Figure 7
Exfoliation efficacy changes of CAR as mixed with BT, HQ, HSC. Exfoliation efficacy for each sample is represented as the SC turnover time for 50 percent SC exfoliation (a). Untreated case is used as negative control. The dose of CAR is 0.5 wt% and BT, HQ or HSC is mixed as 1:1 molar ratio with CAR. Data are means and bars represent the standard deviation. P-value for CAR is vs. negative control and for each mixture is vs. CAR only. *p < 0.05, **p < 0.01, ***p < 0.001; Student’s t-test. Correlation between the penetration amount of CAR and its exfoliating efficacy is represented in (b).
