Natural Moisturizing Materials and their Nanoparticles

Moisturizing is one of the most important and fundamental functions in the skincare process, and the moisturizing effects of hyaluronic acid, ceramide, and collagen have been widely validated in the skincare field. Hyaluronic acid has excellent water-retention properties, ceramide strengthens the epidermal barrier to reduce water loss, and collagen enhances skin hydration and elasticity. This article combines the development of nanotechnology, first constructing a nanostructure of hyaluronic acid through emulsification, polyelectrolyte complex formation, and gel formation. To further optimize their synergistic effects and delivery efficiency, this study employs the film dispersion method to prepare ceramide-collagen liposomes, encapsulating the active ingredients within the lipid bilayer, significantly improving stability and bioavailability. Meanwhile, the study also explores hyaluronic acid-collagen electrospinning technology to enhance long-lasting moisturization and structural integrity. These innovative technologies not only amplify the inherent moisturizing advantages of the core ingredients but also provide new ideas for the development of multifunctional skincare systems. This research offers a forward-looking strategy for designing next-generation skincare formulations.
