A closer look
What the research shows
Safety assessment
The assessment examines cosmetic irritation, sensitization and toxicology, with dermal evidence including a 3% myo-inositol face cream use study.
What this does not tell us
Safety assessment under described cosmetic exposure, not a skin benefit trial. Isomer-specific oral or reproductive observations do not establish topical efficacy.
