Léoniaclean-beauty e-commerce / production case study

the custom Shopify build behind Léonia Paris.

A certified-organic French beauty brand's Shopify storefront — a bespoke theme plus the features Shopify can't do natively: a real account dashboard, loyalty and referral, gift-with-purchase, and a performance pass. Partners since 2021.

The system

the custom work on top of Shopify.

01

Bespoke Shopify theme

A custom Liquid theme built for a premium skincare brand — the bestsellers grid, product pages, mega-menu, editorial Journal and a French-first language switcher.

02

A real customer account

One condensed dashboard — orders, personal details, loyalty points and a referral insert — where Shopify hands you an order list and blocks editing the rest. The hard part, done properly.

03

Loyalty & referral

Loyalty-points balances pulled from a third-party app into the account page, and a sponsorship / referral flow so customers can bring in customers.

04

Gift-with-purchase

A threshold offer — a free product added automatically over a spend level (“lait corps offert dès 90€”) — built as custom cart logic, because Shopify does not offer it.

05

Diagnostic & storytelling

A skin-diagnostic journey that routes customers to the right routine, plus the certifications, testimonials and Journal that do a clean-beauty brand's storytelling.

06

Performance pass

Deferred scripts, lazy-loaded images and video, font-display swapped, explicit media dimensions, and heavy third-party plugins replaced with lightweight custom code.

Architecture

A production stack built for the work.
