Created by someone who understands Sensitive Skin
From Our Founder
"KIDO was created for those moments when you want visible change—but without compromising your skin barrier.
In my practice, I often saw patients afraid of brightening products. Many had experienced irritation, peeling, or sensitivity from aggressive formulas. I knew there had to be a more balanced approach.
KIDO was developed to refine tone progressively, using actives that support clarity while respecting sensitive skin. It is not about fast transformation. It is about steady, controlled improvement.
For me, KIDO represents confidence—the kind that comes from seeing your skin become clearer, calmly and consistently."
— Dr. Maria Urbani, M.D.
Founder, IKI Skin Care

Free from parabens, sulfates, and synthetic fragrances, KIDO combines well-studied actives in a lightweight texture designed for gradual, balanced refinement.
