Problem, agitate, solution turns up in briefs more than any other structure, usually as a bullet point. It works on a page. It breaks in one predictable place when a face delivers it, so here is the break and what I do instead.
Where it breaks: the agitate beat
On a page, agitation reads as empathy with momentum. The reader is alone with text and can leave whenever they like. On camera, the same escalation comes from a person looking straight at the viewer, and it reads as being told what is wrong with you.
Written, it is standard direct response: "and it only gets worse, and you have probably noticed it is affecting how you feel about yourself." Said aloud by someone holding a bottle, it is an insult. The viewer's reaction is not "I should fix this," it is "who asked you."
Beauty is where this is sharpest, because the problems are about faces and bodies. If the brief needs the agitate beat at full strength, that is a different creator, and I say so at the enquiry stage rather than after the shoot.
What I do instead
I cut it to one sentence and make the sentence about me. "It got to the point where I stopped bothering" does the work of three sentences of escalation. The problem had a cost, nobody is being diagnosed, and the viewer reaches the conclusion on their own. First person, past tense, one sentence.
Keep the problem narrow and the ending small
Briefs tend to size the problem at market level: "busy women struggle to keep a consistent routine." Nobody recognises themselves in a segment. One specific circumstance, like putting something on and watching it just sit there, reaches more people than the category does.
The ending has the same trap. A total resolution undoes the credibility the first two beats built. "It helped, and here is specifically what changed" is easier to believe, stays inside the claims list in the brief, and is the version that does not get pulled a week after it goes live.
When I would not use it
PAS needs a problem, and plenty of products do not have one. Fragrance has none, and colour cosmetics mostly do not. Forcing the formula there means inventing a problem, and invented problems are audible. A narrative structure or plain demonstration does more, and the format is worth choosing deliberately rather than taking whatever the brief template defaulted to.
What to put in the brief instead of "use PAS"
The one circumstance in which someone reaches for this product, and what it honestly does and does not do. I will find the structure on the day, and it will usually look like PAS with a one-sentence middle. Book it that way and the next product goes faster, because by then I know who reaches for your range and when.
Common Questions
Does the PAS formula work for UGC video?
The spine works, but the middle step breaks. Agitation that reads as empathy on a page reads as being told what is wrong with you when a face says it.
How do you adapt the agitate step?
Cut it to one sentence about yourself, not the viewer. "It got to the point where I stopped bothering" carries the same weight without diagnosing anyone.
How specific should the problem be?
One circumstance, not a segment. "Busy women struggle with routines" describes a market, and nobody recognises themselves in it.
When should PAS not be used?
When the product has no real problem, as with fragrance and most colour cosmetics. Invented problems are audible.
