Tensor is quantity which depends upon 3 parameters : 1-magnitude 2-direction 3-plane
Vector depends only on 1-magnitude 2-direction
Endopeel Vectors are normal to the center of each chosen square
The syringe makes 90 grades with the skins butts square
Endopeel Tensors have 3 parameters
Position the syringe before pushing it and injecting the product
A tensor is when the syringe is positioned on the arrow of the chosen gluteal square PUSHING it with big force to fight against the Archimede force.( without changing the direction and the sense of the arrow).
The syringe has NEVER to do any angle with the superficia of the skin.The syringe has to be in full contact with the gluteal skin.
So there is a movement of shifting the tissues .
