      Abstract
      Sinar UV menyebabkan kerusakan kolagen dan dehidrasi pada kulit yang dapat memicu penuaan dini. Efek penuaan dapat dicegah dengan menggunakan kosmetik, misalnya serum wajah yang mengandung antioksidan. Nanoemas banyak digunakan sebagai bahan kosmetik modern karena dapat berperan sebagai antioksidan. Tambahan oligokitosan dapat meminimumkan penggunaan antibakteri sintetis pada serum. Penelitian ini menggunakan metodologi respons permukaan desain Box Behnken, dengan tujuan mengoptimisasi serum perawatan kulit wajah berbasis nanoemas dan oligokitosan. Formula optimum ditentukan berdasarkan parameter sifat fisik pH dan viskositas, kemudian dilakukan uji stabilitas, pengukuran aktivitas antioksidan, dan karakterisasi dengan mikroskop elektron transmisi (TEM). Kombinasi konsentrasi oligokitosan dan asam hialuronat optimum berturut-turut adalah 2,5% dan 1%; 5% dan 0,6%; 0% dan 0,6%, serta 2,5% dan 0,2%. Keempat formula tersebut memiliki nilai pH pada rentang 4,64–5,02 dan nilai viskositasnya pada rentang 15–1320 cP. Kapasitas antioksidan keempat formula ini lemah serta analisis TEM menunjukkan ukuran sediaan pada rentang 3−123 nm.
       
      UV rays cause collagen damage and dehydration in the skin, triggering premature aging. The effects of aging can be prevented using cosmetics, such as facial serum containing antioxidants. Nanogold is widely used as an ingredient in modern cosmetics because it can act as an antioxidant. The addition of oligochitosan can minimize the use of synthetic antibacterials in serum. This research uses the Box Behnken design surface response methodology to optimize facial skin care serums based on nanogold and oligochitosan. The optimum formula was determined based on the physical property parameters pH and viscosity, then stability tests were carried out, antioxidant activity measurements were carried out, and characterization was carried out using a transmission electron microscope (TEM). The optimum concentration combination of oligochitosan and hyaluronic acid is 2.5% and 1%, respectively; 5% and 0.6%; 0% and 0.6%, and 2.5% and 0.2%. These four formulas have pH values in the range of 4.64–5.02 and viscosity values in the range of 15–1320 cP. The antioxidant capacity of these four formulas is weak, and TEM analysis shows the size of the preparations in the range of 3−123 nm.
