Insights into Bioactive Peptides in Cosmetics

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