A closer look

What the research shows

Laboratory and human research

Oatmeal extracts altered barrier-related gene expression in vitro; a 50-woman investigator-blinded lotion study reported better dryness and barrier measurements.

What this does not tell us

Solvent extracts and lotion combinations do not isolate flour efficacy; absence of a clear vehicle comparator in the abstract limits causal inference. Grain preparation must match colloidal oatmeal.
