The beautiful marine landscape reflects the enormous richness of marine biodiversity. The marine environment is indeed a rich source of structurally diverse bioactive compounds with unique potential. This is due to the physicochemical nature of the marine environment, where conditions of high salinity, pressure, low and high temperatures, and lack of light can lead to the biosynthesis of highly functional and unusual molecules in marine organisms. Antioxidant compounds play a key role in maintaining cellular redox homeostasis and the survival of marine organisms that are constantly exposed to environmental stress and change. Seaweeds, microalgae, sponges, corals, tunicates, and other marine organisms produce numerous molecules that can alleviate oxidative stress-related diseases, photoaging, and skin aging. For example, marine carotenoids are known to have beneficial physiological functions as anti-inflammatory and cardioprotective agents. However, the potential of the most exciting marine bioactive molecules remains largely untapped.
