Seaweed’s Timeless Role in Skincare and Healing
Long before the hype around hyaluronic acid and collagen supplements, seaweed was cherished as a healing and skin cell-renewing agent for thousands of years across continents. Its use in skincare and medicine dates back to 2700 BCE in Ancient China for detoxification, and to the 1800s with the seaweed bath trend in Ireland and Scotland—known as thalassotherapy—which is still practiced today. Seaweed was also used for wounds healing, skin irritation, and postpartum care in Pacific Island and Indigenous cultures. Not to mention, since the 1st century AD during the Greco-Roman era, seaweed’s wound-healing properties were already documented in De Materia Medica.
We believe seaweed is more than just a super hydrating agent or soothing, calming aid—it’s like the skin of the ocean, made for human skin. Its compounds can help repair free radical damage, increase skin elasticity, and boost cellular rejuvenation.
Marine biologists and skincare researchers have been passionately drawn to this unparalleled bioactive star—bursting with polysaccharides, antioxidants, amino acids, and minerals. Numerous studies have shown that a direct connection between seaweed and the skin's microbiome. It helps regulate hydration, calms inflammation, provides antioxidant support, aids in barrier repair and anti-photoaging effects. Without a doubt, it is the most powerful, natural, ocean-born multitasker—an all-rounder in skin self-correction, self-defense, and renewal.
Through both controlled studies and countless testimonials from people who love our patented dry seaweed face mask, we’re seeing consistent results: healthy, glowing skin; reduced irritation; smoother texture; and visibly younger-looking skin. These results signal a reduction in oxidative stress and a supported, stronger inner repair cycle. Below, we’ve listed studies, research, and findings that help illustrate the powerful science behind seaweed skincare in its most natural form.
