Background/purpose
The purpose of this clinical study was to identify dielectric markers to complete a previous thermal and vibrational study on the molecular and organizational changes in human dermis during intrinsic and extrinsic aging.
Methods
Sun‐exposed and non‐exposed skin biopsies were collected from 28 women devised in two groups (20‐30 and ≥60 years old). The dielectric relaxation modes...
Background and ObjectiveTo assess an objective method evaluating the effects of a retinaldehyde‐based cream (RA‐cream) on solar lentigines; 29 women randomly applied RA‐cream on lentigines of one hand and a control cream on the other, once daily for 3 months.
MethodsA specific method enabling a reliable visualisation of the lesions was proposed, using high‐magnification colour‐calibrated camera imaging...
