The Prejuvenation Room

Everything the register will and will not say about treating a face that has not yet aged.

Issue No. 1Autumn 2026Evidence tiered

This room exists because the word prejuvenation is used commercially far beyond what its literature supports. The register's position is that the four interventions it borrows can be read honestly, and that the category itself cannot.

Nothing in this room applies a score to a face. Where an intervention has a trial, the trial is cited. Where it has a mechanism, it is labelled mechanistic. Where it is the house's opinion, it says so.

In this room

  • Sunscreen, and the only trial that has the shape of the promise.
  • Retinoids as repair, not as insurance.
  • Barrier care: a mechanism, and the limits of a mechanism.
  • Oral collagen: a small study read honestly.
