title: Enriched Facial Skin Serum Formulation Using Nanogold and Oligochitosan Particles: Optimization by Box Behnken Design
abstract: Facial skin continuously exposed to oxidative stress can accelerate the skin aging process, and the effects of aging can be prevented using cosmetic products, such as facial serums containing antioxidants. Consequently, nanogold is widely used as a modern cosmetic ingredient because of it antioxidant properties. The addition of oligochitosan minimizes the use of synthetic antibacterials in serum preparations. Therefore, this study aimed to formulate, optimize, and characterize an anti-aging seru
