The Proshare face-spray brochure includes timelines for absorption, firming and visible change. An informative product discussion asks what those timelines measure and whether they came from testing of the actual finished spray.

Define the outcome

Absorption, hydration, firmness and perceived age are different outcomes. Ask which one was measured, how it was measured and whether the result was compared with a control. A single photograph cannot answer every question about a skin-care product.

Make comparisons consistent

If you keep your own photographs, use the same lighting, angle, distance and camera settings. Note other changes in your routine. Consistency makes a personal record more informative, although it does not turn that record into a controlled product trial.

Keep testimonials in their proper role

An individual's experience can explain why they like a cosmetic. It cannot guarantee the same response for another person or establish a clinical effect. Request fuller evidence where a brochure makes a precise performance claim.

TAKEAWAY

Appearance claims are easiest to assess when the outcome, method and finished-product evidence are clearly stated.
