ABSTRACT
The rst contact we have with someone else is usually when we look at his/her face. And through this rst glance, the impressions we have about that person remain engraved in us for a long time.
The face plays a fundamental role in human interactions. People’s faces tell us about their identity and origins. They also help us judge their age, condition of health, and even what mood they might be in. Many studies have focused on the importance of face shape in the evaluation of age, attractiveness, or health [1,2]. But more recently, numerous works have highlighted how skin color contributes to the way in which we perceive these important elements in our social interactions [3-8]. The visible appearance of human skin has also long been used as a major assessment tool in the clinical evaluation of physiological and pathological phenomena [9-13].
