What is hyperpigmentation characterized by?

Hyperpigmentation is characterized by the excess production of melanin in the skin, which results in the appearance of dark patches or spots. This condition can occur as a result of various factors, such as sun exposure, hormonal changes, medications, or skin injuries. The areas of hyperpigmentation are often more pronounced in individuals with darker skin tones, but it can affect anyone. The increased melanin accumulation causes the affected areas to become darker than the surrounding skin, signaling an abnormal response of the skin to certain stimuli. Understanding this characteristic is crucial for those in the esthetics field, as it guides treatment options and preventive measures for clients dealing with pigmentation issues.
