Objective : The aim of this study is to assess the effect of Korean Herbal Cosmetic on quality of life (QoL) of Korean Herbal Cosmetics Using Dermatology Life Quality Index (DLQI) stratified by blind versus non-blinded option.
Methods : Forty five healthy females aged 30's to 40's were recruited for this study. Volunteers were divided into two groups : Group A (n=22) was provided an anti-aging cream with ginseng extract in the original packaging including the brand name and logo. Group B (n=23) were provided same cream in a plain white normal jar without any package decoration or logo.
Results : All females except two volunteers in group A completed a DLQI questionnaire, baseline, after 4 weeks and 8 weeks of treatment. The baseline of DLQI scores of all groups was 3.23±2.72. There was a significant difference in DLQI scores between before, 4 weeks and 8 weeks after in both groups ; The scores changed from 4.25±3.45 to 0.95±1.15 at 4 weeks, 1.00±1.72 at 8 weeks in group A, The scores of group B changed from 2.35±1.47 to 0.83±1.23 at 4 weeks, 0.65±0.98 at 8 weeks. But both had no interaction effect between follow up times and groups. Subscale DLQI scores improved after 4weeks were 'Symptoms and feelings', only in group B
Conclusions : Both groups showed significant improvements in QoL quality scores evaluated by DLQI. However, interaction was not observed for whether the participants knew the brand and content of the cream.
