The most important thing to note when conducting a FaceScan is to achieve even lighting across the face. Given that TOI needs to capture re-emitted light from blood flow, the face must be illuminated well and evenly.  

It is worth noting that a User with darker skin, may require more light across the face if having trouble conducting a successful scan.  

While it’s not a requirement, Users can also use ring lights to successfully illuminate their face. During FaceScan trial and validation studies, it was found that ring lights are the best method of achieving optimal illumination of the face.
