Porphyridium Polysaccharides
What is Porphyridium Polysaccharides?
Porphyridium Polysaccharides are complex polysaccharides extracted from the unicellular red microalgae Porphyridium cruentum, known for their potent moisturizing and protective properties. These bioactive compounds form a breathable film on the skin, enhancing hydration by binding water and shielding against environmental stressors like pollution, UV radiation, and free radicals. They also exhibit anti-inflammatory effects and promote skin barrier repair, making them a valuable ingredient in advanced skincare formulations.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Skin protecting
Forms a barrier to protect skin from external irritants.
Humectant
Attracts and holds water in the stratum corneum, boosting hydration and plumpness; commonly used in moisturizers, cleansers, and hair conditioners.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Soothing
Helps reduce the feeling of discomfort and visible irritation by supporting skin calmness, often through anti-irritant, barrier-supporting, or cooling mechanisms.
Antioxidant
Slows oxidation of oils, fragrances, and sensitive actives to improve shelf life and reduce rancidity or color change; sometimes also supports skin protection from oxidative stress.
