Are there side effects associated with injecting hyaluronic acid for wrinkle reduction?

Injecting hyaluronic acid for wrinkle reduction may have side effects. These may include redness, swelling, pain, and itching at the injection site, as well as skin irregularities caused by uneven injections. In severe cases, if blood vessels are damaged during injection, vascular embolism may occur, which could be life-threatening. Allergic reactions may also occur in individuals who are sensitive to hyaluronic acid. Therefore, it is important to choose a qualified hospital and physician for the procedure and to follow post-treatment care instructions.
