Late-onset inflammatory reactions are rare complications that can occur after the injection of hyaluronic acid (HA) dermal fillers. Its cause may be of infectious origin or mediated by the immune system, and its outbreak can be triggered by a flu-like illness. Prevention is always better and easier than treatment, and after identifying the filler and the exact nature of the adverse side effect, the appropriate therapy is chosen. Early side effects, such as pain from the injection, immediate swelling, and edema, generally do not require specific treatment.
Cooling is sufficient to relieve immediate post-injection pain; however, this is rare after the addition of lidocaine as a local anesthetic. Swelling may respond to acetylsalicylic acid or another nonsteroidal anti-inflammatory drug. Placing too much material or in the wrong area requires immediate massage or extraction, if possible. The formation of lumps after the injection of calcium hydroxylapatite (CAH) into the lip is a technical failure, as well as an injection that is too shallow.
Proper training to inject this substance is mandatory. The most common side effects of Restylane include pain, swelling, redness, and swelling at the injection site. Usually, this occurs due to trauma from the needle being injected into the thin tissues of the face. These side effects should go away three to five days after the injection.
Restylane can also cause headache, nausea, and flu-like symptoms. Tell your doctor if these symptoms persist for more than five days. Inadvertent Injection into Blood Vessels is the most serious risk associated with dermal fillers. Filling that enters a blood vessel can cause skin necrosis (tissue death), stroke, or blindness. While the chances of this happening are low, if it occurs, the resulting complications can be serious and can be permanent. It's important to understand that dermal fillers are not without risks.
However, with proper training and knowledge of potential side effects and complications, these risks can be minimized. It's important to consult with a qualified healthcare professional before undergoing any type of dermal filler procedure.
