The Rise of 'Underconsumption Core' and What It Reflects About Modern Buyers

Where the Term Came From

In mid-2024, a new term began circulating heavily on TikTok and other social platforms: underconsumption core. Unlike the aspirational haul videos that had defined social media shopping culture for years — where creators unbox piles of new clothing, beauty products, or home goods — underconsumption core content looks radically different. Creators show nearly-empty refrigerators stocked with staples, small wardrobes of well-worn basics, and products used down to the last drop before replacement.

The "core" suffix signals that this is being framed as an aesthetic identity, much like "cottagecore" or "darkcore." But unlike purely visual aesthetics, underconsumption core carries an implicit critique: it positions excessive buying as something to be questioned rather than celebrated. To understand why it resonated so quickly, you have to look at what preceded it — and what was happening economically.

The Economic and Cultural Backdrop

Consumer sentiment in the U.S. shifted considerably following the inflation surge that began in 2021 and persisted well into subsequent years. Everyday goods — groceries, gas, housing — became meaningfully more expensive, and many households recalibrated what they considered essential. Inflation reshaped purchasing priorities in ways that went beyond cutting back; it changed how people thought about value itself.

At the same time, a growing body of research in behavioral economics and psychology has found weak links between material acquisition and lasting satisfaction. The hedonic treadmill — the tendency for people to return to a baseline level of happiness regardless of new purchases — is well-documented. As this research filtered into mainstream awareness, it gave intellectual backing to what many consumers were already feeling: that buying more wasn't delivering what it promised.

“The evidence consistently shows that once basic needs are met, additional material consumption contributes little to well-being — and often detracts from it through the stress of acquisition, maintenance, and disposal.”

— Tim Kasser, Psychologist and researcher on materialism and well-being, Knox College

The result was a cultural moment ripe for a counter-narrative. Underconsumption core filled that space, offering both a visual aesthetic and a value framework that felt authentic to a generation skeptical of advertising.

What It Actually Looks Like in Practice

For many participants, underconsumption core isn't a strict ideology — it's a loose set of behaviors that express a shift in priorities. Common expressions include:

• Using products completely before buying replacements
• Maintaining a small, functional wardrobe rather than chasing seasonal trends
• Repairing or repurposing items instead of discarding them
• Resisting the urge to buy things simply because they appear on a feed or in a promotion

This intersects with the growing mainstream resale market, where buying used goods has lost its stigma and become a deliberate choice for many shoppers. It also connects to what researchers describe as conscious consumption in everyday practice — the gap between stated values and actual purchasing behavior narrowing for a meaningful share of consumers.

Why It Matters Beyond the Aesthetic

Underconsumption core is worth examining not just as a social media category but as a signal of underlying behavioral change. Americans are buying less and returning more, and this trend didn't emerge in a vacuum. It reflects a convergence of financial caution, environmental awareness, and psychological reappraisal of what ownership actually provides.

It's also worth noting the inherent tension the movement navigates. Even content about buying less is produced and consumed on platforms built around engagement and commerce. And as with any trend, there's a risk of it becoming performative — or being co-opted by marketing. Impulse buying hasn't disappeared, and the same psychological mechanisms that drive unnecessary purchases remain active. Understanding these contradictions honestly is part of what makes the movement genuinely interesting as a cultural moment.

Whether underconsumption core endures as a lasting behavioral shift or fades like other social media cycles remains an open question. Not all consumer trends stick, but the economic and psychological pressures driving this one suggest it reflects something more durable than a passing aesthetic. For readers interested in building more deliberate purchasing habits, developing savvier buying habits starts with understanding why our impulses toward consumption exist in the first place.
