Science
Mechanism of Action
This extract contains an array of bioactive constituents, including premnine, 7-deacetylpremnine, premnalatifolin, and quercetin, similar to other species within the Premna genus. These compounds, alongside iridoids, flavonoids, and phenols, are hypothesized to exert their effects by modulating inflammatory pathways, neutralizing oxidative stress, and inhibiting bacterial growth. Such actions collectively support skin health by reducing irritation, protecting against environmental damage, and promoting a balanced skin microbiome.

Safety
Safety Profile
Formal safety assessments by recognized regulatory bodies such as CIR, SCCS, or FDA for Premna Mollissima Leaf/Root Extract as a cosmetic ingredient are not readily available in scientific literature. Paula's Choice categorizes this ingredient as 'Not rated' due to insufficient data. Historically, Premna mollissima and related species have been utilized in traditional medicine for various skin conditions, implying a history of topical use, but this does not equate to modern cosmetic safety evaluation.
