Bias, funding and generalising research claims
Industry funding is important information, not an automatic verdict. Learn selection, performance, detection, reporting bias and whether a small trial's participants resemble the people a brand addresses.
Three biases you can spot
Selection bias arises if participants or group assignment systematically differ. Detection bias can occur when an assessor knows the intervention and grades a subjective outcome. Reporting bias appears when only favourable outcomes are highlighted. Check study registration and protocol where available, and ask whether all recruited participants are accounted for.

A brand-funded trial can be well designed, and an independent trial can have methodological flaws. Funding and author affiliations should be reported so readers can examine possible incentives and safeguards: independent analysis, blinding, preregistration and access to methods. Neither 'independent' nor 'clinically proven' is a quality score by itself.
Who was missing from the study?
A trial including only healthy adults with light skin tones may not justify equally strong claims for teenagers, darker skin tones, pregnancy or people with active dermatitis. Inclusion and exclusion criteria, geography and climate affect applicability. Do not assume that a formula shown safe for one group is clinically verified for all others.
The image is about consent, not skincare efficacy
The real, licensed NIAID photograph shows informed consent for a clinical trial, not participants in a SESH trial. Ethical oversight matters, but a photo of consent does not establish low risk of bias or efficacy; inspect the study's actual trial documentation.

Hypothetical: a study funded by its manufacturer excludes sensitive skin, loses 30% of participants and reports only the best of 12 outcomes. A competitor has no funding but no control group. Which earns an unqualified recommendation?
Defensible interpretation
Neither. Funding is a cue for scrutiny, while selective outcomes, missing data and lack of a comparator directly threaten inference. Report limitations for both and withhold universal claims.
