title: [How I explore ... the cheetah-look of the skin under selected light wavelengths].
abstract: The melanotic facial pigmentation of each individual is frequently heterogeneous, even when this condition remains imperceptible under natural ambient light. However, with aging, this aspect may appear to everybody. The melanin heterochromia has various origins including ethnicity, the hormonal impact, the influence of various inflammatory, toxic and drug-induced disorders, as well as the impact of photoaging. The cheetah-look aspect is thus established and well identified under ultraviolet light or using an ingenious trick selecting some wavelengths of visible light.
