To be safe and effective, the product selection and the various injecting techniques rely on a clear knowledge and understanding of facial anatomy and physiology.
Locating the complex, layered architecture and soft tissue compartments of the face is vital for accurate product placement while at the same time reducing the risks and complications associated with these medical procedures. Your injector should have a thorough knowledge of facial anatomy and physiology:
- Layers of the epidermis and dermis
- Subcutaneous tissue
- Natural fat pad compartments
- Retaining ligaments
- Bone plates / periosteum / prominences
- Foramen / notches
- Blood vessels - arteries, veins
- Lymph nodes
- Cultural diversity of face shapes and structures.
It is also important to understand the mechanisms involved – how each product works and the exact anatomical position where the product needs to be injected in order to deliver the best results.
There are many theories that guide universal proportions and facial aesthetics, including:
- Angles and eggs
- Koinophilia - the love of the average
- The 3 rings
- The angle of Liew
- The beauty triangle
- The golden ratio / phi (1:1.618)
- The rule of thirds and fifths
- The Marquardt beauty mask
- Ogee - S shaped curves.
The application of anatomy, product and aesthetic theories clearly demonstrates a professional respect for your safety and facial appearance.
