Questions

How does it stop the diagram from overclaiming?

Every statement lives in a ledger with its status and source. A check script rejects cure and treatment wording, percentages or timeframes without a matching citation, brand statements drawn as mechanisms, and arrows drawn in the wrong evidence style.

Does the image model write the labels?

No. PopNow paints only the unlabeled skin block. Layer names, arrows, claim cards, citations and the disclaimer are typeset afterwards, so the words are exact and can be changed without paying for a new image.

Can it say a product is clinically proven?

Only on a claim marked established or emerging whose citation reports exactly that, and the card always shows the source. Without one the check fails and the wording has to change.

What does one diagram cost?

Usually one image. The skill shows the exact price and your balance before anything runs and waits for your yes.

Is the skin structure diagram accurate enough for a product page?

The layers, from the stratum corneum down to the dermis, follow a standard skin structure diagram, and every label is typeset rather than drawn. Each ingredient claim needs a source you supply, so the labeled skin diagram never says more than your evidence.
