Science
Mechanism of Action
This ingredient works through several key mechanisms to improve skin health. It fortifies the skin's natural barrier against environmental aggressors like pollution and UV radiation, utilizing its rich composition of fatty acids, hydrating polysaccharides, and carotenoids such as zeaxanthin, which provide antioxidant protection. For moisturization, it significantly enhances the expression of HAS-2, a key enzyme in hyaluronic acid synthesis, and contributes hygroscopic components that mimic the skin's natural moisturizing factors. Its anti-aging efficacy stems from stimulating collagen-I synthesis, boosting fibroblast activity to improve connective tissue structure, and increasing skin elasticity. Furthermore, it actively reduces the appearance of wrinkles by suppressing MMP-1 expression and inhibiting elastase activity. The ingredient also exhibits potent anti-inflammatory effects by rebuilding the extracellular matrix, protecting against UVA/UVB damage, restoring cellular redox balance, and modulating inflammatory signaling pathways, making it particularly beneficial for sensitive skin. Overall, its lipid, protein, vitamin (C, B12), and mineral content supports comprehensive skin conditioning, revitalization, and cell renewal.

Key findings
- 01 An extract from Nannochloropsis sp. G1-5, at 0.1% w/v (1000 μg/mL), substantially increased HAS-2 expression by up to 274.58%, indicating a significant moisturizing effect. Concurrently, it demonstrated anti-wrinkling benefits by suppressing MMP-1 mRNA expression up to 26.71% and increasing Col1A1 mRNA expression by up to 15.53%. Additionally, it inhibited elastase activity by up to 24.88%.
- 02 Lipid extracts from Nannochloropsis oceanica, at a concentration of 0.0002% w/v (2 µg/mL), safeguarded human skin fibroblast metabolism from UVA-induced damage. This protective action involved restoring redox balance and regulating inflammatory signaling pathways. Furthermore, it reduced levels of inflammatory markers such as sphingomyelin, lysophosphatidylcholine, TNFα, 8-iso prostaglandin F2, and 4-HNE-protein adducts in UVB-irradiated keratinocytes, suggesting potent anti-inflammatory and pro-survival effects.
- 03 When included in a cosmetic blend (Marine BlueRevelation 50+™), Nannochloropsis oceanica extract yielded notable improvements over two months. Skin hydration increased by 33%, skin elasticity improved by 20%, and the visibility of wrinkles was significantly reduced by 26%.
