Question: 1 / 400

What role do hormones play in the development of chloasma?

They lighten skin pigmentation

They cause increased melanin production

Hormones are crucial in the development of chloasma, often called melasma, which is characterized by dark, discolored patches on the skin, commonly seen on the face. Specifically, during pregnancy or with the use of hormonal contraceptives, the body's levels of estrogen and progesterone increase significantly. This hormonal change triggers melanocytes, the cells responsible for melanin production in the skin, to produce more melanin. This excess melanin leads to the hyperpigmentation associated with chloasma.

The essence of chloasma lies in its hormonal influences, particularly from estrogen and progesterone, which stimulate these melanocytes. Therefore, increased melanin production resulting from hormonal changes is foundational to understanding the condition's development, making this the accurate choice among the options.
