The more sun you’ve been in over your whole life, the more wrinkles you’ll likely have on your face as you get older—and guys tend to have more wrinkles than women.

Design supports claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The claim uses 'associated with,' which correctly reflects observational data from epidemiological studies. It does not claim causation (e.g., 'causes'), which is appropriate since sun exposure cannot be randomly assigned in humans. The linear relationship and sex difference are plausible and commonly reported in dermatological literature. No overstatement is present; the claim is cautious and aligns with known evidence.
More Accurate Statement
“Chronic lifetime sun exposure is associated with an increased number of facial wrinkles in adults, with the number of wrinkles increasing approximately linearly with age, and men tending to show more wrinkles than women.”

This study found that people who spent more time in the sun over their lives had more wrinkles, especially as they got older, and men had more wrinkles than women — just like the claim says.
