Experimental proof
In order to prove the presence of the golden section in the structure of human faces, measurements were taken for certain node points on several hundred faces. Photos were used to take measurements. Faces were turned precisely towards the viewer, the emotional condition of people in the photos was neutral, there were no external attributes (for example, hats). The faces were measured and analyzed with software specifically designed for the purpose.

The following geometric proportions were selected:
·Distance between eyes/Nose width;  
·Head height/Face height  
·Face height/(Face height - Chin height)  
·(Face height - Chin height)/Mouth width  
·Face width in the mouth area/Nose length  
·Head height/Face width within the eye area  
·Face width in the eye area/(Face height - Chin height)  
·Face height/Forehead height
