Porphyridium
Porphyridium is a nutrient-rich red microalga extract used in modern skincare for its soothing and hydrating properties. Grown sustainably in controlled environments, it delivers a natural polysaccharide that helps skin feel smoother and more comfortable. It is a favourite in clean-beauty formulas for its gentle yet effective performance.
How it works in skincare
In cosmetics Porphyridium is valued for the sulphated exopolysaccharides it produces. These naturally occurring molecules form a lightweight, breathable film on the skin that helps bind moisture while calming feelings of discomfort. The extract is also rich in natural pigments, proteins and essential fatty acids that support a healthy-looking complexion without greasiness, making it ideal for lightweight serums, creams and after-sun products.
