Lithamnion calcareum extract is the extract from a red algae species. The red algae (Rhodophyceae) are a widespread algae species that occurs in all seas. In photosynthesis, they use the red-coloured phycobiliproteins instead of chlorophyll, which explains their red colouring. The extract is used in cosmetic formulations. It protects the skin from harmful effects of external factors.
