Founder & Brand Ambassador

Moonsun Chai made this brand for the skin she was born into.

A chronic sensitivity left her skin reactive, inflamed, and exhausted — something she feared passing to her children. When she found that an ancient Korean herb, white dandelion, calmed what modern products could not, she began a twelve-year search to translate it into science.

“I didn’t want another product. I wanted the one I wish my mother had given me.”
