Most skin diseases occur in people of all nationalities, regardless of their skin color. Certain problems encountered in the skin are more common in people with different hues of skin, and sometimes a disorder seems more prominent because it affects skin color.
Variations in skin color
Skin color is determined by cells called melanocytes. Melanocytes are specialized cells within the skin that produce a pigment known as melanin. Melanin is produced and stored within special structures, known as melanosomes, contained in the melanocytes. The melanocytes make up only a small percentage of overall skin cells. In fact, only two to three percent of all skin cells are melanocytes. The variation in skin color we see across all people is determined by the type and amount of melanin produced by the melanocytes.
Post-inflammatory hyperpigmentation and hypopigmentation
Melanocytes are very sensitive cells and can either stop producing color or produce excessive color in cases of inflammation. With the appropriate treatment, the color almost always returns to normal within a few weeks. In older patients, inflammation can lead to postinflammatory hyper-pigmentation. This is most commonly seen in areas where acne blemishes heal, leaving a dark spot behind. These too will fade with time; however, it can be quite persistent.
