Currently, live streamed shopping has emerged as a potentially lucrative and rapidly expanding market platform. There has only been a small amount of research done to investigate the factors that consumers cite as their primary motivation for using live-streaming as a platform. As a result, the purpose of this research is to determine what kinds of influences can have an effect on the purchasing of cosmetic products by online shoppers in Malaysia, with the end goal of closing the research gap that has been identified. Both the Gratification and Uses Theory (UGT), also known as the theory of entertainment gratification and the theory of informativeness gratification, as well as the source credibility theory, also known as the theory of trustworthiness, attractiveness, and expertise, are utilised in order to investigate the relationship between the theory of planned behaviour and the intention to make a purchase. 373 samples was collected using convenience sampling survey. In the context of live-stream cosmetics, research on the relationship between purchase intention and purchase behaviour is conducted with the assistance of the theory of planned behaviour. When compared to the practise of adopting just one theory, the adoption of all three theories can produce a result that is both more specific and more comprehensive. Aside from that, this research should provide a better understanding to sellers of the motivation factors that result in consumers completing a purchase, which gives retailers the opportunity to create their own business strategies to complete a sale. In addition to that, this research should provide a better understanding to sellers of the motivation factors that result in consumers completing a purchase. The study is aimed at internet users, specifically those who have experience watching live cosmetics-related streams on social media and have an interest in or knowledge of the cosmetics industry. In addition, the self-made questionnaire will be shared on social media platforms such as Facebook, Instagram, WhatsApp, and WeChat. The information that we have gathered will be analysed using models of linear regression in SPSS. In addition to that, linearity tests were carried out in order to offer empirical support for the items that were developed. This research has the potential to further strengthen the validity of UGT, SCT, and TPB, all of which have the potential to become obsolete as more time passes. In addition to that, it may offer a fresh approach to running a business for retailers, particularly for online retailers operating as small businesses.
