Refining a value proposition and improving the global user experience at international level

Customer story: L'Oréal / Vichy

It helps users know more about their skin and take better care of it: people take a selfie and fill in some information about their skin profile to get a full skin aging diagnostic and product recommendation.
  • The main goal of the user research was to assess the value proposition and offered experience at international level.

Research and deliverables

Our UX researchers conducted 3 studies to ensure the end product would deliver consistent best-in-class value and experience to Vichy's users.

Phase 1: remote user testing of the experience

At home, each in their own country, from their own device, users had to undertake the entire experience on their own, from discovering the home page, taking a selfie, filling in their additional information, and finally finding out the diagnosis. They gave detailed feedback for every step of this experience.

Delivrables of the first phase

From this first phase, we delivered clear UX recommendations with a precise roadmap. The main insights were the global positive perception of the offer and expertise, and a need to fluidify navigation steps: fix blocking bugs, improve product details, optimize the path to purchase.

Phase 2: remote user testing of the optimized version and exploratory user interviews

With an updated prototype following the first study, the same protocol was used to compare the evolution of the experience and the subsequent perception of users.

Simultaneously, interviews with users were set up to first know more about their skincare habits and brand perception before using Skin Analysis. Then, users also had to go through the experience using the same path as study 1 and 2 and were asked about their perceptions of the experience. Finally, we assessed their perception of the Vichy Brand after having completed the experience.

Deliverables of the second phase

From the second phase we delivered analysis and UX recommendations based on the user test of the reworked prototype, and on the insights of the exploratory step.

  • There is still a good perception of the value proposal: the experience is globally perceived positively by users and leads to a strong interest in Vichy products while reinforcing the innovative perception of the brand.
  • UX recommendations went deeper into pain points details of the experience: rework age identification step, improve clarity of the results and solve technical problems when analyzing selfie and adding to cart.

That allowed us to integrate final optimizations before starting production.

L'Oréal's testimony on its experience with Ferpection

"Real experts of user testing. Each test result helps us make a quantum leap in tech product development with reliability, confidence and impact. A real pleasure to work with this no-stress-quick-and-efficient team. Even for complex studies (recruitment of samples with very specific and not very obvious profiles to find, or internationally) they provide. We love it."
