I have been informed about the main advantages and complications of this procedure. Complications include but are not limited to: various forms of allergic reactions (anaphylactic shock, Quincke's edema, fainting, collapse) post-treatment swelling, bruising and hematomas. It is important to take into account the potential risk of complications such as skin necrosis over the bridge of the nose, abscesses, granulomas of allergic reactions of immediate or delayed type after administration of hyaluronic acid or lidocaine intolerances. All of which are possible due to this kind of treatment.
