Elasticity/ Firmness

Skin elasticity / firmness
Is your skin's ability to stretch and then bounce back.
Loss of skin elasticity is known officially as elastosis – the degeneration of skin tissue due to ageing and other factors.

Measurement: face/ body
Kinetics: T0 and T+X weeks (4 weeks or 8 weeks)
Conclusion:
• Skin elasticity
• Skin firmness

Cutometer
This movement is determined by an optical system (composed of an infra-red diode, two prisms and a light sensor). The quantity of light detected by the sensor is proportional to the movement of the skin surface.

* Uf: maximum extensibility (final deformation) – in mm
* Ue: immediate extensibility (purely elastic component) – in mm
* Uv: visco-elastic extensibility (plasticity) – in mm
* Ur: immediate elastic recovery– in mm
* Ur/Ue: elastic deformation rate – no units
* Ur/Uf: elastic recovery rate – no units
* Uv/Ue: visco-elasticity rate – no units

Elasticity is defined as the quality of a skin or a material to change its shape under application of a certain force and to return to its original shape when the force is ceased to be applied. Therefore, the two ratios of both Ur/Ue and Ur/Uf are representative of skin elasticity improvement. Increases in these ratios are expected to conclude on a positive effect of the tested product(s) upon cutaneous elasticity.

Clinical evaluation by trained judge
- USE NON-STRUCTURED ANALOGICAL
- The evaluation is based on clinical examination of descriptor by trained judge. The descriptor (XX) assessed on the face
Suppleness Elasticity Firmness Tonicity

- An increase in the mark shows an improvement of the parameter except for the parameter xx where a decrease is expected to show an improvement.
