What is the correct term for increased pigmentation in the skin?

Hyperpigmentation is the correct term for increased pigmentation in the skin. This condition occurs when an excess of melanin, the pigment responsible for skin color, is produced in certain areas. It can manifest as dark patches or spots and is commonly triggered by factors such as sun exposure, hormonal changes, certain medications, or skin injuries.

Understanding hyperpigmentation is crucial in medical aesthetics, as it has implications for treatments aimed at evening skin tone or reducing the appearance of dark spots. Recognizing the causes and types of hyperpigmentation can also guide practitioners in providing effective skincare solutions and treatments.

The other terms refer to different skin conditions: hyperkeratosis involves thickening of the outer layer of the skin; hypopigmentation signifies a reduction in skin pigment; and dermatosis is a general term for any disease of the skin. These distinctions highlight the specificity necessary when discussing dermatological conditions.
