The skin attains its colour through a pigment that is known as melanin. The colour of a person’s skin is determined by the amount of melanin that is in the skin. Without the presence of melanin, the skin would be pale with various shades of pink due to the blood flow. For the most part, melanin is dispersed evenly throughout the skin.
Melanin is made up of series of cells called melanocytes combined with the cells that feature in the top layer of the skin, the epidermis. When the cells are damaged or in poor health, the production of melanin is affected. This causes the skin to expose itself as patchy. This patchiness can occur in certain areas or all over the body as a whole. Conditions such as age spots and freckles are a result of more melanin in specific areas.
If the body produces an excessive amount of melanin then the skin becomes darker in colour. If the body produces a small amount of melanin then the skin will appear lighter.
