What Is Underconsumption Core and How to Actually Do It

Underconsumption core is a TikTok trend where people show off how little they buy: the one water bottle they've had for years, the lip balm scraped down to the end, the couch with a blanket hiding a stain. It took off in summer 2024 as a reaction to haul culture, and the point is simple. Use what you already own until it's actually used up, and treat that as normal rather than sad.

Where underconsumption core came from

For years, a huge share of lifestyle content on TikTok and YouTube was hauls: unboxing ten things from one order, restocking a pantry with matching containers, "everything I bought this month." Underconsumption core flipped the format. Instead of the new stuff, creators filmed the old stuff. A phone case that's cracked but still works. Five T-shirts on rotation. A single bottle of shampoo rather than a shower shelf full of half-used ones.

It didn't appear out of nowhere. It grew out of deinfluencing, the 2023 trend where creators told viewers what not to buy, and it overlaps with older ideas like minimalism and frugal living. The difference is the vibe. Minimalism tends to look curated: white walls, three perfect objects. Underconsumption core looks lived-in. Mismatched mugs, worn sneakers, a drawer of chargers. Nothing has been bought to make the shot look nice, and that's the joke and the message at the same time.

If you're curious about the trend that came before it, there's a full breakdown of deinfluencing and how it works.

Why it caught on

A few things lined up at once.

Prices. After the post-pandemic inflation spike, groceries, rent, and everyday goods cost noticeably more for a lot of Gen Z and millennial viewers. Watching someone buy 40 things in one video started to feel out of touch, and watching someone make a $4 bottle of lotion last six months felt relatable.

Haul fatigue. People got tired of the treadmill. You buy the viral thing, it turns out to be fine, and next week there's a new viral thing. Seeing creators step off that loop was a relief.

Sustainability. Using things longer means less waste. A lot of viewers already cared about fast fashion and overproduction, and underconsumption core gave them a way to talk about it without a lecture.

It's a little bit funny. Half the appeal is the humor of admitting your home doesn't look like an ad. Showing the hair tie you've used since 2021 is a small act of honesty that people enjoy.

The trap: performing underconsumption

Like every aesthetic trend, this one picked up some contradictions. Some creators who clearly buy a lot posted carefully staged "underconsumption" videos, which critics called poverty cosplay. Others started buying things that looked appropriately worn or simple, which kind of defeats the purpose.

The trend only helps you if it changes what leaves your account. If you find yourself buying a nicer reusable bottle so your underconsumption content looks better, you're back in the haul loop with a different filter on it. The real version is boring and doesn't need a camera.

How to actually do underconsumption core

Here's what it looks like in practice, without the aesthetic.

Use it up before you replace it

Pick a category where you tend to stockpile, like skincare, candles, notebooks, or snacks, and finish what's open before opening anything new. The beauty community calls this "project pan," from the idea of using a product until you hit the bottom of the pan. It works for almost anything. Most people are surprised how long their existing supply lasts once they stop topping it up.

Rewear on purpose

Outfit repeating is the heart of the trend. A useful exercise: for the next month, only wear what's already in your closet and notice which pieces you reach for. The ones you never touch tell you a lot about what kind of purchases tend to disappoint you. That's more useful than any style guide.

Repair before you replace

Sew the button back on. Glue the sole. Replace the cheap cable instead of the whole device. Take the sneakers to a cobbler. Repair has gotten easier thanks to tutorials, and fixing something gives you the same small satisfaction as buying something, without the bill.

Shop your own home first

Before buying anything, check whether you already own something that does the job. A storage box can be a shoebox. A "gym bag" can be any bag. This one habit catches a lot of purchases that were really about the feeling of a fresh start.

Make secondhand the default

When you do need something, look at thrift stores, Facebook Marketplace, Depop, or a local Buy Nothing group first. It's not about never buying. It's about buying the thing you need rather than the newest version of it.

Slow down the wants

The hardest part isn't using what you have. It's the constant stream of new wants from your feed. A waiting period helps a lot here: write the thing down with its price and the date, and come back after a few days. There's a whole guide on how long to wait before buying something if you want a system for it.

Some people find it easier to turn the waiting into something visible. Cake, an iOS app in development, is built around this idea: you put a want on a "cake" sized by its price, at $5 a slice, and fill the slices with good habits and purchases you skipped while the money builds in a virtual jar. When the cake is full you decide with a clear head whether you still want it.

What underconsumption core is not

It isn't deprivation. You don't have to stop buying things you enjoy, and you don't have to make your home look shabby to prove a point. It also isn't a moral contest. Some people underconsume because they want to, and some because money is tight, and neither group needs to be judged.

The healthiest way to think about it: buy fewer things, use them more, and let the stuff you own earn its spot. If you spend less along the way, great. If you discover you love one expensive coat you wear every winter day, that counts too.

A simple way to start this week

If you want to try it without overthinking:

• Pick one category to "pan" this month and don't buy any more of it until something runs out.
• Wear only clothes you already own for 30 days.
• Fix one thing you were going to replace.
• Keep a list of everything you want to buy, with prices, and don't buy any of it for a week.

At the end, look at the list. Usually a big chunk of it no longer seems important, and that's the trend working the way it's supposed to.

Common questions

Is underconsumption core the same as minimalism?

They overlap, but they aren't the same. Minimalism often focuses on owning very few, carefully chosen things, which can still involve buying new items to get the look right. Underconsumption core is about using what you already have, even if it's mismatched, worn, or not especially pretty. The goal is to buy less, not to look minimal.

Do I have to stop buying new things completely?

No. Underconsumption core is about buying when you need something or truly want it, not on autopilot. Replacing a broken item, buying a gift, or getting something you've wanted for months all fit fine. The idea is to cut the automatic purchases, not every purchase.

How is underconsumption core different from a no-spend challenge?

A no-spend challenge sets strict rules for a fixed period, like no nonessential spending for a month. Underconsumption core is more of a lifestyle and mindset with no end date. Many people use a short challenge to kick-start the habits, then keep the underconsumption mindset afterward.

Is underconsumption core just a trend that will fade?

The hashtag might fade, as most TikTok trends do, but the habits behind it are old: use things up, repair, rewear, buy secondhand. Those have been around for generations under different names. What the trend did was make them feel normal and a bit fun for people who grew up surrounded by haul content.
