In smoothness, although the calculated value in the control + UVB (32.5 ± 2.6), AE + UVB
(30.5 ± 1.5), and CP + UVB (30.9 ± 1.9) was significantly larger than that in the control group (26.5 ± 1.9) at week 7, there was no significant difference between the control group (26.5 ± 1.9) and AECP + UVB group (28.8 ± 1.6).
