Uses definitive language (causes, prevents, cures)

Oral administration of hyaluronic acid to improve skin conditions via a randomized double‐blind clinical test
The study says taking HA pills can make skin more hydrated and thicker, but it didn’t test the exact dose, type, or stress conditions mentioned in the claim, so we can’t say it proves the claim.
