A standardization of the skin typologies based only on visual criteria therefore appears difficult and would require in the more or less long term to resort to other quantitative means of identification, notably referring to biochemical and biophysical data.
After a quick reminder of the parameters on which the traditional classifications are based, an overview of the incidence of race, age, sex, and anatomical site on the measurement of the various skin biophysical characteristics will be proposed to show the limits of any kind of classification.
