User blog comment:BlackWizardZeref/Fairy Tail Chapter 394: Juvia vs Keith Review/@comment-24066070-20140725100139/@comment-24066070-20140725104446

Silver did tell Juvia that Face was now stopped and I assume he knows how Keith's Curse works considering he was a victim of it himself.

So I think it's safe to consider Face stopped for now, unless Marde knows another way to activate it.
