Hyperpigmentation and sun spots are darkened areas of the skin, usually caused by excess melanin from sun exposure, hormonal changes, or inflammation. They can appear on the face, hands, and body, often making the skin look uneven. These spots tend to become more prominent with age and continued exposure to UV rays. Although they are generally harmless, many people seek treatments to even out skin tone and achieve a more radiant complexion. Preventative measures, such as regular sunscreen use, can help reduce the development of new spots.
