Question 5

How does Phaeodactylum Tricornutum Extract work chemically?

Accepted Answer

This is a complex marine microalgal extract containing carotenoids such as fucoxanthin, omega-3 lipids, amino acids, polysaccharides, minerals, and other secondary metabolites, with composition shaped by cultivation and extraction conditions. It is usually used at low cosmetic levels, and formulators protect it from excess heat, oxygen, and light because carotenoid-rich fractions can oxidize over time.
