What Makes ZK Serums Different?

Published on July 3, 2025 · By Dr. Katrina

Our formulas aren’t trends — they’re treatments. ZK Serums were developed through years of clinical research, with every ingredient hand-selected for dermatological performance and safety.

🧪 Why ZK is Different:

• ✓ Created by a board-certified medical doctor
• ✓ Tested on sensitive skin — not just “normal” skin
• ✓ Backed by peer-reviewed dermatological studies
• ✓ Focused on long-term skin health, not quick fixes
