Needed. Collagen: Ad Behaviour & Psychology

The psychology:This leverages Authority Transfer and Social Proof: the phrase “knows what she’s talking about” borrows perceived expertise, and the “ever since I’ve been taking collagen” detail makes the claim feel like lived evidence rather than marketing. It also uses Commitment/Consistency Bias—once the viewer hears the speaker has been taking it continuously, they’re more likely to assume the outcome is stable and worth trusting.

The psychology:This leverages Measurable Transformation by using a strong magnitude cue (“so much better”) and extending it to multiple outcomes (“hair” and “skin”), which makes the result feel concrete and transferable. The viewer’s brain treats the repeated “has been better” phrasing as evidence of consistent payoff, reducing skepticism and increasing trust that the method/product delivers real change.

The psychology:This leverages Cost/Benefit Reframe by making the downside vivid (“wasting my money”) and tying it to a specific prior experience (“taken other collages… didn’t notice anything”). That activates Loss Aversion: the viewer mentally avoids the possibility of paying for something that won’t deliver noticeable results, so they stay attentive to what makes the “equally” part true.

The psychology:This leverages Before/After Proof by contrasting the pre-switch state (“for the first time” noticing) with the post-switch state (“noticing a difference”). That contrast reduces skepticism because the change is attributed to the specific action (“switching over to natives collagen”), making the viewer more likely to believe the method caused the improvement.

The psychology:This leverages Belief Break by shattering a commonly held assumption (“time of month = skin problems”) and swapping in a more helpful replacement (“it doesn't even matter”). Because the correction is framed as direct evidence (“consistently clear,” “still glowing”), the viewer’s brain updates the causal story, which reduces uncertainty and increases the urge to keep watching for the mechanism behind the claim.

The psychology:This leverages Commitment Bias and Actionability: once the viewer has decided they “want to learn more,” the instruction “click the link below” removes ambiguity and converts that intention into a concrete next step. It also uses Friction Reduction by minimizing effort—no extra thinking, just one clear action tied to their stated goal.

The psychology:This leverages Goal-Gradient Effect and Implementation Intention framing: once the viewer mentally links their desired outcome to the specific action (“start taking this collagen”), the brain treats it as the most direct path. The “definitely should” language adds Social Proof/Normative Pressure, making the recommendation feel like the expected choice rather than an optional experiment.
