What is the main cause of lentigo?

Genetic predisposition
Sun exposure
Hormonal changes
Allergic reactions

The correct answer is: Sun exposure

Lentigo, often referred to as liver spots or age spots, primarily results from sun exposure. These flat, brown spots appear on areas of the skin that have had significant exposure to ultraviolet (UV) light over the years. The UV rays from the sun stimulate melanocytes, the skin cells responsible for producing melanin, leading to localized hyperpigmentation. This condition becomes more prevalent with age, particularly in individuals who have spent considerable time outdoors without adequate sun protection. While genetic predisposition, hormonal changes, and allergic reactions can influence skin conditions, they are not the primary factors associated with the formation of lentigo. Genetic predisposition might play a role in how a person’s skin reacts to sun exposure, but the direct cause of lentigo is undeniably tied to cumulative UV exposure.
