Porphyra Tenera Extract
What is Porphyra Tenera Extract?
Porphyra tenera extract comes from a marine red alga known as a nori seaweed species, harvested from coastal waters. This botanical extract contains polysaccharides, proteins, vitamins like A, C, and E, and minerals such as iodine and zinc. In cosmetics, it serves primarily as a skin conditioning agent. It works by forming a protective film on the skin's surface, helping to retain moisture and enhance barrier function. The polysaccharides provide humectant properties, drawing water to the skin, while antioxidants combat oxidative stress from environmental factors. Commonly found in moisturizers, serums, and masks, it contributes to smoother texture without greasiness. Its natural origin makes it suitable for various formulations targeting hydration and protection.
