We’ve all been there—painful, contagious, and always showing up at the worst possible moment. First dates, big meetings, dream vacations—HSV-1 doesn’t check your calendar. And yet, 67% of the world carries it, but no one talks about it. That ends now.

We’re a team of engineers, designers, and cosmetic experts from Sydney, Australia—cold sore sufferers, just like you. We were done with the drama, the stigma, the never-ending cycle of messy creams and outdated fixes. So, we built something better.

LIGHT ON. DRAMA OFF.

It’s time to shed light on the problem—literally. No more cover-ups. No more silence. The answer? Light. But not just any light—Low-Level Light Therapy (LLLT), clinically proven to cut healing time by 50% and reduce outbreaks 12.5 times.

LLÏTSTICK. 

A first-of-its-kind, portable Low-Level Light Therapy (LLLT) device that’s clinically proven to accelerate recovery and reduce outbreaks. No mess. No stigma. Just science-backed relief that fits in your pocket.

Designed in Australia, inspired by millions worldwide. Because no one should have to hide their lips or dim their light.

COLD SO?
