Visia® Filter Data
The Canfield Visia® assigns percentages to each participant’s photos at each time of imaging. A lower percentage indicates a worse condition in relation to other people of their age globally. Improvement is indicated by a percentage that increases, closer to 100%. The statistical analysis indicated significant improvement in brown spots (P=.002; Figure 3), rhytids (P=.002; Figure 4), and skin texture (P=.003). Directional improvement in red areas was indicated (P=.055).
Self-Assessment Questionnaire
The self-assessment questionnaires were completed at each visit. Participants were asked: "On a scale of zero to four, how would you rate the overall appearance of your facial skin? Zero - no improvement, One - mild improvement, Two - moderate improvement, Three - moderately significant improvement, Four - significant improvement”, at week 12, 100% of participants rated themselves a four, "significant improvement" (Figure 5).
