Meet Our Founder

Jinmin Lee suffered from serious acne and she had used various brands creams to treat it but the condition has become worse and her skin has become very sensitive as a side effect of medications to a point where it would sting even to wash her face.

After reading a report from Europe about how the use of chemically derived synthetic ingredients has a high likelihood of disrupting the skin’s natural processes, and that applying exclusively naturally derived compounds can help treat skin symptoms. She searched for natural skincare brand that would help with her condition and came across a Germany brand named LOGONA. She then started distributing LOGONA in Korea and eventually became the President of the LOGONA Korea.

isoi was founded in 2009 by CEO Jinmin Lee after working in the natural skincare industry for years and realizing that the key to good skincare was not just mixing the natural ingredients but the technology in mixing them.

“Just by adding naturally derived ingredients doesn’t make a difference on the skin,but combined with our technology, isoi has advanced both the application and performance of natural skincare products.”
