Kiehl’s Builds London Plump Club Pop-Up With Heaps + Stacks

Heaps + Stacks reported 1.5 million in reach and 3,240 engagements for the activation. The event images show a large red smiley-face balloon, pink inflatable seating, Kiehl’s product posters and a branded claw machine, alongside guests interacting with the installations.

Putting the serum’s product story into physical form Kiehl’s UK describes CollaShot as a topical serum formulated with recombinant collagen polypeptides and rhamnose. The brand positions it around visible plumping and firmness.

The London pop up made that product language tangible through oversized, bouncy props and spaces where visitors could encounter the product rather than just see it on a shelf. The London project is distinct from the Venice, California, CollaShot pop up previously covered by RETAILBOSS.

That earlier Plump Apothecary emphasised skin analysis and service led discovery. The Plump Club used a different local format, with Heaps + Stacks combining consumer access and creator-friendly visual installations around the same serum launch.
