Inflammation is a common biological response in the body to harmful stimuli, often leading to skin conditions like dermatitis, inflammatory acne, and rosacea. These conditions affect millions worldwide, prompting the cosmetics industry to seek solutions for both health and aesthetic concerns.
Addressing the need for effective, natural, and sustainable ingredients, a recent study explored the potential of marine cyanobacteria in combating skin inflammation. Conducted by Janaina Morone from CIIMAR’s Blue Biotechnology, Environment, and Health research group, the research focused on the carotenoid profile of cyanobacteria.
The study, published in “Algal Research,” revealed that cyanobacteria extracts rich in carotenoids can reduce the production of inflammatory mediators, making them promising agents for treating inflammatory skin conditions. These extracts have the ability to calm existing inflammation by neutralizing free radicals and inhibiting enzymes responsible for producing inflammatory mediators.
Notably, the cyanobacteria strains from the Cape Verde archipelago analyzed in the study exhibit a unique carotenoid profile dominated by zeaxanthin and β-carotene. These compounds not only alleviate inflammation but also prevent its onset by inhibiting nitric oxide production, a key mediator in the inflammatory process.
Furthermore, the study highlighted the safety and sustainability of these cyanobacterial extracts, making them desirable for cosmetic and pharmaceutical industries. Their natural, vegan, and eco-friendly attributes align with the increasing consumer demand for ethical and effective skincare products.
Dispelling misconceptions about cyanobacterial toxicity, the study confirmed that the strains used are non-toxic and safe for various applications. These strains are now part of CIIMAR’s cyanobacteria and microalgae culture collection, paving the way for future research on their mechanisms and formulations.
Looking ahead, researchers emphasize the potential of cyanobacteria as a valuable bio-resource for producing innovative and sustainable products. They envision further studies to explore the diverse applications of cyanobacterial compounds, including their stability in formulations and broader therapeutic uses.
In conclusion, marine biotechnology offers a promising solution to meet the evolving needs of consumers for natural, effective, and sustainable skincare products. The future of skincare lies in harnessing the potential of marine resources like cyanobacteria to develop innovative solutions for health and well-being.
