What are solar lentigens a form of?

Solar lentigines, commonly known as sunspots or liver spots, are a form of hyperpigmentation. These skin lesions develop due to prolonged exposure to ultraviolet (UV) light from the sun, which stimulates the production of melanin in the skin. Unlike hypopigmentation, where the skin has less pigment or lighter patches, hyperpigmentation results in darker spots or areas on the skin, as seen with solar lentigines.

The formation of solar lentigines is a natural response to UV damage, representing an increase in melanin production as a protective mechanism for the skin. Understanding this condition is crucial for both cosmetic and dermatological considerations, particularly in terms of preventing further sun damage and addressing aesthetic concerns.
