Research and deliverables

Our UX researchers conducted 3 studies to ensure the end product would propose the best value and experience to the Vichy's users.

Phase 1: Remote user testing of the experience

At home, from their own device, users had to realize the entire experience on their own, from discovering the home page, taking a selfie, filling their additional information, and finally finding out the diagnostic. They gave detailed feedback for every steps 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, but need to fluidify navigation steps : fix blocking bugs, improve product details, optimize path to purchase.

Phase 2: Remote user testing of the optimised version and exploratory user interviews

With an updated prototype following the study 1, the same protocol was used to compare the evolution of the experience and the consequent perception of users.

Simultaneously, interviews with users has been 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 asked about their perceptions of the experience. Finally, we assessed their perception of the Vichy Brand now that they have done the experience.

Delivrables 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 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 to integrate final optimisations before starting production.
