01 Overview

Craft the future of luxury fragrance.

L’Oréal Brandstorm is an international innovation competition for students. The 2026 mission, set with L’Oréal Luxe, asked teams to invent new fragrance products and experiences powered by creativity, technology, and bespoke service.

As UX designer and coordinator for Team Cree, I organized our research, turned survey results into product requirements, and shaped the concept into a pitch we delivered live to L’Oréal industry judges, placing competitively against university teams nationwide.

02 Ideation

One whiteboard, every idea.

We began by mapping everything a fragrance could be. Starting from the word “perfume,” the board branched into feelings, notes, ingredients, culture, and packaging, while side lists tracked our target audience, what they want, and materials for bottles and refills.

Our opening mind map: scent families and moods branch out from “perfume,” with notes on target users, wants, and bottle materials.

Two threads kept surfacing: people want scent that feels personal, and they increasingly care where ingredients come from. The concept lived where those two threads crossed.

03 Concept

What if fragrance helped restore nature?

The fragrance industry depends on resource-intensive crops and heavy packaging, while invasive plant species damage ecosystems and cost millions to manage each year. ReVerdi connects those problems: responsibly harvested invasive botanicals become the base notes of a personalized scent, and part of every sale funds ecosystem restoration.

Problem and opportunity: why a regenerative concept fits L’Oréal’s goal of 100% eco-designed products by 2030.

We chose YSL Beauty for its fashion-driven innovation and bold identity, a brand that could credibly lead regenerative luxury fragrance.

04 Survey research

Would people actually test their own skin?

Personalization was the riskiest assumption. Our concept asked customers to use pH strips, oil blots, and temperature strips, then share the results through an app. I designed a survey to test interest, willingness to use at-home tools, price tolerance, and privacy comfort.

72 / 75
were very or somewhat interested in a fragrance matched to their body chemistry
57%
would pay $50–$100; another 19% would pay $100–$150
75%
would feel more comfortable if data were encrypted and never stored
Responses coming in: privacy concerns, preferred personalization inputs, and comfort with encrypted data.

The privacy questions changed the product. Misuse of personal data and data privacy were the top concerns, and most people preferred personalization based on both physical skin tests and lifestyle questions. That pushed us toward a design where results stay on the customer’s side and only the formula is shared.

05 Experience design

In store, then at home.

In-store experience

  • Skin pH, oil-level, and temperature testing
  • Lifestyle and scent-preference consultation
  • Guided fragrance blending

At-home kit

  • Included testing materials
  • Modular invasive-botanical fragrance bases
  • Refillable glass bottle in recycled packaging

Companion app

  • Subscribe to a custom formula
  • Log at-home test results
  • Track KPIs for the business

06 Visualization

Making the bottle real enough to judge.

Judges needed to picture a YSL product, not a sketch. We modeled and lit the refillable bottle in Blender so the pitch could show material, weight, and finish.

Data, KPIs, and consumer validation, with the “Le Parfum” app concept used to measure success.

07 Pitch

Research into a story judges could follow.

My last job was turning months of notes and 75 survey responses into a narrative that fit the time limit: the problem, the opportunity for L’Oréal, how ReVerdi works, and the evidence that people want it. We delivered the pitch live to L’Oréal industry judges.

08 Reflection

Coordinating is a design skill.

Brandstorm was my first time leading research inside a team under a hard deadline. Keeping everyone working from the same evidence mattered as much as any screen. If we took ReVerdi further, I would prototype the at-home kit with real testers to see whether the skin tests feel fun or clinical, and design the app’s privacy controls as carefully as the bottle.
