FAC FAC Injectable Treatments & Protocols 2 — Questions and Answers
Question 1: Which facial region is most commonly treated with botulinum toxin for dynamic wrinkle reduction?
- Cheeks and midface
- Upper face: forehead, glabella, and crow's feet (Correct answer)
- Nasolabial folds
- Chin and jowls
Correct answer: Upper face: forehead, glabella, and crow's feet
The upper face — including the forehead lines, glabellar complex, and periorbital crow's feet — is the primary target for neuromodulator injections.
Question 2: In lip augmentation using dermal fillers, what is the recommended approach to achieve natural results?
- Inject a large bolus into the center of the upper lip
- Use small aliquots with a cannula or needle following the lip anatomy (Correct answer)
- Inject deeply into the orbicularis oris muscle
- Fill the entire perioral area in one session
Correct answer: Use small aliquots with a cannula or needle following the lip anatomy
Natural lip augmentation requires precise, small-volume injections along the vermilion border, Cupid's bow, and body of the lip.
Question 3: What is the primary purpose of using a cannula instead of a needle for filler injections?
- Cannulas allow faster injections
- Cannulas reduce the risk of vascular injury and bruising (Correct answer)
- Cannulas provide more precise product placement
- Cannulas are required by FDA guidelines
Correct answer: Cannulas reduce the risk of vascular injury and bruising
The blunt tip of a cannula minimizes vessel penetration and bruising risk compared to a sharp needle.
Question 4: A patient reports sudden visual changes immediately after a filler injection. The practitioner's FIRST action should be:
- Apply ice and monitor for 15 minutes
- Stop the injection and administer hyaluronidase urgently (Correct answer)
- Massage the area vigorously
- Reassure the patient and complete the treatment
Correct answer: Stop the injection and administer hyaluronidase urgently
Sudden visual disturbance after filler injection may indicate retinal artery occlusion; immediate cessation and hyaluronidase administration are critical.
Question 5: Which filler product characteristic is most important when selecting a filler for deep structural volumization of the cheeks?
- Low G-prime (soft and spreadable)
- High G-prime (firm with high lifting capacity) (Correct answer)
- Low viscosity for easy injection
- Rapid degradation for short-term results
Correct answer: High G-prime (firm with high lifting capacity)
High G-prime fillers have greater elastic modulus, making them ideal for structural lift and deep tissue volumization.
Question 6: Biostimulatory injectables like poly-L-lactic acid (PLLA) work differently from HA fillers because they:
- Provide immediate volume through physical displacement
- Stimulate the body's own collagen production over time (Correct answer)
- Block nerve signals to reduce muscle movement
- Are permanent and cannot be dissolved
Correct answer: Stimulate the body's own collagen production over time
PLLA is a collagen stimulator that triggers fibroblast activity to gradually produce new collagen, with results developing over 3–6 months.
