They wear their clothes multiple times, don’t upgrade their phones, and use bags for their entire lives.

This may sound familiar to you since many people do this in their everyday lives, but young influencers call it “underconsumption core.”

Generation Z uses social media and makes clips of their everyday lives – they claim it is a new trend.

Nicole from London has made a three-part series about her normal life for her 100,000 followers on TikTok.

In one clip, she shows how she uses trains and the London Underground instead of a car to travel to places for sustainability reasons and also because she “never learned to drive.”

Nicole from London said she uses public transport to be more sustainable, but also because she cannot drive herself.

Nicole also filmed herself reusing old jars for her leftover food, including oatmeal that had been soaked overnight, and repairing broken shoes instead of buying a new pair.

In a second video, Nicole, who makes clips about her vegan life, said she also reuses tote bags as gift bags for friends and family and invents meals based on what she has left in the fridge.

Emily Bourke, a 25-year-old designer from London, has also jumped on the trend and shared elements of her sustainable daily routine.

This included continuing to wear a pair of “battered” Adidas Superstars she had received when she was 15 and using a handbag that once belonged to her late grandmother.

Emily has also been using the same wallet her friend designed for her for three years, she uses her older sister’s bags that she inherited, and she still wears a gold Casino watch from ten years ago.

She captioned the video: “The essence of underconsumption I guess? Or just being attached to things lol.”

San Francisco millennial Kathryn Kellogg has a TikTok account called “Going Zero Waste,” where she often shows her followers how to live more sustainably.

In her clip about the essence of underuse, Kathryn said she still uses a six-year-old phone and admitted she has never dyed her hair, doesn’t get her nails done, and has never had Botox or fillers.

But Kathryn has received hate for her video before, captioning it: “I want to be clear because this post has received some negative comments on other platforms. If getting your nails, hair, etc. done makes you feel good – go for it!”

“These things don’t make me feel good, so I choose not to do them. I don’t like spending my time and money this way, and I often feel pressured by social media to do these things even though they don’t bring me joy.

“It seems like every two weeks there’s a new must-have beauty product or treatment being touted. I find this a financial burden and something that can be quite wasteful.”

Kathryn also said that 90 percent of her wardrobe is made up of used clothing, either from vintage or thrift stores.

Her clip received more than 11,000 likes and hundreds of comments from viewers.

One person wrote: “This is normal consumption. The overconsumption makes it look like underconsumption. Not a trend at all.”

Another wrote: “No Botox is just normal, not underuse.”

A third said: “I need more of this on my FYP because I’ve been impulsive lately!!!!!!”

Hope Zuckerbrow from Texas has more than a million followers on the platform and has decided to show her lifestyle.

The 26-year-old TikToker showed on her page that she still has her 10-year-old television, the original knife set from her college days and only one pair of tennis shoes because they are “so expensive now”.

She said she likes the trend of under-consumption, adding that instead of following trends to have a complex skincare routine, she only owns three products and has been using the same hair straightener since she was 17.

Hope said she preferred browsing Facebook Marketplace and thrift stores when furnishing her home rather than buying new furniture.

Her clip was viewed nearly 800,000 times and received hundreds of comments, with users thanking her for showing her normal lifestyle.

Leah Stapleton of Austin said she doesn’t understand the trend toward underconsumption

One wrote: “This is so rare to see on social media but it literally affects most people’s lives. Thank you for sharing.”

Another wrote: “My ultimate under-consumption is my Instyler, which I bought in the early 2000s and which I use to curl and straighten my hair.”

However, other content creators reacted sharply to these videos, admitting that they do not understand how a “normal” lifestyle can be a trend.

Leah Stapleton of Austin said on TikTok: “I don’t understand how literally just being a regular consumer can be a trend now?”

“I think it’s less about underconsumption and more about just being a normal person and not consuming too much.”

“If you’re a normal person, you can’t afford to have every color of every product in a makeup line.”
