The Jawline & Lower-Face Atlas

Angle, chin & contour — from marking to aftercare.

Same jaw. Two instruments. Two rules.

A reference-grade guide to mandibular contouring — marking, plane, instrument and dose — for aesthetic physicians and injectors.

58 pages, one region — mapped from the danger zones to the touch-up
The cannula methodandthe needle method, side by side
Male vs female protocols — angle, dose, density, masseter

Built like a decision system

Not organised like a textbook

Every page answers one question in the order you actually face it at the chair — so you decide, then inject.

Mark the danger
Palpate the facial artery at the masseter, find the parotid, map the mental foramen — then mark the jaw.

Choose the plane
Plane is the safety decision, not decoration. Subcutaneous for the edge; on-bone for the sharpest angle.

Pick the instrument
Blunt cannula for safe volumising along the edge; sharp needle for defined, on-bone angle and chin.

Deposit & recover
Aspirate every stick, deposit slowly, then follow a two-week aftercare and symmetry check.

Inside the atlas
Ad-clear at a glance. Clinic-precise on the page.

Fig. 17 • Part 1
The lower-face danger-zone master map
Four structures govern every lower-face injection: the facial artery, the artery at the masseter crossing, the parotid, and the mental artery. One map, colour-coded, before any product moves.

Fig. 8 • Part 1
The facial artery at the masseter
A palpable muscle locates an unseen vessel. Ask the patient to clench, feel where the artery rounds the anterior border of the masseter, and work with a cannula from a point away from it.

Part 2 • Cannula technique
The cannula method, step by step
Cut up, aligned to the scale, air removed. One shallow puncture sets the path; the angle bolus anchors the corner; a linear-retrograde pass builds the posterior wall of the mandibular angle.

The aspiration test — the rule that closes every stick
Stabilise, pull and hold pressure 15–30 seconds, observe the hub, decide. No deposit without a preceding aspiration test — on every point, every time.

Part 4 • Male vs female
The male jaw asks for roughly twice
Angle comparison, chin comparison, skin and tissue differences — quantified. Denser tissue and 20% more collagen are why the dose rises and the angle build changes for men.
