Science
Mechanism of Action
This extract functions as a powerful humectant, restoring and maintaining optimal skin moisture balance. Its strong antioxidant capacity neutralizes free radicals, safeguarding the skin from environmental stressors like UV radiation and pollution. Through stimulating collagen production, inhibiting elastase, and inducing DNA repair gene expression, it actively combats photoaging and improves skin elasticity. Furthermore, it reduces redness and discomfort by decreasing nitric oxide and inflammatory cytokine production, while its antimicrobial effects may assist in managing acne and its antioxidant properties contribute to a brighter, more even skin tone. Key beneficial compounds include inositols, beta-carotene, and essential minerals.

Key findings
- 01 Human efficacy trials demonstrated a 19% improvement in skin texture and 20% pore refinement after six weeks of use, with visible smoothing of fine lines around the eyes.
- 02 Clinical studies show a significant increase in skin hydration compared to untreated skin.
- 03 Research indicates a significant increase in antioxidant and collagen-promoting genes post-sun exposure, effectively reducing photoaging damage.
- 04 In vitro, a hot water extract at 400 µg/ml exhibited 62.9% DPPH radical scavenging activity, while an ethanol extract at the same concentration showed 51.3% activity. A heated extract at 2 mg/mL achieved 75.5% DPPH radical scavenging activity.
- 05 Concentrations of 100-300 µg/mL significantly decreased the production of nitric oxide (NO) and inflammatory cytokines (TNF-α, IL-6, IL-1β), confirming anti-inflammatory effects.
- 06 At 600 mg, the extract demonstrated antibacterial activity against Pseudomonas aeruginosa (MIC 6.6%), Escherichia coli (MIC 19.8%), and Staphylococcus aureus (MIC 12.5%).

The Formula
Formulation
Stability
The incorporation of Mesembryanthemum crystallinum extract can lead to a reduction in formulation viscosity and pH. Formulations containing this extract have shown a notable loss of total antioxidant capacity after 15 days of storage at 4°C, indicating a potential for instability that requires careful consideration during product development.
Safety
Safety Profile
Although the Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed Mesembryanthemum crystallinum extract, studies suggest it is generally well-tolerated, with rare reports of mild allergic reactions such as skin irritation or itching. Its safety for cosmetic use is supported by regulatory authorities like the European Cosmetics Regulation. SkinSAFE categorizes it as 'Irritant Free', 'Fragrance Free', and 'Paraben Free', suggesting a favorable profile for sensitive skin.
