Why are the red pigments important?

What makes Porphyridium so special is its content of phycoerythrin and rare sulfated polysaccharides, which stand out for their antioxidant properties. The colour pigments are not only used for decorative cosmetics but also actively contribute to the elasticity of the skin.

The main application of Porphyridium cruentum is currently in anti-aging products and skin protecting creams. The special combination of vitamins, antioxidants and pigments offers the skin protection against damaging external influences.

The fact that Porphyridium cruentum is so rich in polysaccharides and antioxidants makes it ideal for creams. The cream Couperose Relax is offered intensively from the product line “Exquisit” by Hildegard Braukmann.
