Youn Chang - Founder and CEO of OJOOK

Youn Chang

Founder and CEO

Formerly at Glossier, Apple


“Our products will not end up in landfills. They are thoughtfully made for the body, mind and nature with inspiration from generational knowledge without compromising efficacy or our values.”


After consumer product executive Youn Chang became a mother, her sense of urgency on wellness and sustainability shifted. What she knew intellectually became what she believed in her heart, and previous nice-to-haves became must-haves for her daughter and future generations. 


Youn decided to launch a brand that would bring her knowledge on Eastern wellness philosophy to the U.S. - a philosophy that teaches wellness as cumulative habits and daily rituals with a long-term horizon rather than quick fix solutions. OJOOK was born with Youn's vision to transform mindless routines into mindful rituals that create harmony between the mind, body, and environment.

“I joined OJOOK with hopes of developing products that learn from nature’s best design."


Healthcare professionals constantly strive to achieve the best outcomes for their patients. Beyond the clinic, advances in science and a better understanding of nature has enabled caregivers to develop innovative ways to improve health. Consumers are becoming more aware of what goes into each product they use and how it impacts both their health and the environment.


Having studied Biomimicry in college, Dr. Kim has always been inspired by elements of nature solving complex human problems. Developed over millennia, nature often provides the best sustainable design and is one of the best models for developing treatments and products that promote health.
