Examples of Underexploited Marine Organisms in Cosmeceutical Applications

A number of marine resources have been exploited for a long time. Examples include Fucus and Laminaria, from which gelling agents are extracted. Only a few hundred thousand marine species are currently known, representing a tiny fraction of the estimated total of between 700,000 and one million species. This opens up numerous possibilities for innovation in the cosmetics industry. In this study, we present various species that are currently under-exploited, but which could have applications in hydration and photoprotection, for example. Algae and microalgae are worthy of interest because they can be used for hydration and anti-ageing purposes. Collagen can be extracted from animal sources and used as a substitute for collagen of bovine origin. From a marketing perspective, it is possible to market it as 'marine collagen'. However, it is imperative to emphasize the significance of ensuring the sustainability of the resource. In accordance with this imperative, algae that are capable of being cultivated are distinguished by their enhanced qualities.
