What does chloasma refer to?

Chloasma, also known as melasma, refers specifically to brown patches that appear on the skin, typically on the face. These patches are a result of increased melanin production, often triggered by hormonal changes, sun exposure, or other factors. They are more commonly seen in women and can be associated with pregnancy, the use of birth control pills, or hormone replacement therapy. The term accurately describes the condition as it directly relates to the pigmentation changes that lead to the visible brown patches, making it distinct from other skin conditions like rashes or red spots that do not involve the same pigmentation change. Understanding chloasma is important in fields related to skincare and aesthetics, where it is crucial to differentiate between various skin conditions and their treatments.
