Brief summary
This study aims to evaluate skin aging of an homogeneous population of 77 years old patient selected among the PROOF cohort who has been continuously investigated by cardiological examination. Skin aging will be explored by macroscopic and microscopic evaluation. In particular, skin aging will be measured by an index of clinical aging (SCINEXA) and other complementary measures such as facial photos, standard and High Definition dermoscopy, elastography, sebumetry, in vivo and ex vivo confocal microscopy, and classical histological examinations.
Interventions
Clinical pictures, Dermatoscopy, Elastography, Sebumetry
Skin biopsy for examinations by confocal microscopy ex vivo and histopathology
Examination by confocal microscopy in vivo

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| SCINEXA score | Day 1 | The aging of the skin is evaluated by a semi-quantitative composite of 19 clinical variables : the score SCINEXA |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| in vivo confocal microscopy | Day 1 | Skin aging evaluated by in vivo confocal microscopy |
| ex vivo confocal microscopy | Day 1 | Skin aging evaluated by ex vivo confocal microscopy ( thickness of the epidermis with and without the stratum corneum, dermis thickness , number of sweat glands per unit volume). |
| histology | Day 1 | Skin aging evaluated by conventional histology (thickness of the epidermis and dermis, presence and degree of elastosis , flattening of the dermo- epidermal junction) |
| RAMAN | Day 1 | The composition of subcutaneous fat measured by ex vivo RAMAN spectroscopy |
