Changes in Self-Perceptions of Photoaging Severity and Skin Cancer Risk After Objective Facial Skin Quality Analysis

Background: Despite public education efforts, many people at risk for skin cancer do not practice safe sun behaviors.

Objective: To determine whether machine-based evaluation of UV-induced alterations (VISIA scan) changes self-assessment of facial photoaging, skin cancer risk, and willingness to improve sun protective habits. In addition, to determine whether VISIA scan analysis reveals differences between those with versus without a history of skin cancer, men versus women, those older than 50 versus less than 50 years of age, and Fitzpatrick skin types I-III versus IV-VI.

Methods: Volunteers attending a health expo were recruited and queried about their perceived risk of skin cancer and degree of skin photoaging. All participants underwent facial skin quality analysis of both sides of the face, and then completed a follow-up survey.

Results: Participants' scored self-perceptions of overall skin aging were all statistically significantly worse after VISIA scan analysis. There was no change in perceived skin cancer risk, but most participants expressed intent to improve their sun protection habits.

Limitations: Limitations to this study include selection bias, recall-misclassification bias, and social desirability bias.

Conclusion: Intervention with facial skin analysis can positively affect subjects' stated intent to use sun protection, indicating the importance of appearance in these health decisions.
