How to Inject a Vector

how to inject a vector

Each vector has to be applied ,, normal,, to the plan of each NFLs square or quadrant.

  • 1 Vector per Square
  • Applied to the center of each square
  • Normal or perpendicular to the plan of the Naso Labial Furrow Area.

Exactly as the pencil on the picture !

Quantity to Inject

.05 ml = 1/2 graduation of a 1 ml syringe
quantity to inject per vector

injection of the vector of the 1st quadrant

starting with the lowest quadrant of the naso-genial area
1 st lower square vector injection
  • Vectors  are all normal to the muscular plan, which means that the syringe makes an angle of 90 grades with the skin, exactly at the center of each ,, square,,.
  • Begin always to inject squares from down to up 
  • Your hand has always to be in contact with the patients skin or with the other hand .
  • Inject .05 ml per point
  • Use ultra flexible 30g1/2 needle

injection of the vector of the 2nd quadrant

2nd square vector injection
  • Always the position of the hand injecting is very important ,taking contact or a fixed position on the patients face.
  • Inject at each step .05 ml
  • Change of needle if it s curved or if the patients feels pain
  • The syringe as always for each vector has to be ,, normal,,to the center of the marked square ( point in the center of each square)

injection of the vector of the 3rd quadrant
