I-8. Evaluation method

Skin phototype III-IV maintained in survival for an evaluation of changes in depigmentation or conversely skin phototype II for the evaluation of propigmentation

Histologcial evaluation of the number of melanic pigments in the melanocytes and the adjacent keratinocytes (coloration by Fontana-Masson)

Our experimental models

I. Cell cultures
II. Human skin kept alive
III. In vitro reconstitution of skin equivalents
IV. Scalp sample maintained in survival conditions
V. Clinical Evaluations
