The world of aesthetic medicine is awash with information—and misinformation. Among the most popular and discussed treatments are hyaluronic acid (HA) under eye fillers, designed to address hollows, dark circles, and the dreaded “tear trough” deformity. A quick scroll through social media reveals a paradoxical landscape: stunning transformations alongside horror stories of puffiness, migração, and unnatural results. This dichotomy often stems from pervasive myths that cloud public understanding. Separating evidence-based science from anecdotal fiction is crucial for anyone considering this nuanced procedure. This article dismantles the most common myths about under eye HA fillers, replacing sensationalism with science and provider expertise.
Mito 1: Under Eye Fillers Always Look Unnatural or “Inchado”
Perhaps the most enduring myth is that under eye fillers inevitably create a swollen, pillowy, or obvious “feito” aparência.
A realidade: A natural, refreshed result is absolutely achievable and is the standard for experienced, skilled injectors. The under-eye area is one of the most technically challenging facial zones to treat. It requires an in-depth knowledge of anatomy—including the delicate orbital septum, pre-periosteal fat pads, and intricate vascular network. The myth of puffiness often originates from several key failures:
- Enchimento excessivo: O “menos é mais” philosophy is paramount here. The goal is to restore lost volume subtly, not to over-inflate the area. A masterful injector places tiny, precise amounts of product in the deep supraperiosteal plane to lift and support from the bone upward, em vez de preencher superficialmente sob a pele fina.
- Escolha errada do produto: Nem todos os preenchimentos de ácido hialurônico são criados iguais. A área sob os olhos requer um produto específico: aquele que é altamente coeso, integra-se bem com o tecido, e tem um suave, consistência de gel fluido. Preenchimentos projetados para bochechas ou lábios costumam ser muito viscosos ou rígidos para a calha lacrimal, levando a caroços e efeito tyndall visível (uma tonalidade azulada).
- Técnica inadequada & Plano de Injeção: Como observou o Dr.. Lara Devgan, um cirurgião plástico líder certificado, “A calha lacrimal é um jogo milimétrico.” A injeção na derme superficial ou no plano fascial errado é a principal causa de inchaços visíveis, cumes, e descoloração.
Os dados falam: UM 2023 revisão no Revista de Cirurgia Estética concluiu que quando realizado por profissionais experientes usando cânulas apropriadas (instrumentos de ponta romba) e produtos modernos de HA, as taxas de satisfação do paciente com preenchimento ocular excedem 90%, com “aparência natural” sendo o resultado positivo mais citado.
Mito 2: Preenchimentos de ácido hialurônico são permanentes e arriscados de reverter
Um medo comum é que os resultados do preenchimento sejam permanentes, prender os pacientes em um resultado potencialmente indesejável.
A realidade: Os preenchimentos com ácido hialurônico são não permanente e reversível. Este é um dos seus maiores recursos de segurança. HA é uma molécula de açúcar que ocorre naturalmente em nossa pele. O AH injetável é reticulado para durar mais, mas ainda é biodegradável. Tipicamente, os preenchimentos de HA sob os olhos duram entre 9 para 15 meses, dependendo do produto, metabolismo, e fatores de estilo de vida.
Mais importante ainda, se houver um problema, como desigualdade, hipercorreção, ou uma complicação vascular – uma enzima chamada hialuronidase pode ser injetado para dissolver o enchimento de HA rápida e completamente. A hialuronidase é um “interruptor de segurança” que não existe com enchimentos permanentes ou semipermanentes. The myth of permanence may be confused with older silicone injections or the long-lasting nature of some biostimulatory fillers (como PLLA), which are not recommended for the delicate under-eye area.
Mito 3: Fillers Will “Migrate” ou “Travel” Far From the Injection Site
Viral images of filler allegedly migrating to distant parts of the face have fueled this alarming myth.
A realidade: True migration of a properly placed hyaluronic acid gel is exceedingly rare. Moderno, cohesive HA gels are designed to stay in place, forming a stable network that integrates with the tissue. What is often mislabeled as “migração” is typically one of two things:
- Poor Initial Placement: If filler is injected too superficially or in the wrong plane, gravity and muscle movement can cause it to shift slightly, creating a visible bulge or ridge close to the original site. This is a technique issue, not true long-distance migration.
- Filler Edema (Inchaço): As HA attracts and binds water (its primary function), some patients may experience mild, even swelling in adjacent areas, which can be mistaken for migration. This usually settles within a few weeks.
The use of blunt-tipped cannulas significantly reduces this risk, as they traverse tissue planes without damaging vessels and allow for more precise, fanning deposition along the bony contour of the orbit.
Mito 4: Under Eye Fillers Are the Best Solution for All Dark Circles
Many seek fillers as a cure-all for under-eye darkness, leading to disappointment when the issue isn’t fully resolved.
A realidade: Hyaluronic acid fillers are excellent for volume-related dark shadows. When the under-eye hollow deepens, it creates a topographic shadow, much like a valley casting a shade. By restoring volume, the shadow is eliminated, dramatically improving the appearance of darkness. Isso é conhecido como structural dark circle.
No entanto, dark circles can be multifactorial. Fillers will não significantly improve:
- Pigmentary Dark Circles: Caused by melanin deposition (common in deeper skin tones).
- Vascular Dark Circles: Caused by visible, thin-skinned capillaries (often bluish or purple).
- Thinning Skin: As skin ages and thins, the underlying orbicularis oculi muscle and vasculature become more visible.
A successful treatment plan requires a correct diagnosis. Muitas vezes, a combination approach—fillers for volume, plus maybe a laser for pigment or RF microneedling for skin quality—yields the optimal result.
Mito 5: The Procedure is Extremely Painful and Results in Massive Bruising
The fear of a painful, bruise-ridden recovery deters many potential patients.
A realidade: With proper protocol, the procedure is well-tolerated, and downtime is minimal.
- Gerenciamento da dor: Topical numbing cream is applied 20-30 minutos antes. Além disso, most premium HA fillers now contain integrated lidocaine (um anestésico local), which significantly comforts the injection process.
- Hematomas & Inchaço: While some minor bruising or swelling is possible (como acontece com qualquer injeção), its severity is drastically reduced by:
- Using cânulas instead of sharp needles, which slide between tissues rather than puncturing vessels.
- Pre-treatment avoidance of blood thinners (NSAIDs like ibuprofen, aspirina, certos suplementos como óleo de peixe, alho, ginkgo) para 7-10 dias.
- Post-treatment care including gentle icing and avoiding strenuous activity for 24-48 horas.
Most patients can return to social activities within 2-4 dias, with any minor bruises easily concealable with makeup.

Profissional Q&UM
P: I’ve heard that filler can cause blindness. Isso é verdade, and how high is the risk with under eye fillers?
UM: While the risk is extremely low (estimado em 0.001% por seringa), vascular occlusion leading to blindness is the most severe potential complication of any facial filler injection. The under-eye area has a critical vascular network. This is the single most important reason to choose a provider who is not just licensed, but extensively trained in facial anatomy and complication management. Expert injectors use techniques like cannulas, aspirar antes de injetar, and inject slowly with minimal pressure to mitigate this risk drastically. They also have hyaluronidase readily available for emergency reversal.
P: How do I choose the right provider for under eye fillers?
UM: Look beyond the price and the clinic’s decor. Your checklist should include:
- Credenciais: A board-certified dermatologist, cirurgião plástico, or oculoplastic surgeon is ideal. If a nurse injector or PA, ensure they work under direct, on-site supervision of such a doctor.
- Experiência & Specific Expertise: Perguntar specifically about their experience and number of procedures performed on the tear trough/under-eye area. Ask to see before-and-after photos of their actual patients.
- Consulta: A thorough provider will assess your facial anatomy, discuss the different causes of your under-eye concerns, manage your expectations, and explain risks in detail—not just sell you a syringe.
P: Can I use under eye filler if I have allergies or am prone to cold sores?
UM:
- Alergias: True allergic reactions to hyaluronic acid are exceedingly rare, as HA is biocompatible. No entanto, inform your provider of all allergies. If you have a history of severe allergic reactions (anaphylaxis), they may recommend a skin test.
- Cold Sores (Herpes Simplex): Injections can potentially trigger a viral outbreak if you are prone to cold sores. It is crucial to inform your provider. They will likely prescribe an antiviral medication (por exemplo, valacyclovir) to be taken before and after the procedure as a preventive measure.
P: How soon will I see the final result, and what is the maintenance like?
UM: Você verá uma melhora imediata, but the final result settles in about 2-4 semanas after any initial swelling subsides and the product fully integrates. Maintenance is not automatic “refilling.” As the product naturally metabolizes, you may choose a touch-up treatment typically after 12-18 meses to maintain the effect. The goal of a masterful injection is a gradual, natural-looking return to baseline, not a sudden “deflation.”
