TikTok's "Underconsumption Core" trend is growing in popularity among young adults, promoting minimalist living, sustainability, and repurposing items instead of purchasing new ones. The movement has emerged as a response to rising costs of living and constant advertising exposure, leading to consumer fatigue. It encourages individuals to buy less, buy better, and live sustainably by reusing and repurposing items, valuing quality over quantity, and prioritizing authenticity from content creators.
