Outdoor activities that are inevitable can harm our facial skin, namely, the signs of premature aging. A gel peel-off mask (GPM) is a popular facial skin care treatment that can alleviate these symptoms. This study investigated the influence of polyvinyl alcohol (PVA) and microcrystalline bacterial cellulose (MCBC) concentrations on the gel peel-off mask's features, including organoleptic properties, pH, viscosity, adhesion power, and drying time. The GPM formula contains carboxymethyl cellulose, glycerol, propylene glycol, PVA, and MCBC. The PVA content ranges from 7 to 15%, and the MCBC concentration ranges from 0 to 15%. Furthermore, a test was conducted to assess the potency of MCBC as a delivery agent for the active substance (vitamin C) from the product to the facial skin during skincare application. The experiment revealed that the best product was obtained at a PVA concentration of 13% and MCBC of 10%. Applying a 10% MCBC component can provide active vitamin C to the facial skin with an 85% efficacy. Additionally, respondents completed a product acceptability test. Based on the findings, the usage of MCBC components in gel peel or mask products has the potential to be a commercially viable product. However, research on GPM formula optimization is required for optimal use.
