Non-surgical facial rejuvenation techniques are increasing and are now undertaken by plastic, maxillofacial and ENT surgeons as well as non-surgeon technicians in the private sector. Although the technique of using fillers is less invasive than surgical options, it is not without risks, complications and the potential for poor cosmetic outcomes. This article goes through some of the general principles of facial fillers but then focuses on six potential danger areas and goes into detail about anatomy and potential complications. The overall anatomy of the brow and glabellar region, temporal region, infraorbital area, lips/commissure, nasolabial fold and the nose are all detailed and in addition a cadaveric dissection was undertaken with labelled pictures shown to highlight the anatomy being discussed. Although this article is solely an anatomy review with expert advice, it is an excellent overview of facial vascular anatomy and will be extremely useful for trainees with an interest in facial plastic surgery.
