Structural and functional differences in skin of colour

The term 'skin of colour' (SOC), refers to individuals of African, Latinx, Asian, Native Hawaiian, Pacific Islander and Indigenous descent. These individuals typically have darker skin tones compared with white individuals and they often present with unique disorders of the skin or with common disorders that have a unique appearance. Certain skin conditions commonly associated with SOC patients, in contrast to individuals with lighter skin tones, are explained by structural and functional differences between this population and the white population. Variations in functional differences between these two groups are dependent on structural differences in melanosomes, stratum corneum, epidermis and dermis. Understanding the structural distinctions between white populations and SOC populations will provide insight into common disorders in SOC patients, including hyperpigmentation, hypopigmentation, dry skin, scaliness, xerosis, sensitive skin and keloids. Furthermore, understanding structural and functional skin difference will encourage more research regarding aetiology of disease and therapeutic interventions.
