Sun Protection Behaviors Assessed Via QuestionnairesPrimary· Weeks 0 (Visit 1), 4 (Visit 2), 8 (Visit 3)
Mean and standard deviation for each sun protection behavior at Visit 1 (baseline), Visit 2 (4 weeks), Visit 3 (8 weeks).
"These next questions ask about what you have done in the past four weeks if you were outdoors in the sun for 15 minutes or more. How often did you... " Minimum value =1; Maximum value= 5; Higher scores indicate that participants were more likely to engage in sun protection habits.

Participants will be randomly assigned to one of four groups, the group will be in is decided by chance. Participant will either be assigned to:
* A group that gets advice about what causes skin cancer and how to prevent it
* A group that gets this advice and provides a saliva sample to receive personalized skin cancer risk genetic testing results
* A group that gets this advice and receives a personalized photo that shows existing skin damage
* A group that gets this advice, receives genetic testing results, and receives a personalized photo.
