CO₂ / Pico) |
|---|---|---|---|
| Primary effect | Volume replacement | Skin-quality / crepiness | Texture/fine lines; pigment |
| Onset | Immediate; settles ~2 weeks | Gradual (weeks) | Days–weeks as skin heals |
| Sessions | 1 + conservative touch-ups | Series (e.g., 2–4) | Series; device-dependent |
| Longevity | Months (varies) | Emerging data | Months+ with maintenance |
| Key risks | Swelling, Tyndall; rare VO | Swelling/bruising | PIH if mis-selected; downtime; strict eye shielding |
| Reversible? | Yes (hyaluronidase) | N/A (autologous) | N/A |
VO = vascular occlusion.
Who Is the Safest Candidate for Each? (Decision Notes)
- Mostly hollowing + good skin: start with tear trough filler conservatively (often after midface support).
- Crepey skin/fine lines or pigment: consider CO₂ for texture and Pico/Nordlys for pigment/redness — with strict ocular protection.
- Edema-prone, lymphatic issues, or filler-averse: begin with PRF under eyes to nudge skin quality; reassess later for minimal HA.
- Prominent fat herniation or eyelid laxity: discuss oculoplastic options; don’t chase it with filler volume. Overfilling looks worse — and feels worse.
Risks & Red Flags (What to Watch For)
Filler. Escalating pain or pressure, blanching/mottling, cool skin, visual symptoms → urgent protocol. Call the clinic immediately. Mild, even puffiness? Often expected early on; the team will advise.
Laser. Proper shields. Trained operator. Conservative parameters for darker skin tones. If you see light sensitivity or unexpected pain — stop and speak up.
Recovery & Aftercare (Quick Guide)
HA filler: cool compresses, sleep slightly elevated, skip pressure and massage unless instructed. Watch for the signs listed above.
PRF: minimal downtime; gentle skincare; results accumulate over weeks.
Laser: follow the CO₂ protocol — cleanse as directed, occlusive healing ointment, strict sun protection, patience while fresh collagen forms.
Tear-Trough Care at Philosophy of Beauty
There’s no single “right” answer — there’s your answer. We evaluate ligament support, midface volume, skin thickness, pigment, lymphatics, and your tolerance for downtime. Then we build a dual-modality (sometimes tri-modality) plan:
- Conservative Dermal Fillers (Toronto) when true hollowing is present.
- PRP / PRF Treatment (plus our deep-dive on the science) and collagen-banking over a series.
- CO2RE Skin Resurfacing for texture/crepiness;
- Eye & Lip Rejuvenation (our non-surgical lift approach);
- PicoWay Laser Toning and Nordlys™ for pigment and redness control.
Prefer an under eye filler Toronto appointment first, then optimize the results? Or a skin-first plan with under eye PRF Toronto and later micro-dosing filler? We’ll map it with you.
FAQs
Is under eye filler safe?
In expert hands, yes. The area is delicate, so dosing stays low, placement stays deep, and reversal enzyme is on-site. We explain signs of vascular occlusion so you know when to call — rare, but important.
Can PRF replace filler for hollows?
PRF is excellent for skin quality and crepiness; it does not replace filler when the issue is volume loss. Many patients do both — PRF series first, filler later.
Laser vs filler for dark circles?
If pigment and texture dominate, laser under eye wrinkles (CO₂) and toning win. If shadow from a hollow is the culprit, filler wins. Often, it’s a blend.
How fast will I see results?
Filler is immediate but settles over ~2 weeks. PRF builds gradually across sessions. CO₂ shows improvement as you heal and remodel collagen over weeks.
Do you treat all skin types safely?
Yes — device choice and parameters change by skin tone, and we use intraocular eye shields to protect the eyes.
Ready for a plan that fits your eyes (and your life)?
