We started with a simple mission: create skincare that works for everyone, regardless of skin type or tone. Our journey began in a small lab in Markham, where we spent years researching and testing formulations.
OUR STORY
Professional Skin Therapy. Finally, For Home.
byTheia was founded on a simple belief: clinically proven LED light therapy shouldn't require a spa appointment. Everyone deserves radiant, healthy skin on their own terms, in their own space.
WHERE WE STARTED
Born in Markham. Built for Every Skin Type.
Today, we're proud to offer products that combine cutting-edge technology with natural ingredients, all backed by rigorous testing and FDA approval.

We don't just sell beauty devices. We give people access to light— the kind that heals, regenerates, and restores. The kind that used to cost $200 a session.
WHAT WE STAND FOR
