The Overnight Renewal Edition

The long, quiet night

Skin does most of its repair after dark. This box gathers the three nightly gestures, doubled — Saisei to mend, Mugen to seal, and bio-cellulose veils for the nights that asked too much of the day.

Mechanism of Action

How it works.

Sleep is when transepidermal water loss peaks and basal repair runs strongest. Saisei lays the repair signal; Mugen's anhydrous seal stops the night's water loss without occluding heat; the bio-cellulose veil is held for the harder nights — long flights, late laser, hard weather. Three objects, one night.

Part of the Junsui Ritual Editions collection. Smaller collections built around a single intention — sun, season, a particular kind of skin. Same clinical heart, dressed for a different ritual.

Protocol

How to use.

  1. 01

    Cleanse. A pearl of Saisei, pressed across face and neck.

  2. 02

    A pea of Mugen, warmed in the palms, laid over as the final seal.

  3. 03

    On the harder nights — apply a bio-cellulose mask between the two, for twenty unhurried minutes.

  4. 04

    Sleep. The skin does the rest.
