Here's my 4 month update on Formulogic's Barrier Cream

Formulogic's Barrier Cream: ACTS - it is applied to the skin and its results are discussed. Removing it would change the video's topic. (a) it ACTS — its interface is operated, it generates or edits something, a visible result comes from it, or someone says what it does for them; (b) it merely APPEARS — a corner watermark, a channel or studio logo, an end card, a credit, a name on clothing, a repost stamp. For each, say whether removing it would change what happens in the video. "none" if no names appear.
