Research Summary
Bioactive peptides have gained significant attention in the cosmetic industry due to their potential in enhancing skin health and beauty. These small protein fragments exhibit various biological activities, such as antioxidant, anti-aging, anti-inflammatory, and antimicrobial properties, making them ideal ingredients for cosmetic formulations. Bioactive peptides are classified into four categories: signal, carrier, neurotransmitter-inhibitory, and enzyme-inhibitory peptides.
This review provides insight into the application of bioactive peptides in cosmetics and their mechanisms of action, such as downregulating pro-inflammatory cytokines, scavenging radicals, and inhibiting collagen, tyrosinase, and elastase synthesis. Abundant natural origins, such as animals, plants, and marine sources, have been identified as primary sources for extracting cosmetic peptides through various techniques, including enzymatic hydrolysis, ultrafiltration, fermentation, and high-performance liquid chromatography.
Furthermore, the safety and regulatory aspects of using peptides in cosmetics are examined, addressing potential allergic reactions and regulatory guidelines. The challenges of peptides in cosmetics are also discussed, emphasizing the need for further research to fully harness their potential in enhancing skin health.
Overall, this review provides a comprehensive understanding of the application of peptides in cosmetics, highlighting their transformative role in the development of innovative and effective skincare products.
