Structural lifting technique: fixed points and anchors
Lifting as a mechanical concept — supraperiosteal placement at fixed points, ligamentous anchoring, and why small volumes correctly sited outperform …
Articles
Clinical background for aesthetic practice: facial injection anatomy, the behaviour of hyaluronic acid fillers, botulinum toxin handling, and the complication patterns that shape safe technique.
These pages collect the reference material that sits behind injectable practice — where the vessels run, why a filler behaves the way it does in tissue, and what the recorded complication literature says about avoiding harm. They describe published knowledge; they are not treatment protocols.
Botulinum toxin pharmacology, units and handling
Serotypes, SNAP-25 cleavage, recovery by terminal sprouting, why units do not convert between brands, and the basis of secondary non-response.
High-dose pulsed hyaluronidase protocol explained
Why emergency reversal uses repeated high doses rather than a single injection, and what the published protocols and case reports actually describe.
Botox foundation handbook: the three licensed areas
A reference on glabellar complex, lateral canthal lines and frontalis treatment, covering mechanism, onset, duration and the diagnostic value of a …
How hyaluronidase breaks down hyaluronic acid filler
What the enzyme does to crosslinked gel, why product characteristics change how much is needed, and what it also does to the patient's own tissue.
Ischaemic stroke after facial filler injection
A rare but documented complication in which embolised material reaches the intracranial circulation — and why it is a transfer, not a clinic-managed …
Tear trough assessment before technique
Three different causes of the same infraorbital hollow, and why choosing the wrong one produces the results that make patients regret filler.
Cannula versus needle: vessel penetration risk
What the comparative data actually show about cannulas versus needles — a large reduction in reported occlusion, and the caveats that go with it.
Dilution of hyaluronidase: concentration and purpose
Why the reconstitution of hyaluronidase differs between elective dissolution and vascular emergency, and why no reliable …
Blindness after filler: visual loss and the 90-minute window
The reported distribution of cases, the mechanism, the sixty-to-ninety-minute window, and what the published guidance says to do.
Facial topography: reading the face in light and shadow
Reading the face as a surface of lights and shadows, and why that reading determines where volume should go.
Filler rheology made simple: G prime and cohesivity
G prime, viscosity and cohesivity explained in terms of what they actually predict about how a gel behaves once it is in tissue.
