Previous facial injectables are important medical information when a patient is considering a facelift, neck lift, blepharoplasty or facial fat grafting. Hyaluronic-acid fillers, collagen biostimulators, threads, permanent materials and energy-based treatments may change tissue planes, produce fibrosis or swelling, and make facial examination less predictable. A safe surgical plan begins with a complete treatment history and, when relevant, dermatologic ultrasound.

Why previous treatments matter before facial surgery

Facial surgery is planned according to anatomy: skin, fat compartments, ligaments, muscles, bone support and the relationship between the eyelid, cheek, jawline and neck. An injected or implanted material may add volume, migrate, trigger inflammation or remain in tissues longer than the patient expects. Threads and some energy treatments may create scarring that affects dissection.

This does not mean that every patient who has had injectables is unable to undergo surgery. It means that the surgeon needs to know what was done, where, when, how much was used and whether there were complications. The decision is individualized; it should not be based on a fixed waiting period or on the assumption that all previous products have disappeared.

Which procedures should be disclosed?

Patients should report all previous facial treatments, even when they were performed many years earlier or in another country:

• Hyaluronic-acid fillers and any previous hyaluronidase treatment
• Calcium hydroxylapatite, poly-L-lactic acid and other collagen biostimulators
• Permanent or semi-permanent fillers, including injectable silicone
• Threads or suspension sutures
• Facial fat grafting
• Radiofrequency, focused ultrasound, lasers and other energy-based procedures
• Previous facial, eyelid or neck surgery

Bring records whenever possible: product labels, dates, volumes, photographs and reports from the treating professional. If documentation is unavailable, describe the treated areas and any episodes of pain, redness, nodules, prolonged edema or infection.

What dermatologic ultrasound can show

High-frequency dermatologic ultrasound can help identify the location and pattern of some previously injected materials, fluid collections and areas of tissue change. It can be especially useful when the history is uncertain, the examination suggests residual product, or the patient has persistent swelling or nodules.

At Belvivere, ultrasound may be required before the final surgical plan is confirmed. It is one part of the assessment, not a guarantee that every substance or microscopic tissue change will be detected. Findings must be interpreted together with the clinical examination, medical history and proposed operation.

Hyaluronic acid and hyaluronidase

Hyaluronic-acid filler can sometimes be treated with hyaluronidase before surgery. However, response varies with the product, location, amount, age of the filler and tissue reaction. More than one session may be necessary, and complete removal cannot be guaranteed. Hyaluronidase also has its own risks and should only be used after medical assessment.

The surgeon may recommend treatment followed by a period of observation and a new examination before deciding when—or whether—to proceed. Surgery should not be scheduled on the assumption that a single hyaluronidase session has restored the original anatomy.

Biostimulators, threads and energy-based treatments

Collagen biostimulators are not dissolved with hyaluronidase. Their effects and associated fibrosis may persist. Threads may be difficult to locate and can affect dissection planes. Radiofrequency, focused ultrasound and other energy devices can also alter tissue quality, depending on the technology, depth and number of treatments.

These histories do not lead to one universal rule. In some cases, surgery remains appropriate with modified planning; in others, the safest choice is to postpone, limit the operation or avoid a specific plane. The surgical technique—including whether a Deep Plane approach is appropriate—must follow the patient’s anatomy and risk profile, not a marketing label.

Permanent fillers require special caution

Permanent materials present a different level of concern. Injectable silicone may spread through tissue, provoke chronic inflammation and cause severe complications. It cannot be managed like hyaluronic acid and is not dissolved by hyaluronidase. Depending on its location, extent and tissue response, elective facial surgery may be contraindicated or substantially limited.

Patients should never conceal permanent filler use out of concern that surgery will be refused. Accurate disclosure allows the team to protect the patient and explain realistic alternatives.

Can injectables replace surgery—or surgery replace injectables?

Neither statement is universally true. Injectables may be useful for selected volume deficits, expression lines or skin-quality goals, but they do not reliably correct significant tissue descent. Conversely, a facelift repositions deeper tissues but does not automatically restore every area of volume or treat all skin-quality concerns. Facial fat grafting, eyelid surgery or non-surgical treatment may be considered when indicated.

Risks and realistic expectations

Previous treatments may increase uncertainty, but they are only one part of surgical risk. Potential complications of facial surgery include bleeding, infection, fluid collection, delayed healing, scarring, asymmetry, contour irregularity, altered sensation, nerve injury, skin compromise, prolonged edema and the possibility of revision. Anesthesia and travel add separate considerations.

No imaging test, surgical plane or technology removes all risk. Dr. June Favarin’s planning prioritizes preservation of anatomy and facial identity, with the extent of surgery matched to the individual rather than routinely recommending the most extensive operation.

Planning from abroad

International patients can begin with a video consultation, standardized photographs and a detailed list of previous treatments. When ultrasound is required, the team will explain whether it should be obtained before travel or arranged in Brazil. A preliminary recommendation may change after in-person examination or imaging.

Patients traveling for facial surgery are generally advised to arrive in Criciúma one or two days before the procedure and remain for at least 15 days. Surgery is performed in an appropriate hospital setting, with postoperative reviews before the patient is cleared to fly. Belvivere’s concierge service assists with local logistics; clinical follow-up is provided by the medical team.

A safer consultation checklist

• Create a timeline of every facial procedure and product.
• Share photographs taken before and after previous treatments.
• Report persistent swelling, nodules, pain or inflammation.
• Do not arrange hyaluronidase or another procedure without medical guidance.
• Allow the surgical plan to change after examination and ultrasound.
• Plan enough time in Brazil for monitoring and medical clearance.

The objective is not to judge previous aesthetic choices. It is to understand the current anatomy, identify avoidable risks and recommend a plan that is medically responsible and consistent with the patient’s goals.
