What does this guide say?
From the current commercial edition · PDF page numbers
- Explains why filler HA is crosslinked: native HA turns over within hours to about a day, so uncrosslinked HA would be gone within days.p. 4
- G′ measures firmness under shear, not lift; published G′ values differ between sources and should not be used to rank brands.pp. 5, 6
- Chooses filler by the role it must play — skin quality, dermal integrity, fat-emulating or skeletal-mimicking — defined by the tissue layer, not by brand name.pp. 7, 8
- A negative aspirate does not exclude intravascular placement; aspiration is never a standalone safeguard.pp. 9, 13, 22
- Weighs needle against cannula: population data favour the cannula for occlusion, cadaver and case-series data show cannulas can still penetrate arteries, and the needle keeps precision.pp. 14, 15
- Covers five regions — temple, tear trough, mid-face, lips and perioral, jawline and chin — with the vessel at risk, plane and instrument for each.pp. 20, 21
- Lays out a five-step vascular occlusion emergency protocol drawn from the CMAC/JCAD 2021 guidelines, with immediate escalation for any vision change.pp. 22, 23, 24

Who is this guide for?
Written for chairside use by trained injectors. Every dose, product and device specification must be confirmed against your own clinic protocol and the current instructions for use before treatment. Educational material. It does not replace regulatory labelling, local law, or clinical judgement in front of the patient. Original anatomical images retain their source markings. They are not patient-specific treatment maps. An editorial cover is not evidence of a treatment result.
