When combined with carrageenan, it enhances moisture retention and stabilizes encapsulated actives. This blend protects vitamins from environmental degradation and prolongs their release, allowing nutrients to penetrate deeper into the skin. ## **Physical Properties of Hydrogel Microspheres** The study’s initial findings are promising. The hydrogel microspheres are smooth, spherical, pore-free, and measure between 10-20 μm. These characteristics make them ideal for transdermal delivery. Moreover, using vitamins A, C, and E as active ingredients, the microspheres achieved a high loading capacity of 70% to 97%. This minimizes the loss of active compounds during the loading process. ## **Stability and Vitamin Release** Additionally, the microspheres also improved vitamin stability and availability in the skin. Their high-swelling ratio, ranging from 1300% to 1500%, allowed effective controlled release within the first six hours, with a tendency for continued delivery over time. The image illustrates the swelling ratio (SR) of five microsphere blends, measured after varying soaking times in a pH 5.0 buffer at 34°C. The CS-g-PCL(MSA):CG 50:50 demonstrates the highest swelling.

This finding is essential for ensuring the biocompatibility of these carriers. ## **Superior Performance Compared to Traditional Methods** Furthermore, hydrogel microspheres demonstrated superior transdermal permeation enhancement compared to standard oil-in-water emulsion creams. Their antibacterial and antioxidant properties, along with excellent biocompatibility, make them particularly appealing for cosmetic applications. These innovative formulations also eliminate preservatives and parabens, promoting safer, more natural skincare solutions. In summary, hydrogel microspheres made from chitosan and carrageenan hold significant promise for the cosmetics industry. Their stability and prolonged vitamin release make them valuable not only for skincare but also for potential applications in biomedicine. As this research advances, the benefits of these microspheres may extend across multiple fields. It provides an innovative solution for targeted nutrient delivery.
