About Us
RUDDI didn’t start in a lab — it started when our Co-Founder, Kristina was a child.
Growing up, she watched her mom struggle with rosacea and try product after product, only to end up using Nivea because it was the only thing that didn’t make her skin worse.
It didn’t fix the problem — it just didn’t burn.That idea stuck with Kristina.Years later, she was living with type 1 rosacea herself and hearing the same message: this is something you manage, not fix. Use “gentle” products that don’t really work, or “effective” ones that come with redness, irritation, and flare-ups.For a long time, she accepted that this was just how it was.Until she didn’t.Kristina spent two years studying about skin inflammation and learned that rosacea, eczema, dermatitis, and acne aren’t random — they’re immune responses, usually driven by more than one underlying issue. That understanding became the foundation of RUDDI.
