# BARRIER-LOCK MOISTURIZER
Post-Serum Barrier Repair for Peptide Routines
Role in the system: STEP 3 – LOCK
(Used after HA Base + Peptide Booster)
> Barrier-repair moisturizer designed for use after peptide serums to reduce moisture loss, calm the skin, and support stable peptide routines.

## WHAT THIS PRODUCT IS
A barrier-repair moisturizer designed specifically to be used after peptide serums.
It does not deliver peptides,
it does not act as a carrier,
and it does not interfere with peptide chemistry.
Its job is simple and critical:
👉 Stabilize the skin environment after peptides are applied.
---
## WHAT PROBLEM THIS SOLVES
High-signal peptide routines (GHK-Cu, SNAP-8, Matrixyl, KPV) often fail not because of the peptide, but because:
* the skin loses water too fast
* irritation builds up over days
* barrier stress shortens effective exposure
This product solves that by acting as a protective lock layer.
---
## WHAT IT DOES (REAL MECHANISM)
* Reduces moisture loss
Forms a barrier that slows water evaporation after serum.
* Calms & strengthens the skin barrier
Helps reduce irritation and sensitivity from active routines.
* Supports consistent peptide exposure
By keeping the skin stable, peptides already applied remain effective longer.
This is passive support, not active delivery.
---
## TEXTURE & FEEL
* cream to lotion texture (depending on variant used internally)
* spreads easily over damp serum
* non-stinging
* no active tingle
* leaves skin comfortable, not tight
---
## WHO SHOULD USE THIS
* anyone using peptide serums
* sensitive or acne-prone users needing barrier support
* copper peptide users (face or scalp margins)
* users experiencing dryness, redness, or “overactive skin” from actives
---
## HOW TO USE (SYSTEM LOGIC)
AM / PM Routine
1. Cleanser
2. HA Base (FLUX or PLUMP)
3. Peptide Booster Serum
4. BARRIER-LOCK MOISTURIZER
Use after serum.
Never mix peptides into this product.

## WHY THIS COMPLETES THE SYSTEM
Your ecosystem now has clear roles:
| Step | Product | Role |
| ---- | ---------------------------- | --------- |
| 1 | Cleanser | Prep |
| 2 | HA Base | Carrier |
| 3 | Peptide Booster | Signal |
| 4 | Barrier-Lock Moisturizer | Stabilize |
This prevents:
* irritation escalation
* inconsistent results
* user confusion
