Impact of marine collagen on nanocosmetics: A comprehensive review

Collagen, a fundamental protein in the extracellular matrix, plays a pivotal role in maintaining skin health, elasticity, and overall appearance. In recent years, marine-derived collagen has gained significant attention due to its unique properties, sustainable sourcing, and potential applications in pharmaceuticals, drug delivery systems, food industry, biomedical and cosmetic industry. Marine collagen, derived from marine organisms, has emerged as a valuable ingredient in cosmetic formulations due to its superior biocompatibility, biodegradability, and high tensile strength. In nanocosmetics, marine collagen is often incorporated into nanoparticles to improve its delivery and efficacy. The incorporation of marine collagen in nanocosmetics not only leverages its anti-aging benefits but also enhances the stability and bioavailability of other active ingredients in the formulation. This review summarizes various properties, extraction methods, processing, purification, applications and regulatory requirements of marine collagen. Additionally, potential benefits challenges, and future directions of marine collagen nanoparticles discussed in this article would be beneficial for researchers for developing newer formulations.
