Scaling Evolus’ ordering experience from a single-product flow into a multi-product commerce system built for a growing injectable portfolio.

When Evolus expanded their product palette beyond Jeuveau®, its ordering experience needed to evolve with it. The existing portal had been designed entirely around a single product, from the dashboard and purchasing flow to pricing and checkout.

I worked with the Product team to rethink the experience for a growing injectable portfolio, introducing product discovery, multi-product ordering, cart functionality, and a pricing system capable of supporting different products and shared tier thresholds.

01 - The Challenge

A platform built around one product

Before Evolus expanded its product portfolio, the ordering experience was built entirely around Jeuveau®. There was no need for product discovery, comparison, or a traditional cart, the user entered the ordering flow with only one product available to purchase.

With the introduction of their new filler palette, Evolysse™, that model no longer worked. The portal needed to accommodate multiple products while remaining familiar to existing customers and supporting the complex purchasing and pricing rules behind each brand.

02 - Exploring a scalable commerce model

Bringing familiar e-commerce patterns into a B2B ordering experience

The Product team initially asked me to explore how established e-commerce experiences handled multi-product purchasing and translate those patterns into the Evolus ecosystem.

I reviewed common catalog, product-detail, cart, and checkout patterns and used those findings to create an initial proof of concept for the new ordering experience.

The concept introduced a dedicated product catalog, individual product pages, and clearer separation between browsing, configuring an order, and checkout- creating an architecture that could continue to scale as new products were added.

03 - Rethinking the cart

Supporting multi-product purchasing without interrupting the flow

Moving from one product to several also introduced something the previous experience had never needed: a true cart.

For the initial concept, I proposed a slide-in cart that gave users immediate confirmation when an item was added while keeping them within the shopping flow. It also created space for related products and made it easy to continue building an order without repeatedly moving between product pages and checkout, therefore creating an experience users are familiar with.

04 - Designing within product constraints

Evolving the existing order summary instead

As the concept evolved, the team decided to retain Evolus’ existing persistent order-summary model rather than move forward with the slide-in cart I had recommended.

That decision changed the interaction model, but not the underlying requirement: users still needed to understand an increasingly complex order containing products with different units, quantities, discounts, and pricing tiers.

I therefore adapted the multi-product experience around the persistent sidebar, redesigning it to provide a clear view of the products in the order, tier-based discounts, subtotal, savings, and estimated total throughout the purchasing journey.

05 - The hard part

Making bundled pricing understandable

Unlike Jeuveau®, the new filler portfolio introduced shared volume-based pricing across multiple products.

Customers could combine eligible Evolysse products to reach a quantity threshold and unlock a new pricing tier. However, reaching the same tier did not mean every product received the same unit price - each product still had its own price within that tier.

So the interface had to communicate three things simultaneously:

  • how many total syringes counted toward the customer's tier;

  • which tier they had currently unlocked and how close they were to the next one;

  • the individual price and savings associated with each product at that tier.

From a pricing table to a progress system

Rather than presenting pricing as a static list of numbers, I designed the tiers around progression. Customers could see where they currently sat, which tiers they had already unlocked, what remained ahead, and the additional quantity required to reach a better price.

06 - Checkout

One checkout for an increasingly complex order

The shift to multi-product ordering continued through checkout.

What had previously been a straightforward purchase of one SKU now had to account for combinations of products, different unit types, quantity-based discounts, tier upgrades, and total savings.

I redesigned the checkout experience so customers could verify the composition and pricing of their order without having to mentally reconstruct how each discount had been applied.

07 - Outcome

Building the foundation for a growing portfolio

The launch of Evolysse marked Evolus’ transition from a single-product company to a growing injectable portfolio.
The new ordering experience provided the digital foundation for that shift, supporting product discovery, mixed-product orders, shared pricing tiers, cart functionality and checkout across multiple products.

Following the launch, Evolysse generated $9.7M in its first commercial quarter and expanded to 4,000+ purchasing accounts, while the wider Evolus platform grew to 18,600+ purchasing accounts.
