Science
Mechanism of Action
This extract functions as an anti-inflammatory agent primarily by leveraging its rich content of arachidonic acid (AA), a precursor to physiologically active prostaglandins (PGs). These compounds contribute to boosting the skin's intrinsic immune response. Furthermore, it exhibits direct antioxidant activity, safeguarding cellular DNA from UV-induced damage.

Key findings
- 01 In UVB-irradiated mice models, a 5% cream extract demonstrated significant antioxidant activity (over 50% scavenging) and reduced epidermal thickness and erosion.
- 02 A 10% cream extract further enhanced these effects, showing superior antioxidant activity (also over 50% scavenging) and a more pronounced reduction in epidermal damage, yielding results comparable to normal skin.

Stability
No specific optimal pH range for the extract's stability in cosmetic formulations has been identified. However, for agar extraction from related Gracilaria species, alkaline conditions (3-10% w/v) are typically employed, followed by neutralization.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR), Scientific Committee on Consumer Safety (SCCS), and U.S. Food and Drug Administration (FDA) have not specifically reviewed Gracilaria vermiculophylla Extract. While CIR has reviewed related 'brown algae-derived ingredients', no specific safety assessment is available for this red alga extract, leaving its sensitization potential undetermined.
