Fortifies the microbiome. Stabilizes the barrier.

What it does

A jelly-textured serum that strengthens the skin barrier from within by supporting its microbiome. Lactobacillus ferment lysate — a clinically studied prebiotic — feeds the skin's resident microflora and reinforces its first line of defense. Hyaluronic acid and Sodium PCA add structural hydration, while the gel matrix forms a thin functional film that locks in the previous layers.

Key ingredients

  • Lactobacillus ferment lysate (prebiotic): nourishes the skin microbiome; reinforces barrier resilience.
  • Hydrolyzed hyaluronic acid + Sodium PCA: layered hydration.
  • Pogostemon Cablin (Patchouli) oil: balancing, soothing.

How to use

  1. After 0.3 BOOST.
  2. Apply 1–2 pumps; press into the skin until fully absorbed.
  3. Wait 60 seconds before applying 0.5 REPAIR.

Layer within the system

0.4 SEAL is the inflection point of the system — where the architecture moves from infusion to retention. By supporting the microbiome, it does what conventional occlusives cannot: it stabilizes the barrier biologically, not just physically.

Questions

What is a prebiotic in skincare?

Prebiotics nourish the beneficial bacteria that live naturally on healthy skin. A balanced microbiome is correlated with reduced sensitivity, better hydration retention and stronger barrier function.

Is it suitable for sensitive skin?

Yes. Dermatologically tested. Designed to reduce reactivity over time.

Does it replace a moisturizer?

No. It works in sequence — 0.5 REPAIR completes the system.
