Clinical assessment. Subjects were clinically assessed
for appearance of fine lines and coarse wrinkles as well as
signs of uneven pigmentation; lack of elasticity, resilience,
and radiance; skin tone; tactile roughness; and overall
appearance. Subjects also completed a self-assessment
questionnaire to assess skin condition in terms of facial
lines and wrinkles; the appearance of brown spots and
facial discoloration; and overall skin tone (firmness,
dryness, radiance and texture, and the appearance of
pores). Using 10-point scales, clinical evaluations (where
0=none, 1–3=mild, 4–6=moderate, and 7–9=severe) and
subject self-assessments (where 0=most positive response
and 9=most negative response) were conducted at
Baseline (Visit 1) and Weeks 4, 8, and 12. Mean and
average percent change from Baseline and percent of
subjects showing improvement were calculated at each
visit. Subject opinion of current facial skin condition was
recorded at Baseline and Week 12 and improvement/
changes to skin condition since the start of the study at
Weeks 4, 8, and 12.
