From Egidio Siena great love for the sea and his experience in the field of cosmetics, the history of Guam began. Starting from the flower of seaweed, he developed a formulation also enriched with plant extracts and other natural ingredients until he obtained a mud which contained within itself all the properties of this precious GREEN GOLD. Thus, Guam Seaweed Muds were born, and have since been used and appreciated throughout the world.
