From the article: 

Los Angeles served as the location for the national launch of a beauty sheet mask infused with CBD oil from Denver-based CoSo Beauty. The mask was unveiled at a January lunch at Ocean Prime in Beverly Hills by brand co-founders Jae Lee and his wife, Katy Lee.

The couple wanted to use Korean beauty technology and combine it with hemp-derived CBD oil. Jae Lee, who grew up in Colorado, had been successfully using CBD for joint pain and sleep.
