Marine-derived cosmetics: A promising frontier in sustainable skincare


Marine-derived cosmetics: A promising frontier in sustainable skincare

The cosmetics industry, driven by growing consumer demand for sustainable and health-conscious products, is turning to the vast, untapped resources of the ocean for innovation.


A recent scientific review, Marine Cosmetics and the Blue Bioeconomy: From Sourcing to Success Stories, explores how marine-derived compounds are revolutionising skincare, hair care, oral hygiene, and cosmeceuticals. This review not only highlights the bioactive potential of marine resources but also delves into the challenges and opportunities within the industry, offering a blueprint for sustainable development in cosmetics.


Unlocking the ocean's potential


Marine organisms, including algae, invertebrates, and microorganisms, have evolved to produce bioactive compounds that are uniquely suited for cosmetic applications. These compounds exhibit a broad spectrum of beneficial properties, including antioxidant, anti-inflammatory, anti-wrinkle, and anti-acne effects. Skincare products enriched with marine ingredients, such as seaweed extracts and marine collagen, are increasingly popular for their ability to rejuvenate and protect the skin.


One of the key benefits of sourcing ingredients from the ocean is sustainability. Unlike terrestrial resources, which often compete with agriculture and face limitations in scalability, marine resources provide an alternative that aligns with global goals for environmental conservation. However, responsibly harnessing this potential requires careful management to prevent overexploitation and ensure ecosystem health.


Applications across cosmetic sectors


The review emphasises the versatility of marine-derived ingredients:


  • Skincare: Marine polysaccharides and proteins are celebrated for their moisturising, anti-ageing, and protective properties.

  • Sunscreen: Marine compounds like mycosporine-like amino acids (MAAs) offer natural UV protection, reducing reliance on chemical sunscreens.

  • Hair Care: Algal extracts provide strengthening and nourishing benefits for hair health.

  • Oral Care: Antibacterial and remineralisation properties of marine bioactives are finding applications in toothpaste and mouthwash formulations.

  • Cosmeceuticals: Functional ingredients with therapeutic benefits are being integrated into advanced skincare and wellness products.


Challenges in scaling marine innovation


While the ocean provides a promising source of novel ingredients, the journey from discovery to commercialisation is fraught with challenges. Extracting, purifying, and scaling the production of marine bioactives often require significant technological innovation. Biorefineries and advanced systems biology techniques are emerging as critical tools for making these processes economically viable and environmentally friendly.

Safety remains a paramount concern. The cosmetics industry must navigate complex regulatory frameworks to ensure that marine-derived compounds meet stringent safety standards. Additionally, the potential for allergenic or toxic effects must be thoroughly investigated to maintain consumer trust.


Success stories: Bridging science and sustainability


Three case studies featured in the review illustrate the potential of marine resources in transforming the cosmetics industry:


  • Iceland's Macroalgal Skincare: Icelandic companies are harnessing local algae species to create eco-friendly skincare products, reducing their reliance on imported materials while promoting sustainability.

  • Microalgal Cosmetics in Italy: A spin-off company has developed a range of innovative products based on microalgal compounds, showcasing how biotechnology can unlock marine potential.

  • Marine Proteins for Cosmeceuticals: Functional proteins derived from marine sources are being used in targeted treatments for skin health and rejuvenation.


These examples highlight how collaboration between scientific research and industry can lead to sustainable, high-quality products that cater to modern consumer demands.


A blueprint for the future


The integration of marine resources into the cosmetics industry is more than a passing trend. It represents a critical shift towards a blue bioeconomy, aligning with the principles of sustainability and innovation. By fostering interdisciplinary collaboration and investing in research and development, the cosmetics sector can lead the charge in creating products that are not only effective but also environmentally responsible.


Moreover, the focus on marine-derived ingredients resonates with broader sustainability goals, such as those outlined in the United Nations Sustainable Development Goals (SDGs). From supporting life below water (SDG 14) to promoting responsible consumption and production (SDG 12), marine cosmetics have the potential to address multiple global challenges.
