From Our Founder
"IZUMI was created for those moments when the skin begins to change—and needs deeper support.
In my clinical experience, I often saw patients searching for renewal, but hesitant to use strong formulas that could compromise their barrier. I wanted to design a serum that encourages regeneration without overwhelming sensitive skin.
IZUMI works with the skin’s natural renewal cycle, helping improve firmness and resilience gradually. It is not about aggressive correction. It is about strengthening the skin over time.
For me, IZUMI represents longevity—care that supports your skin today while preparing it for tomorrow."
— Dr. Maria Urbani, M.D.
