Objective: The purpose of this study is to make facial serum from astaxanthin-beta carotene nanoemulsion as an antioxidant. Methods: Nanoemulsions were prepared using Spontaneous Nanoemulsion (SNE) method with a ratio of 1:8:1 for (Sunflower oil): surfactant (Kolliphor® RH40): and co-surfactant (PEG 400). Physical nanoemulsion characterization includes globule size, polydispersity index, zeta potential, visual appearance, pH and entrapment efficiency test. The best results from nanoemulsion were then combined into serum preparations which were then tested for evaluation of the preparations, including organoleptic, homogeneity, viscosity, pH, adhesion and stability test (cycling test). Results: The results showed that the nanoemulsion of astaxanthin and beta-carotene combination that had been developed had a globule size of |
