In depth
What it does
An extract of red microalgae (Porphyridium cruentum) rich in sulfated polysaccharides, used for its water-binding and antioxidant properties. As an humectant ingredient, it is particularly valued for polysaccharide-rich extract that helps skin retain water and antioxidant support via phycoerythrin and other pigments.
Skin type guide
Works across all skin types, but is especially beneficial for dry and dehydrated skin. Oily skin types also benefit — proper hydration helps regulate sebum production.
How to use it
Apply to slightly damp skin to maximise moisture retention — humectants work by drawing water to the skin, so they need a water source to pull from. Use early in your routine, before heavier creams or oils.
