Marine algae are a very popular source of biological activities and are used in numerous formulations targeting everything from anti-aging to slimming. However, sustainability and sourcing are often in question. Aquaculture has provided very reliable sources of marine organisms, but can often not go any further than Mother Nature has already invented. In order to add diversity to a natural source, we sought to marry a macroalgae with the yeast ferment of a microalgae and test the resulting brew for biological activity. Such marriage, has in our hands, shown solid anti-aging capabilities, and we are only now beginning to uncover the diversity of activities and compounds we are putting to the service of Skin Care with this technology.
