A closer look

What the research shows

Safety assessment

The published assessment reviews available safety data for the three sugar alcohols in the stated cosmetic uses and concentrations.

What this does not tell us

Safety assessment is distinct from skin benefits. Injectable hyaluronic acid fillers containing mannitol cannot isolate topical mannitol efficacy.
