Summary

This study looks at whether using sunscreen on a healing surgical scar improves how it looks. Fifty adults who had skin cancer surgery will have half of their scar treated with sunscreen and the other half left alone. After three months, doctors will compare the two sides to see if sunscreen helps reduce redness, dark spots, and overall scar appearance.
