Twenty-two subjects were initially enrolled in the clinical trial. One subject was excluded by non-compliance with the plan of trials. All subjects used the placebo sample on the left side of their face and the investigational sample on the right side of their face, respectively. The moisturizing levels were detected before use (0 week), after 2 weeks and after 4 weeks. The crow's feet of subjects were also measured on the same date interval as the skin moisture level test.
