Ok, this is not as "dumb" as it seems, I am using a night cream (a bleach cream to be specific) and it says I am meant to pat it at night- however the confusion is that I am not sure that when I wake up if the cream is still meant to be present or if it is meant to "dissolve" away as usually the cream will not be present and only a fairly small amount of the cream will be visible in the morning...
Thanks a lot
