Uneven skin tone, characterised by patches of skin that appear darker or lighter than the surrounding area, can stem from various factors such as sun exposure, hormonal changes, or even skin injuries. Hyperpigmentation, another common concern, manifests as darkened patches on the skin due to excess melanin production. Sunspots, often referred to as age spots or liver spots, are darkened areas caused by prolonged exposure to the sun's harmful UV rays.
