Katrine Marso

The brief

Katrine Marso is a premium skincare brand with a dermatological positioning, and skincare at that level sells on trust before it sells on product. The brand needed a complete Shopify store that could carry elegant, minimal storytelling and educate the customer, then convert that education through a personalized skin-analysis experience. And it had to work in two languages, English and French, from day one.

What we did

We designed and developed the store on a customized premium theme, with the homepage and PDPs built around the brand’s minimal, editorial look, ingredient and product sections doing the education work, and about and transparency pages carrying the trust story.

The centrepiece is the personalized skin-analysis quiz. It runs on logic jumps and conditional flows, so the questions adapt to the answers, and it lands on custom result pages that explain the recommended ingredients as well as the products. From the results, an automated bundle-to-cart flow assembles the routine in one step, the customer goes from diagnosis to a filled cart without hunting through collections.

Retention got built in rather than bolted on later: a loyalty and rewards programme, subscriptions with customer profile setup, and quantity-break bundling on the catalogue. The quiz, loyalty, subscription, and email apps were integrated and wired together through Zapier so the data flows without manual glue. The whole store shipped bilingual (EN/FR), mobile-optimized, with CRO-focused UX decisions throughout, and closed with QA before launch.

Why it mattered

A skincare routine is a considered, repeat purchase, and the brands that win it own the recommendation moment. The quiz gives Katrine Marso exactly that: instead of a shopper guessing between products, the store diagnoses, explains, and assembles the routine itself, then the subscription and loyalty layer keeps the relationship after the first order. Doing it bilingual from launch means the French-speaking market gets the full experience, not a translated afterthought.
