The ingredient narratives reshaping clean beauty.
Malassezin
A January 2026 split-face human study offers encouraging pigment-focused evidence, while Mother Science gives the molecule a broader consumer route. This dossier is new to the library; the study and retail expansion are earlier events.
- early human evidence for improvement in uneven pigmentation under studied conditions
- pigment-focused facial skincare
The study tested 0.75% malassezin against 4% hydroquinone over 12 weeks. That concentration is study-specific, not a universal use recommendation.
Twenty adults with mild-to-moderate melasma is a small cohort. No significant between-treatment difference does not prove equivalence, superiority, universal safety or performance across formulas.
Emerging — promising human evidence with formula, rights and replication questions still open.
