The Mediterranean Sea is a natural enclave of the Region of Murcia with the largest salt lagoon in the world with a great wealth of seaweed. They are classified by the color they present, the most used being sea lettuce (green), fucus and laminaria (brown) and gelidios (red). The enormous benefits that sea algae provide us derive directly from their properties, since a very important concentration of active elements is achieved. In addition to organic iodine, it is rich in essential trace elements such as Mn, Sn, Cl, Se, U, Mo, Ag, Br, Cu, F, Au, Co; vitamins A, B, C, D and E; alginic acid and alginates, mineral salts, proteins, carotenoids and halogenated phenols among others. The great wealth of minerals that algae provide us favors cell stimulation, managing to delay the appearance of wrinkles, purifying, and eliminating toxins, creating a perfect skin balance.
