Scientifically proven results and triple filtered, our MW Macroalgae Extract™ delivers powerful moisturizing and rejuvenating benefits.
Seaweed has the superpower to keep natural systems balanced and nourished. Our marine botanical formulation—MW Macroalgae Extract™—is the star ingredient in each of our creams, serums, and soap bars. The unique tincture is crafted from a blend of three seaweed species indigenous to Zanzibar, which we are the first and only company to bring these varieties to market.
Clinical Results
Key Findings
Mwani Zanzibar began our journey researching indigenous seaweed varieties, resulting in the identification of several species with notable health benefits—packed with phytochemicals, rich in amino acids, and saturated with vitamins and minerals. To enable commercial use, we registered these varieties on the international ingredient database (INCI), and patented their extraction. We are the first and only company to bring these varieties to market. Together with other African botanicals and unrefined oils, we craft our skincare collection for our global customers.
From Sea to Skincare
From Source to Product
Seaweeds help rebuild collagen. Our seaweed—based extract is clinically proven to affect not only the metabolism of the skin’s top layer (epidermis), but also penetrate the middle layer (dermis) too. Learn how we transform it into our skincare products.
