Abstract: The skin has important functions and requires special care to combat signs of skin aging, a process of biological oxidation that reduces antioxidant defenses. In response to advances in the aesthetics industry and the growing demand for less aggressive cosmetic products, the industry has started to develop multifunctional cosmetics, such as serums, a type of cosmetic that has a moisturizing action and can be combined with natural active ingredients, such as Hibiscus sabdariffa L. Popularly known as “red hibiscus” or simply “hibiscus”, this plant has antioxidant properties in its compositions, ideal for delivery in the form of serums. The present study aimed to develop and evaluate the quality of serums contained in the dry extract of H. sabdariffa. For this purpose, a base formula without extract and two formulas containing H. sabdariffa extract were designed, manipulated and subjected to centrifugation resistance tests, determination of pH, electrical conductivity, density, spreadability and preliminary stability study, according to the ANVISA Guide for Studies on Stability of Cosmetic Products. In addition, the antioxidant activity by the DPPH radical scavenging method was performed with the hibiscus extract. As a result, the antioxidant activity of the extract obtained an IC50 of 522.40 µg/mL. The samples withstood centrifugation. After being subjected to the preliminary stability study and quality control tests, the samples had pH ranging from 6.53 to 4.26; conductivity with values between 181.3 and 103.7 mV; and density between 1.01 and 1.02 g/mL. Not referring to spreadability, it was found that the base had greater spreadability than the formulas with hibiscus extract. Furthermore, the spreadability of the samples subjected to the freezing and thawing cycles had reduced spreadability. Regarding viscosity, the base was the least viscous formulation, corroborating the spreadability data. The manipulated formulas had consequences, with some changes in the results of the analyses performed before and after the preliminary stability study, highlighting its potential as a product for the cosmetics industry.
