Bring Leather Back to Life
After cleaning and correction, leather needs more than surface care—it needs to be restored from within.
✨ What Y5 Does
Y5 includes the same correction steps as Y3, then continues further to restore moisture, flexibility, and internal strength.
2-LAYER EXPLANATION
1. Restores leather from contamination to full flexibility.
2. Begins with controlled cleaning and pH balancing to remove barriers, followed by hydration and fatliquoring to restore internal lubrication—
finishing with surface refinement for a natural feel.
SYSTEM FLOW
2.2 → 3.0 → 3.3 → 5.0 → B
Degreaser 2.2
Removes oils, residues, and contamination
Rinse 3.0
Balances pH and stabilizes leather
Hydrator 3.3
Reintroduces moisture evenly
Fatliquor 5.0
Restores internal lubrication
Conditioner B

WHEN TO USE Y5
✔ Leather is dry AND contaminated
✔ After long-term oil/wax use
✔ Stiff, dull, or lifeless leather
✔ When Y3 alone is not enough
WHEN NOT TO USE Y5
❌ Light maintenance → use Y4
❌ New leather → use Y2
⚠️ IMPORTANT DISTINCTION
Y3:
Targeted corrective reset
- focused
- localized
- problem-driven
Y5:
Full recovery process
- complete workflow
- structural restoration
- broader application
