Skin colour variation with increasing age was analysed using a cross-sectional sample of 796 Basque boys aged from 8 to 19 years. Measurements were taken at the upper inner arm and forehead by means of an EEL DS29 Digital Unigalvo reflectance spectrophotometer with a nine-filter head. Ontogenic changes of skin pigmentation were found to be statistically significant. The influence of the month in which measurements were taken on reflectance values has been studied. Comparisons with another similar study (Pembrokeshire, Wales population) were carried out.
