Sustainable Development Goals (SDGs) and Seaweed: A Potential Solution for Aging Skin
Introduction
Seaweeds have gained attention for their numerous potential benefits, ranging from carbon storage and reducing methane emissions to producing biofuels and renewable plastics. They also have wound-healing properties and possible anti-aging effects. The seaweed farming industry is thriving, and researchers continue to explore their potential applications.
Study on Seaweed Extracts and Skin Aging
A recent study conducted by researchers at Flinders University in Adelaide investigated the effects of extracts from two brown seaweeds on skin aging. The study utilized lab experiments with human-like skin cells and found that the seaweed extracts inhibited reactions associated with skin aging and increased collagen levels, one of the proteins responsible for youthful skin.
Potential of Brown Seaweeds
The study focused on three brown seaweeds: Ecklonia radiata, Cystophora moniliformis, and Cystophora siliquosa. The extracts from the two Cystophora species stimulated collagen production in the lab-grown cell lines. However, the production of elastin, another structural protein in skin, was not affected.
Anti-Glycation Effects
The researchers also tested the seaweed extracts’ impact on protein glycation, a process associated with aging skin. The extracts from C. moniliformis and C. siliquosa inhibited glycation activity in the experiments. This is a promising finding, as previous attempts to target this pathway have shown limited effectiveness and undesirable side effects.
Future Research and Clinical Trials
While these preliminary findings are encouraging, further research is necessary to develop a safe and effective product. Randomized clinical trials would be required to rigorously test the benefits of seaweed extracts on skin aging and ensure their safety for human use. It is important to note that not all seaweed supplements have been as effective as initially hoped, and factors such as cultivation conditions and other dietary factors can influence their outcomes.
Considerations and Recommendations
Before seaweed extracts can be widely used for anti-aging purposes, purification and formulation processes need to be developed. The concentrations used in cell studies may not be suitable for human use. Additionally, taking supplements does not always result in noticeable benefits for the skin. Protecting the skin from sun damage, maintaining a healthy diet, and avoiding cigarettes are recommended approaches for maintaining healthy skin.
Conclusion
The study highlights the potential of brown seaweeds in combating skin aging. However, further research and clinical trials are necessary to validate these findings and develop safe and effective products. Seaweed’s potential contributions to sustainable development align with the Sustainable Development Goals (SDGs), particularly Goal 3: Good Health and Well-being.
