Most side effects are mild or moderate in nature, and their duration is short lasting (2 days or less). The most common side effects include, but are not limited to, temporary injections site reactions such as redness, pain/tenderness, firmness, swelling, lumps/bumps, bruising, itching, and discoloration. As with all skin injection procedures, there is a risk of infection or ischemia. Complications such as skin necrosis or blindness, while present, are exceptionally rare.
