Formulation And Evaluation of Facial Serum Containing Marigold and Rose Petal Extracts for Skin Regeneration and Collagen Production

This study aimed to formulate and evaluate a facial serum infused with Marigold (Tagetes erecta) and Rose (Rosa damascena) petal extracts to support skin regeneration and collagen production. Facial serums are concentrated emulsions, available in both water- and oil-based forms, containing significantly higher levels of active ingredients compared to traditional creams. Their small molecular structure allows for deep skin penetration, leading to faster and more noticeable improvements when incorporated into a regular skincare routine. The serum formulation takes advantage of the beneficial properties of marigold and rose extracts. Marigold contains lutein and zeaxanthin, which act as powerful antioxidants, protecting skin lipids from oxidative damage and reducing inflammation. Meanwhile, geraniol, a key compound in rose extract, exhibits antibacterial and antifungal activity against various pathogens, including E. coli and L. monocytogenes. Geraniol also possesses antioxidant and anti-inflammatory properties, helping to shield the skin from environmental aggressors while soothing irritation. To ensure product stability and effectiveness, the serum was developed with a combination of these botanical extracts, along with suitable emollients, preservatives, and stabilizers. Its physical properties, such as pH, viscosity, and spreadability, were optimized for ease of application and long-term stability. The results demonstrated a significant enhancement in collagen synthesis and skin cell regeneration, highlighting the potential of Marigold and Rose petal extracts in promoting healthy, youthful skin.
