How to Use NIHON
Created by someone who understands sensitive skin
From Our Founder
NIHON is one of the products closest to my heart because it represents patience, strength, and resilience — the very qualities I learned from living with sensitive skin.
When my skin barrier was damaged, nothing helped. Even the gentlest creams would sting or sit on top of my skin. I wanted to create something that didn’t just hydrate but truly repaired and restored comfort.
That’s how NIHON was born — a deeply nourishing balm that works with your skin, not against it. It’s rich but never greasy, powerful yet calm.
It reminds me that healing takes time, but with the right care, your skin can find its strength again.”
Maria, IKI Skin Care Founder
The Lab:
