Phaeodactylum Tricornutum Extract
What is Phaeodactylum Tricornutum Extract?
Phaeodactylum tricornutum extract derives from a unicellular diatom microalgae abundant in marine environments. This silica-shelled alga yields polysaccharides, lipids, carotenoids such as fucoxanthin, and polyunsaturated fatty acids through aqueous or solvent extraction methods. In cosmetics, it features in moisturizers, serums, and protective creams. Functioning as a humectant, it binds water molecules to the skin's outer layer, promoting moisture retention and improved texture. Its natural compounds contribute soothing effects by modulating skin responses to stressors. Additionally, the extract's lipid profile supports barrier integrity, aiding overall skin resilience in daily formulations. Sourced sustainably from controlled cultures, it integrates well into water- and oil-based products for broad application.
