Contains Recalca's signature ingredients, "Human Dental Pulp Cell-Conditioned Culture Medium" and "EGF (Synthetic Human Genetic Recombinant Oligopeptide-1)." As skin ages, it tends to become dry and develop thickened keratin. Moisturizing is essential for anti-aging care* to prevent skin problems such as irregular cell turnover. Sym Serum contains the moisturizing peptide ingredients "Human Dental Pulp Cell-Conditioned Culture Medium" and "EGF (Synthetic Human Genetic Recombinant Oligopeptide-1)." \ Point 1 / {A peptide ingredient that beautifully moisturizes skin that tends to dry out with age, improving its texture and firming it.} Stem cell-conditioned culture medium is a culture medium containing growth factors (including various peptide components) released when cells proliferate. Moisture not only provides moisture but also prevents rough skin, making it suitable for anti-aging care* to improve the texture and firmness of aging skin. \ Point 2 / {Bakuchiol, an ingredient that firmes and prevents rough skin} Bakuchiol (a legume-derived ingredient) has effects similar to retinol, which provides firmness and prevents rough skin. Sim Serum EX combines it with a retinol derivative (retinol palmitate) and calla lily flower extract, which are expected to have a synergistic effect with bakuchiol, to provide firmness, luster, and more effective prevention of rough skin caused by sebum than bakuchiol alone. \ Point 3 / {Contains radiance ingredients that brighten the skin by one tone} Radiance ingredients (phenylethyl resorcinol, fullerene, placenta extract, and umbilical cord extract) moisturize the skin, bringing brightness and luster. *Aging care = care appropriate to your age
