At what age does eighty percent of sun damage typically occur?

Eighty percent of sun damage typically occurs by the age of 18. This fact highlights the importance of sun protection during childhood and adolescence, as the skin is particularly vulnerable during these formative years. Exposure to ultraviolet (UV) rays from the sun can lead to cumulative damage over time, increasing the risk of skin cancer and premature aging later in life.

As children and teenagers often spend a significant amount of time outdoors without adequate sun protection, early education on the importance of sunscreen, protective clothing, and seeking shade becomes essential. Recognizing that the majority of sun damage can occur before adulthood emphasizes the need for lifelong protective habits to maintain skin health.
