If we analyze above factors, it becomes clear that most often hyperpigmentation is a direct result of hormones disorder in the body, while excessive sun exposure is the catalyst for this process. That is, all pigmentation spots have one thing in common: they are sensitive to the sunlight. Therefore, hyperpigmentation: melasma (or chloasma) is most often seen in pregnant women and the elderly people. It should also be noted that a major role in the process of skin hyperpigmentation is played by an oxygen deprivation in body cells, leading to disruption in normal melanin synthesis, and, consequently, to the appearance of melasma or sun spots. In 95% of cases, hyperpigmentation spots appear on areas exposed to the sun, like the hands and face.
