Science
Mechanism of Action
Rich in natural antioxidants like vitamin E, carotenoids, chlorophyll, and tocopherols, Tetraselmis Suecica Extract significantly reduces oxidative stress by neutralizing free radicals, thus stimulating cellular repair. It offers comprehensive anti-photoaging benefits by shielding human skin fibroblasts from UVB-induced damage, downregulating Matrix Metalloproteinase-1 (MMP-1), and enhancing type 1 procollagen synthesis for improved skin structure. Furthermore, this extract exhibits anti-inflammatory effects by reducing pro-inflammatory factors and inhibiting prostaglandin E2 release, providing soothing relief. It promotes tissue repair, aids in regulating sebum production, fortifies the skin barrier, and demonstrates prebiotic efficacy to support a healthy skin microbiome.

Key findings
- 01 Studies demonstrate potent antioxidant activity, with an IC50 for DPPH radical scavenging observed at approximately 0.0037% (37.320 ppm).
- 02 In human fibroblasts, concentrations from 0.0031% (31 µg/ml) to 0.05% (500 µg/ml) significantly inhibited intracellular Reactive Oxygen Species (ROS) production following UVB irradiation in a dose-dependent manner. This range also protected type 1 procollagen from UVB-induced depletion and reduced MMP-1 expression, with no observed cytotoxicity up to 0.05%.
- 03 Clinical and ex-vivo evaluations using the ingredient as part of a proprietary complex showed significant reductions in sebum overproduction, enhanced skin soothing, and strengthened skin barrier function, alongside prebiotic efficacy.

Stability
While direct pH stability for the extract is not definitively specified, a related protein isolate from Tetraselmis sp. demonstrated complete solubility above pH 5.5 and stable emulsion/foam characteristics within the pH 5-7 range, suggesting potential compatibility for the extract in similar pH environments.
Safety
Safety Profile
Official safety assessments by CIR, SCCS, or FDA are currently unavailable. However, laboratory studies indicate no cytotoxicity was observed in human fibroblasts even at concentrations up to 0.05% (500 µg/ml).
