Medik8 Crystal Retinal 24

Serums United Kingdom Approx. $94

The top of Medik8's retinal ladder, and the reason a ladder exists at all: you earn 24 by spending months at 3, then 6, then 10. Nobody should buy this one first. It sits on this shelf as the destination, which is worth being able to see from the bottom.

  • The strongest step of a system whose first step we also stock
  • An airless tube, because retinal is famously unstable in air
