A message from one patient to another.
I know what it’s like to live in a cycle of “short-term skin fixes.” When I was first diagnosed with Psoriasis 20 years ago, I relied on steroids that worked for a few weeks, only for the disease to return even stronger. As the inflammation spread from my hands to my elbows and legs, it felt like my world was shrinking.
Everything changed when I stopped looking for a “magic cure” and started looking for my Psoriasis triggers. By focusing on my diet, my body activity, and my mental wellbeing, I finally took control.
Itchi isn’t a replacement for your Psoriasis medication; it’s the support system for your life. It is a way to run your own personal experiments to find your body’s unique inflammation triggers and find the lasting wellbeing we all deserve.
Why a product designer built a health app.
As a product designer, I kept looking for a tool that would let me run structured experiments on my own body, isolate one variable at a time, track my skin systematically, and actually read the results. Nothing like that existed for psoriasis patients.
Every feature in Itchi comes from living with this condition for two decades, not from a clinical study alone. The 30-day experiment structure, the breathing sessions, the step tracking, all of it is designed around one question: what is actually causing your flares?
Itchi is built in Helsinki, Finland. If you have questions, feedback, or want to share your own trigger story, write to hello@itchi.me. I read every message personally.
