A sinus infection is a potential source of infection during dermal filler treatment, so try to postpone treatment until you are well. Accidental injections of facial filler into blood vessels can occur anywhere on the face. But an FDA analysis of studies and reported problems found that it was more likely to occur between the eyebrows and nose, in and around the nose, on the forehead and around the eyes, the agency said. According to research published in Aesthetics, long-acting dermal fillers have higher rates of complications, such as infections and nodules.
Dermal fillers can cause HSV reactivation. Most relapses of HSV occur in the nasal mucosa, the perioral area, and the mucosa of the hard palate. In a patient with a history of cold sores, 1 gram of valacyclovir should be given the day before and continued for three days after the injection, as well as if an episode of HSV occurs after the injection. In patients with active herpes lesions, HA fillers should be delayed until complete resolution.
While many facial fillers provide immediate results, according to the American Academy of Dermatology (AAD), some of them will require several treatments over the course of weeks or months for optimal benefits, followed by occasional touch-ups. The FDA has told manufacturers of facial fillers to update their labeling to include additional warnings about the risk of accidental injection into blood vessels. Injecting facial fillers into blood vessels can cause blockages that restrict blood supply to tissues. However, a small pilot study compared hyaluronic acid-based filler injection immediately followed by laser, radiofrequency (RF) or pulsed light (IPL) treatments with filler injection alone.
There is a misconception that temporary fillers rarely cause side effects; the frequency is comparable to that induced by permanent and long-lasting fillers, but their duration is shorter and therefore less severe. The wide range of dermal fillers available for use in facial aesthetics makes it essential to have a thorough understanding of the relevant product characteristics. Uncontrolled immune deficiencies, such as graft-versus-host disease, chronic urticaria, and Quincke's edema, may also be adversely affected by dermal filler injection or, conversely, may affect the behavior of the filler in the tissue. Physicians should also fully inform patients about the risks associated with the procedure, know the signs and symptoms of accidental injection of facial filler into blood vessels, and have a plan to treat patients if this occurs.
