Revealing the utilization of microalgae in cosmetics: insights from a comprehensive scientometric analysis over the last two decades

Utilizing microalgae in cosmetics has become a rapidly expanding sector, valued for its

sustainability and potential for innovation. The current article provides a detailed scientometric analysis

of microalgal research within the cosmetics industry over the last two decades. Our findings reveal a

notable annual growth rate of 13% in research activity, underscoring the increasing global interest and

advancements in this field. International collaboration plays a significant role, with nearly 30% of research

efforts involving partnerships across countries, showcasing a strong global network. The interdisciplinary

nature of the research is evidenced by its presence in leading journals such as Marine Drugs, Science of the

Total Environment, and Algal Research. China leads the way with (538) publications, followed by India

(234), Spain (174), and Portugal (173). Other major contributors include Brazil, the USA, South Korea,

and Italy, further highlighting the widespread international focus on microalgae in cosmetics. This global

involvement reflects the importance of collaboration and interdisciplinary approaches in advancing the

field. Our study offers key insights into the current trends, major contributors, and emerging topics in the

use of microalgae for cosmetics, providing a solid foundation for future research and innovation in the

development of sustainable cosmetic products.
