Where should I get hyaluronic acid injection? Choose a clinic based on "preparedness for emergencies"

When choosing a clinic for hyaluronic acid injection, the shortcut is to check the clinic's readiness for complications before looking at reviews or product names. Serious complications are rare, but if a blood vessel becomes blocked, it can lead to skin necrosis or vision loss, and the outcome depends on whether the clinic can quickly recognize the problem and use the dissolving agent.[1].

How often do complications from hyaluronic acid injection occur?

Most are mild and temporary. In reports summarizing complications from hyaluronic acid, nearly all were mild and resolved naturally.[1].

On the other hand, the most serious complication is blood vessel blockage (vascular occlusion).[1]According to one report, abnormal blood flow can occur in up to 3 cases per 1,000 injections.[2]The most common eye complication, vision loss, occurs in 0.0008%, which is extremely rare.[3].

Why is a physician's knowledge of facial blood vessels important?

The risk of blood vessel blockage can be reduced by thorough knowledge of the facial blood vessel pathways.[1]Areas such as the space between the eyebrows, the temples, and the nose require special attention.[2][3].

Tool selection is also part of prevention. In high-risk areas, using a blunt-tip needle (cannula) is recommended.[4]Ask what precautions are being taken for each area where you want the injection.

How can I verify that the dissolving agent is readily available?

Hyaluronic acid can be broken down by an enzyme called hyaluronidase. It is used to treat nodules, overfilling, and blood vessel blockage.[5]Case reports state that the injecting clinic should have this agent readily available and staff should be trained in its use.[6].

The longer the response is delayed, the less effective the treatment becomes, and recovery takes longer.[4]In a case where the patient presented 3 days after injection, large amounts of the agent were used over several days for recovery, but delayed response is reported to become more difficult.[7].

There is currently no established guideline for treatment when blood flow to the eye is stopped.[8]Even in a report summarizing 144 cases, vision improvement varied.[8]That is why prevention and early response systems are crucial.

What does the quality of explanation tell you?

Whether the clinic explains serious risks before treatment is a good indicator of preparedness. According to expert recommendations, all important risks should be included in the informed consent form.[9].

The same recommendation advises clinicians to specifically communicate to patients dangerous warning signs such as eye pain or double vision. It is also important to instruct patients to report immediately if nodules appear.[9].

Checklist points for comparing clinics

There are four benchmarks to compare. The first is whether the clinic explains the blood vessel risks of the injection site.[1][2]The second is whether the dissolving agent is readily available and who decides when to use it.[5][6].

The third is whether the clinic educates you about dangerous warning signs.[9]The fourth is what to do and where to contact if any changes occur during the night or on days off after treatment.

What should I verify during my own consultation?

The risk level for the area where you want the injection and how much hyaluronic acid can change your appearance cannot be determined in this article. Tell the physician about the type and timing of any past injections, and confirm these details during your consultation.
