Abstract:

In this study, the inhibitory effect of corn silk on melanin production was evaluated. This study was performed to investigate the
inhibitory effect of corn silk on melanin production in Melan-A cells by measuring melanin production and protein expression.
The corn silk extract applied on Melan-A cells at a concentration of 100 ppm decreased melanin production by 37.2% without
cytotoxicity. This was a better result than arbutin, a positive whitening agent which exhibited a 26.8% melanin production inhibitory
effect at the same concentration. The corn silk extract did not suppress tyrosinase activity but greatly reduced the expression of
tyrosinase in Melan-A cells. In addition, corn silk extract was applied to the human face with hyper pigmentation and skin color was
measured to examine the degree of skin pigment reduction. The application of corn silk extract on faces with hyper pigmentation
significantly reduced skin pigmentation without abnormal reactions. Based on the results above, corn silk has good prospects for use
as a material for suppressing skin pigmentation.
