Evaluating relaxing effect of fragrance


You can visually measure stress and relaxation. It is more objective and reproducible, compared to typical medical interview-based self-assessment. 

Combining the relaxation assessment and skin measurement, we can evaluate the improvement effect of the skin's condition due to mental stress. 


Test items

Pupillary reflex measurement

We measure the pupil size contraction(miotic pupil rate) before and after evaluation. 

When relaxed, miotic pupil rate increases.

Peripheral skin temperature measurement (Fingertips)

We monitor and quantify changes in blood flow at the fingertips before and after evaluation.

When relaxed, blood flow at the fingertips increases.
