The objective of this research is to identify the effects of product development and customer satisfaction by studying the consumers of Fresh Care Smash. This research is important to conduct because consumers are currently more selective in choosing products based on innovation, packaging, content, and usage experience. Without product development that suits market needs, customer loyalty may decline. The data of this quantitative study was harvested from questionnaires regarding product quality, variance, convenience, style, and design as well as consumer’s expectation fulfilment distributed to 100 respondents selected via purposive sampling technique. The instrument has been tested for its validity and reliability, and the acquired data has been examined for their normality, heteroscedasticity, and linearity, while coefficient of determination and t-test were also performed. All of the statistical processes were performed using SPSS version 30.0.0. This study finds that product development significantly influences consumer satisfaction and that indicators of product development such as product quality, variance, style, and design also have positive and significant influences on consumer satisfaction. Product quality, product variety, and well-developed product styles and designs can increase customer satisfaction levels so that consumer loyalty to a product can be maintained properly.The objective of this research is to identify the effects of product development and customer satisfaction by studying the consumers of Fresh Care Smash.
