Dr. MTAI
Your AI Instructor for Dermal Filler
Hello and welcome! Dermal fillers are both science and art, and I'm here to guide you through every aspect. From understanding hyaluronic acid properties to perfecting your injection technique, we'll cover it all. Ready to sculpt beautiful results?
Understand hyaluronic acid, rheology, and how different fillers behave in facial tissue.
Explore facial layers, vessels, and danger zones in interactive 3D models.
Practice filler placement in AI simulations. Get feedback on depth, volume, and technique.
Schedule live training when confident to work with real Juvederm® and Restylane®.
I'm Dr. MTAI, and I've designed these interactive learning tools to help you master the art and science of dermal filler injections. Understanding filler properties, facial anatomy, and injection techniques is essential for achieving beautiful, natural results. Take your time with each section — I'm here to ensure you feel confident before your hands-on practice.

Understanding the layered anatomy of the face is critical for safe filler placement. Unlike botulinum toxin which targets muscles, fillers are placed at various depths depending on the desired effect. I'll teach you to visualize facial layers, fat compartments, and danger zones.
Depth: 1-4 mm
Filler Use: Fine lines, superficial wrinkles (thin, low G' fillers)
Depth: Variable (4-15 mm)
Filler Use: Volume restoration, superficial fat compartments
Depth: Below subcutaneous fat
Filler Use: Structural support, lifting
Location: Below SMAS
Filler Use: Deep volume, structural support (high G' fillers)
Depth: Deepest layer
Filler Use: Supraperiosteal injection for structural support
Safety Alert
Vascular occlusion is the most serious complication of filler injection. Memorize these danger zones and always aspirate before injecting.
Vessel: Supratrochlear artery
Risk: Retrograde flow to ophthalmic artery → vision loss
Vessels: Dorsal nasal, lateral nasal, angular arteries
Risk: Nasal necrosis, vision loss via anastomoses
Vessels: Facial artery, angular artery
Risk: Inject superficially, aspirate, small aliquots
Vessels: Superficial temporal artery, deep temporal vessels
Risk: Deep injection risks vessel damage
Dr. MTAI's Tip
I always recommend injecting in the safest plane for each area. When in doubt, go more superficial — you can always add more filler, but you can't undo vascular occlusion.
Understanding filler rheology — the science of how fillers flow and behave — is essential for product selection. Each filler has unique properties that make it ideal for specific indications.
Key properties: G' (elasticity), cohesivity, particle size, and HA concentration.

Mastering multiple injection techniques allows you to achieve optimal results for different areas and indications. I'll teach you when to use each technique and how to execute them safely.
Method: Multiple small injections along a line
Best for: Lip border definition, fine lines
Volume: 0.01-0.05 mL per puncture
Method: Insert needle, inject while withdrawing
Best for: Nasolabial folds, marionette lines
Advantage: Even distribution along track
Method: Insert needle fully, inject while withdrawing
Best for: Deeper folds, structural support
Advantage: Better control of placement
Method: Single depot of filler at one point
Best for: Cheeks, chin, temples
Volume: 0.1-0.5 mL per bolus (max 0.1 mL in high-risk areas)
Method: Multiple passes from single entry point
Best for: Cheeks, temples, large areas
Advantage: Fewer entry points, less bruising
Method: Perpendicular passes creating grid pattern
Best for: Even volume distribution, large areas
Advantage: Smooth, natural result
Dr. MTAI's Tip
I prefer cannulas for high-risk areas like tear troughs and nasolabial folds. The blunt tip reduces vascular injury risk significantly.
Safety Alert
Always aspirate before injecting, especially in danger zones. If you see blood, withdraw and apply pressure. Use small aliquots (≤0.1 mL) and inject slowly.
Each facial area requires specific techniques, products, and injection planes. I've compiled my approach for the most common treatment areas to help you achieve consistent, natural results.
Products: Juvederm Ultra, Volbella, Restylane Kysse
Volume: 0.5-1.5 mL total
Technique: Serial puncture, linear threading
Plane: Vermilion border, body of lip
Products: Voluma, Restylane Lyft, RHA 4
Volume: 1-3 mL per side
Technique: Bolus (supraperiosteal), fanning
Plane: Deep (on bone) or submalar
Products: Restylane, Juvederm Ultra Plus
Volume: 0.5-1.5 mL per side
Technique: Linear threading, cannula
Plane: Deep dermis to subcutaneous
Products: Volbella, Restylane, Belotero
Volume: 0.3-0.5 mL per side (conservative!)
Technique: Cannula strongly preferred
Plane: Supraperiosteal (deep)
Products: Voluma, Restylane Lyft, Radiesse
Volume: 1-2 mL
Technique: Bolus, linear threading
Plane: Supraperiosteal
Products: Voluma, Volux, RHA 4
Volume: 1-2 mL per side
Technique: Linear threading, bolus
Plane: Supraperiosteal to subcutaneous
Dr. MTAI's Tip
I always approach the face holistically. Often, treating one area (like cheeks) reduces the need for filler in adjacent areas (like nasolabial folds). This creates more natural results with less product.
This is the most critical section of your training. Vascular occlusion is a medical emergency that requires immediate recognition and treatment. I require all my students to have hyaluronidase available and know exactly when and how to use it.
Signs: Immediate blanching, severe pain disproportionate to injection, dusky/mottled skin, slow capillary refill
Safety Alert
If you suspect retinal artery involvement (vision changes, eye pain), this is an EMERGENCY. Inject hyaluronidase immediately and arrange urgent ophthalmology consultation. Every minute counts.
Products: Hylenex, Vitrase (150 units/mL)
Ice, arnica, avoid blood thinners. Resolves 1-2 weeks.
Massage if early. Hyaluronidase if persistent. May need excision.
Blue discoloration from superficial placement. Hyaluronidase to dissolve.
Rare. Antibiotics, warm compresses. May need I&D if abscess.
Delayed nodules. Intralesional steroids, 5-FU, or excision.

AI Medical Instructor
Our AI breaks down the science of hyaluronic acid fillers in digestible modules. Learn how different products like Juvederm®, Restylane®, Belotero®, and Radiesse® each have unique properties for specific applications.
The AI helps you understand rheology (how fillers flow), G-prime (firmness), and cohesivity — enabling you to select the right product for each treatment area.
Practice virtually on every facial zone before touching a real patient:
Vascular occlusion is the most serious complication in filler injections. Our AI provides extensive training on facial vasculature, helping you identify and avoid danger zones.
Interactive 3D models let you explore arterial pathways and understand why certain injection techniques and depths are safer than others.
Our AI won't clear you for hands-on training until you've mastered complication recognition and management:
When the AI confirms your proficiency and YOU feel confident, schedule your in-person training to work with actual products on real patients.
