Melasma is a chronic skin condition that causes brown or gray-brown patches, often appearing on the face, including the cheeks, forehead, nose, and upper lip. It is commonly triggered by hormonal changes, sun exposure, or genetic predisposition.
Sun/age spots, also known as solar lentigines, are flat, pigmented areas that develop on sun-exposed skin over time. These spots are more common with aging and result from prolonged ultraviolet (UV) exposure.
