Haslea Ostrearia (Blue Algae) Extract
What is Haslea Ostrearia (Blue Algae) Extract?
Haslea ostrearia is a marine diatom microalgae, a type of unicellular algae found in coastal environments like the French Atlantic shores. It produces marennine, a unique blue-green pigment through photosynthesis, which gives the extract its distinctive color. The extract is derived from cultivated cells of this microalgae and belongs to the category of botanical extracts in cosmetics. Typically incorporated into creams, serums, and masks at low concentrations, it functions primarily as a skin conditioning agent. Its polysaccharides and bioactive compounds help form a lightweight film on the skin surface, aiding in moisture retention and enhancing texture without greasiness. This mechanism supports the skin's natural barrier, contributing to a supple feel.
