Final answer:
Sun exposure hastens wrinkling, loosening, and spotting of the skin, making individuals look older.
Step-by-step explanation:
Sun exposure causes wrinkling, loosening, and spotting of the skin, making some individuals look older than their contemporaries. UV radiation from the sun damages collagen fibers, resulting in the acceleration of the aging process of the skin and the formation of wrinkles. Overexposure to the sun when young has been linked to melanoma later in life.
