Cutometry – elasticity measurement

Measuring principle
The measurement of skin elasticity is based on the so-called suction method.
A negative pressure is produced in the measuring head, and the skin is drawn inside the instrument. An optical measuring system consisting of a light source and light receptor measures the light intensity, which varies in accordance with the degree of skin penetration.
The two parameters measured are firmness and elasticity. Firmness is measured in terms of the resistance that the skin displays against being drawn in by the negative pressure.
Elasticity is measured in terms of the time taken for the skin to return to its original state.
