Primary Causes of Actinic Keratosis
Actinic keratosis is primarily caused by long-term exposure to ultraviolet (UV) radiation from the sun or tanning beds, which damages the skin’s DNA over time. Individuals with fair skin, a history of frequent sunburns, or who spend significant time outdoors are at higher risk. The cumulative effect of UV exposure leads to abnormal cell growth, resulting in the rough, scaly patches characteristic of this condition.
