Science
Mechanism of Action
This extract enhances skin hydration by forming a protective barrier via sulphated phycocolloids and diffusing osmoregulating molecules to fortify the natural moisturizing factor (NMF), thus creating a deeper water 'reservoir' within the skin. Functioning as a potent humectant and thickening agent, it actively revitalizes, remineralizes, and stimulates both blood circulation and cell renewal. Additionally, it offers potential benefits in stimulating collagen synthesis, alongside exhibiting antioxidant and photoprotector bioactivities.

Key findings
- 01 A 5% concentration of Monostroma species extract demonstrated potential skin moisturizing activity, as objectively measured by a corneometer on the inner forearm skin of 10 women.
- 02 Water-soluble mucilage from Monostroma nitidum (a related species) utilized in moisture masks, significantly decreased film formation time with increasing concentration, while effectively acting as both a humectant and a thickening agent.

Safety Profile
The Cosmetic Ingredient Review (CIR) has identified Monostroma Obscurum Extract as having insufficient data to reach a conclusive safety determination. However, a Draize score test conducted on water-soluble mucilage from the related species, Monostroma nitidum, showed no incidence of erythema, suggesting a low potential for skin sensitization or allergic reactions.
