A global skincare brand builds retention through its loyalty program “INKEY Insiders”

INKEY’s journey from growth to retention

The INKEY List is a UK-based brand simplifying science-led skincare.

After fast global growth, they needed a loyalty solution to keep retention and personalization at the heart of their strategy, without overloading their lean team.

They turned to LoyaltyLion to meet these key needs:

  • A loyalty platform that could scale globally
  • Deep expertise in customer retention
  • Tools to build loyalty in a competitive beauty market
  • Actionable insights to better serve their customers

How INKEY Insiders works

INKEY Insiders was launched in 2022 across four global regions to reward brand engagement and personalize the customer journey.

Key features:

  • Insider’s Prices: Member-only discounts
  • Double points on selected launches
  • VIP tiers: Early access for Stars, exclusive invites and gifts for Icons

Engagement through data and User Generated Content

To support personalized marketing, The INKEY List used LoyaltyLion’s custom activities to collect zero-party data while rewarding customers.

How it works:

  • Customers earn points for completing skin, hair, and breakout quizzes — plus 50 bonus points and a free product for joining INKEY Insiders
  • Quiz results trigger Klaviyo emails that nudge shoppers to return and redeem rewards
  • Reviews also earn points, with extra rewards for photo submissions to boost UGC

This strategy builds stronger relationships and powers personalized marketing — all without feeling transactional.

Inkey Quiz

Listening to our customers’ skin and hair-care needs with quizzes has brought us a fabulous wealth of zero-party data. It’s just one way our loyalty program has helped inform product development so we can better serve our customers.

Insiders Week: a launchpad for loyalty

INKEY Insiders Week, one of the company’s most successful loyalty initiatives, proves that exclusive rewards don’t just delight your best customers — they fuel growth.

What happened:

  • A week of Insider-only perks: double points on all purchases, random refunds, early access to new products, scratchcards in every order, and much more
  • Better benefits for higher tier members: site-wide discounts plus a free product (size dependent on tier) with every order 
  • 41% of total revenue was attributed to the program, loyalty’s highest-ever weekly contribution
  • Loyal members spent 3x more than non-members
  • Over double the number of program enrollments compared to a normal week
