What condition is associated with increased pigmentation during pregnancy?

The condition associated with increased pigmentation during pregnancy is melasma. This skin condition is characterized by the development of dark, irregular patches primarily on the face, particularly on the cheeks, forehead, and above the upper lip. Melasma occurs due to hormonal changes during pregnancy, which can increase the production of melanin, the pigment responsible for skin color. The rise in hormones such as estrogen and progesterone triggers the melanocytes (the cells that produce melanin) to become hyperactive, leading to the characteristic pigmentation.

Understanding the nature of melasma is crucial, especially for those working in skin care or dermatology, as it typically resolves postpartum but can persist or recur with subsequent pregnancies or sun exposure. Recognizing melasma also distinguishes it from other skin conditions that may not show the same hormonal ties or pigmentation characteristics seen during pregnancy.
