Avoiding the Danger Zones: A Beginner's Guide to Facial Anatomy for Injectors
Why do even experienced injectors sometimes make critical errors? Often, it comes down to one thing: misjudging the danger zones. The human face is rich with vessels, nerves, and delicate structures. In the wrong hands - or even just with the wrong angle - an aesthetic injection meant to enhance can result in complications like vascular occlusion, nerve injury, or even blindness. That's not fear-mongering - it's medical fact. A 2020 review published in Dermatologic Surgery reported that the glabella, nasolabial fold, and infraorbital region were the most common areas for filler-induced vascular accidents. The key takeaway? Understanding facial anatomy isn't optional - it's non-negotiable. What Are Facial Danger Zones? These are anatomical regions where important arteries and nerves run close to the surface - or have few protective tissues - making them more prone to injury during injection. Some of the most critical zones include: Glabella (between the brows): w...
