SKIN-FOCUSED TECHNOLOGY
For the first time in France, FIRN allows you to measure your skin’s cellular longevity, going beyond traditional skin type assessments.
Using high-tech probes developed from clinical testing laboratories, discover real, precise measurements of your skin.
Collagen levels and their visual distribution in the skin are measured using an ultrasound probe. See how UC affects your dermis.
Hydration is measured in two areas of the face: the T-zone and the cheeks. These areas often have specific hydration needs.
The elasticity probe measures your skin’s ability to return to its original shape after being stretched.
