Hyaluronic Acid Filler Fundamentals

Apply facial anatomy knowledge and product-specific properties to plan safer, more precise hyaluronic acid filler injections.

What this track covers

This track covers the properties of hyaluronic acid fillers, the facial layers and vascular structures relevant to injection safety, and the clinical reasoning behind product and technique selection. It's built for clinicians who inject or plan to inject fillers and want a structured way to reinforce anatomy, product knowledge, and complication recognition.

What you will practice

  • Identifying facial danger zones and vascular danger areas before selecting an injection site
  • Comparing filler rheology properties (G prime, cohesivity, viscosity) to match product to treatment goal
  • Recognizing early signs of vascular occlusion and outlining an escalation pathway
  • Selecting injection depth and technique based on facial layer anatomy
  • Talking through informed consent points for expected effects and possible complications

Simulator scenario

A virtual patient presents shortly after tear trough filler injection with worsening pain and skin blanching, prompting the clinician to recognize and respond to a possible vascular event.

Board question topics

  • Facial vascular anatomy and danger zones
  • HA filler rheology and product selection
  • Recognition and management of filler complications
  • Injection depth and technique by facial region
