The golden ratio mask is a mask using decagons and pentagons as a foundation for understanding how well a face conforms to the golden ratio. This mask was developed by Dr. Stephen Marquardt as a way of better understanding the similar qualities different cultures have found beautiful throughout the years.
In daily life, different expressions effectively change how an individual conforms to the golden ratio. This is seen most often when individuals smile, making the face closer to the golden ratio and more attractive to the human eye. The mask only measures the physical beauty of an individual face and not the less-tangible qualities of human attraction.
