1. A method for characterizing the state of an epithelium comprising at least steps consisting in:
a) determining in a sample of the epithelium a content of a polypeptide having the amino acid sequence of SEQ ID NO:2, and b) comparing the content determined in step a) to a reference value which is the content of the polypeptide obtained from an epithelium sample of a normal skin, the state of the epithelium being ageing, the state being characterized by a decrease between the reference value and the content determined in step a).
