KINS Serum Repair
KINS Serum Repair - 30ml
KINS Serum Repair is an advanced Japanese anti-aging serum designed to support mature skin experiencing dryness, loss of elasticity, dullness, and visible aging signs.
Built around the concept of balancing the skin microbiome, the formula uses carefully selected fermented ingredients and bacterial fermentation extracts to help strengthen and harmonize the skin ecosystem while supporting long-term skin health.
Unlike traditional harsh anti-aging treatments, this serum combines powerful yet gentle ingredients like bakuchiol — a plant-derived retinol alternative — with soothing and barrier-supportive components, making it suitable even for sensitive skin.
The lightweight serum absorbs comfortably into the skin, helping restore hydration, resilience, smoothness, and youthful radiance with consistent daily use.
Key Benefits:
- Helps improve skin elasticity and firmness.
