The remarkable advancement of social media technologies as a promotional platform has transformed influencers into key agents in shaping consumer behaviour, particularly noticeable among Millennials and Generation Z. In Indonesia, the rise of local cosmetic brands has been closely tied to the effectiveness of influencer marketing strategies in building consumer trust and engagement. This research seeks to examine how trust, engagement, and credibility of social media influencers affect the purchase decisions of Millennial consumers toward local cosmetic products in Banjarmasin. A quantitative research approach was employed using a non-probability sampling technique, specifically purposive sampling.
