People who swallow hyaluronic acid supplements—whether they’re big or small molecules—tend to have moister skin, which suggests the size of the molecule doesn’t matter for this effect.
Claim Language
Language Strength
association
Uses association language (linked to, correlated with)
The claim uses the phrase 'are associated with', which indicates a statistical link or correlation rather than a direct cause. The phrase 'suggesting the effect is not dependent on molecular size' further reinforces a correlational interpretation without asserting causation.

Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies

Ingested hyaluronan moisturizes dry skin
The study says taking HA supplements can make skin moister, but it doesn’t say whether big or small HA molecules work better — so we can’t tell if the claim about both working the same is true.
