Self Tanning:
Skin colour is measured using a colorimeter. The L* (lightness) and b* (yellow chroma) values are measured in the CIELab space and are mathematically elaborated in order to calculate the Individual Typology Angle (ITA°). ITA° is related to skin colour. Instrumental evaluations may be associated with clinical/dermatological assessment
