Refuel

A chemical manufactured by Firmament, refuel replenishes the proteins and nutrients absorbed by Lyne tattoos, as well as very briefly slowing the degenerative process.
While its chemical composition is closely guarded by Firmament's legal teams, it is also a publicly sold product, making it accessible to the research teams of other companies. Nevertheless, none have been able to create any legally-dubious knockoffs to date.
It is commonly understood that Synthetics are give free refuel by the Firmament Corporation while they are growing up on the Compound, but have to buy their own once they move into the City proper. This is all hearsay, of course,
