THALASSIOSIRA PSEUDONANA EXTRACT.

This extract operates through several pathways, primarily due to its rich composition of fatty acids, including myristic, palmitic, and palmitoleic acids, which may contribute to its potential antiparasitic, antiviral, antifungal, and antiproliferative activities. A significant mechanism is its robust antioxidant capacity, demonstrated by an IC50 value of 83.34 µg/mL and a high total polyphenol content of 174.48 GAE/g, actively mitigating oxidative stress. As a marine microalga, it is understood to enhance skin hydration, support blood circulation, stimulate cell renewal and metabolic processes, help regulate sebaceous gland function, impart anti-inflammatory benefits, and fortify the skin's natural resistance. The presence of polar lipids, essential structural components during its life cycle, further suggests its role in providing emollient effects and strengthening the skin barrier.
