This is based on a universal insight that women check themselves out whenever there is a reflection / mirror, and especially if they think no one is watching.  Our protagonist enters a lift and starts to check herself out, and then realizes that there is a security camera watching her.  But she is unfazed because she uses CLEAR; she knows her dandruff never comes back, she is confident that she looks good.

You can tell the world to keep watching.  With Clear, you have no dandruff.  You have nothing to hide.
