Facial fillers are a popular choice for those looking to reduce wrinkles, fill in thin lips, or erase other signs of aging. However, it is important to be aware of the potential risks associated with the procedure. Accidental injections of facial filler into blood vessels can occur anywhere on the face, but are more likely to occur between the eyebrows and nose, in and around the nose, on the forehead and around the eyes. A sinus infection is a potential source of infection during dermal filler treatment, so it is important to postpone treatment until you are well.
Long-acting dermal fillers have higher rates of complications, such as infections and nodules. The FDA has warned that facial fillers can go wrong and tragically wrong. 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. It is important to note that temporary fillers can cause side effects at a frequency comparable to that induced by permanent and long-lasting fillers, but their duration is shorter and therefore less severe.
Injectors must have in-depth knowledge of facial anatomy and potential danger areas, especially the distribution of arteries and facial nerves. 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. Uncontrolled immune deficiencies may also be adversely affected by dermal filler injection or, conversely, may affect the behavior of the filler in the tissue. Volumetric rejuvenation of the face with fillers has gained popularity as the least invasive intervention.
Some side effects are transient, such as erythema and oedema, while some may persist, such as granulomas. Treatment of complications depends on several factors. 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. While many facial fillers provide immediate results, some will require several treatments over the course of weeks or months for optimal benefits, followed by occasional touch-ups.
