Moles and chloasma are examples of what skin condition?

Moles and chloasma are categorized as hyperpigmentation conditions because they result from an excess production of melanin in certain areas of the skin. Hyperpigmentation occurs when there is an overactivity of melanocytes – the cells responsible for producing melanin – leading to darker patches or spots. Moles, which are typically benign growths, can appear anywhere on the body and vary in color while chloasma, also known as the "mask of pregnancy," manifests as brown patches usually found on the face. Understanding the nature of these skin conditions is essential, as it helps differentiate them from other skin issues such as hypopigmentation, which involves reduced melanin production, or skin cancer, which is characterized by the uncontrolled growth of abnormal skin cells.
