<![CDATA[External aging factors such as UV exposure, pollution, and lifestyle choices contribute to skin aging, resulting in deep wrinkles, fine lines, and rough skin, which can lower self-confidence. Plant extracts have been widely studied for their antiaging potential, while Salmon DNA has shown promise in stimulating collagen production. This study explores the formulation of a serum combining Centella asiatica, Curcuma longa, Aloe vera, Rosa centifolia, and Salmon DNA for its antiaging effects on injured human fibroblast cells. The serum was formulated using extracts from C. asiatica, C. longa, A. vera, R. centifolia, and Salmon DNA. Antioxidant activity was evaluated with the DPPH method, cytotoxicity using the WST-8 assay, and gene expression through qRT-PCR for COL1A1, TGF-β1, HYAL-1, and FGF-2. The serum exhibited weak antioxidant activity (IC50 = 373.33 µg/ml) and reduced cell viability at high concentrations. Gene expression analysis revealed increased expression of COL1A1, TGF-β1, and FGF-2, along with reduced HYAL-1 expression in injured BJ cells. The formulated serum shows potential as an antiaging agent, promoting collagen production and reducing hyaluronidase activity.]]>
