Hyperpigmentation is a common skin condition where certain areas of the skin become darker than the surrounding skin, often appearing as dark spots or patches. This occurs due to an overproduction of melanin, the pigment responsible for skin color. It can show up as age spots, sun spots, melasma, or post-acne marks, and is often caused by sun exposure, hormonal changes, or skin injuries. While hyperpigmentation is not harmful, it can affect confidence and overall skin appearance.
