Summary

This study tested whether a daily cream with antioxidants and SPF 50 protects skin DNA from sun damage better than a cream without these ingredients. Fifty-two healthy adults used the assigned cream on their face every day for 12 weeks. Researchers took cheek swabs at the start and end to measure DNA damage. The goal was to see if adding antioxidants to sunscreen offers extra protection against everyday sun exposure.
