If you’re fluent in TikTok, terms like Gen Z and Gen Alpha are second nature. But if you’re a Millennial or Gen X still trying to figure out what “delulu” means (don’t worry, we’ve all been there), here’s a quick explainer before we go nose-first into the fragrance phenomenon sweeping through middle schools and high schools across the globe.

Gen Z refers roughly to those born between 1997 and 2012, while Gen Alpha is the next wave, kids born from 2013 onward. Yes, we’re talking tweens and even grade-schoolers here. Case in point: My nine-year-old daughter already knows more about fragrance than most grown adults. Being a perfume writer, I thought this was because she hears me talking about it all day, but my point is she knows which perfume smells like cookies, which one smells like summer, and which one is strong and lasts for days on her clothes. 

If you thought these generations were just glued to screens…

…you’d be half right. But something interesting is happening. As TikTok influencers rise in cultural influence, Gen Z and Gen Alpha are channeling their screen time into something unexpected: Perfume knowledge. And not just “this smells good” kind of knowledge, we’re talking nerdy breakdowns into notes, accords, sillage, projection, new exciting launches, and even niche fragrance houses. This whole movement has a name: Scentmaxxing or smellmaxxing. 

What Is Scentmaxxing?

At its core, scentmaxxing is about curating a personal fragrance identity. It’s about layering, selecting, and sometimes obsessing over the perfect combination of scents that speak to who you are or who you want to be, in that moment. It’s less about smelling good for others and more about smelling like you.

For these young fragrance enthusiasts, that means wearing a citrusy aquatic cologne to gym class, a vanilla-based gourmand to after-school hangouts, or a musky amber scent to feel a little older and more confident. Brands like Dior, Jean Paul Gaultier, and Tom Ford are seeing more teen and pre-teen buyers than ever before.

And yes, they absolutely know what sillage is. And projection. Probably better than most of us.

Why Is Scentmaxxing So Popular?

It’s all down to influencers. TikTok creators have made perfume education entertaining. They break down scent families, compare dupes, and share layering routines with their millions of followers. We know that scent is deeply tied to emotion and memory. For Gen Z and Gen Alpha, perfume is a way to reflect how they feel or how they want to feel. Whether it’s confident, cozy, playful, or powerful, there’s a scent to match. In many schools, scentmaxxing is the new bonding ritual. Students trade samples, compare scents, and even compare fragrance “notes” from one another. Compliments on how you smell? Instant clout.

We can’t wrap up this article without noting that scentmaxxing is part of a broader wave of “maxxing” trends, where people aim to optimize different aspects of themselves, whether it’s looksmaxxing (appearance), gymmaxxing (fitness), or now, scent. If you’re genuinely interested in self-improvement, you’ll find a treasure trove of content out there. Some of it is incredibly insightful… and some of it, well, not so much.

Want to see scentmaxxing in action? Just search the hashtag #scentmaxxing or #smellmaxxing on TikTok and prepare to be impressed. And fair warning: You might also want to clear your schedule. This rabbit hole is deep, addictive, and best explored on a day with no other plans.
