This serum focuses on the skin's natural flora, promoting the growth of skin-beautifying bacteria (Staphylococcus epidermidis) with increased use. It enhances skin's natural regenerative and defense abilities, weakened by aging, leading to self-sustaining skin. Formulated with two active ingredients (niacinamide and glycyrrhizic acid), it also provides effective anti-aging care*. This all-in-one serum (toner, emulsion, cream, and serum) serves four purposes in one for both men and women. It also contains vitamin C derivatives and Centella asiatica extract, a CICA ingredient. It's free of eight additives and has undergone third-party patch testing. A few drops are enough to spread evenly over the entire face, and the main ingredient, beauty ingredients, enhance the concentration of ingredients for long-lasting moisture. After use, you'll be enveloped in the gentle, natural lavender scent. Even with twice-daily use, it lasts for about a month, eliminating the need for other skincare or anti-aging products, making it cost-effective. It's unisex, so you can enjoy a smart skincare routine with just one bottle at home. Its convenient size makes it ideal for travel or business trips. *Age-appropriate care
