Science

Mechanism of Action

Nannochloropsis Oceanica Extract forms a protective barrier, shielding skin from environmental stressors such as pollution, harsh weather, and UV radiation, thereby preserving natural moisture balance. Its rich composition of polyunsaturated fatty acids (PUFAs), carotenoids, and phenolic compounds provides potent antioxidant and anti-inflammatory benefits, protecting keratinocytes against UVB damage and mitigating inflammatory responses. The extract actively supports anti-aging by suppressing MMP-1 (collagen-degrading enzyme) expression by up to 26.71%, promoting Col1A1 (collagen synthesis) gene expression by up to 15.53%, and inhibiting elastase activity by up to 24.88%. It further aids skin health by boosting cell renewal, offering revitalizing and re-mineralizing effects, and acting as a powerful humectant to enhance moisturization. Additionally, it helps to balance the skin microbiome and reduce immune-mediated inflammation, particularly benefiting sensitive and atopic skin.

Key findings

  1. 01 An in vitro study using Nannochloropsis sp. G1-5 extract demonstrated a significant anti-aging effect, suppressing MMP-1 mRNA expression by up to 26.71%, increasing Col1A1 mRNA expression by up to 15.53%, and inhibiting elastase activity by up to 24.88%.
  2. 02 In vitro studies utilizing Nannochloropsis oceanica lipid extracts showed protection for skin fibroblasts against UVA-induced damage by restoring redox balance and modulating inflammatory pathways.
  3. 03 A clinical study involving a product cocktail, including Nannochloropsis oceanica extract (Marine BlueRevelation 50+™), reported increased skin hydration by 33%, skin elasticity by 20%, and reduced wrinkle visibility by 26% after two months of use. The specific concentration of N. oceanica extract within the cocktail was not provided.

Stability

The natural bioactive compounds in microalgal extracts can exhibit chemical instability and poor solubility in topical applications, suggesting encapsulation may be beneficial for enhancing stability and bioactivity. Lipid extracts containing polyunsaturated fatty acids (PUFAs) are sensitive to degradation at higher temperatures during extraction, indicating a need for careful processing and storage.

Sensitization risk Low

In vitro studies consistently show low cytotoxicity for Nannochloropsis species extracts. Nannochloropsis gaditana extract was found to be non-irritating to human skin, with cosmetic formulations containing it proving mild after 16 hours. The species does not produce toxins, and its safety is supported by its historical use in aquaculture. Nannochloropsis Oceanica Oil, a derivative, has a low comedogenicity rating of 2 out of 5.
