PS: When you do go back to Korea, what's the first thing you do, whether it's somewhere you go for a facial or a product that you snap up?
SL: We do a couple of things we love, from beauty hunting in the streets to seeing what the latest trends are. One of those beauty hotspots is our friend Unistella's [salon], who is nail artist who created glass nails. She's always a source of inspiration, as well.
SL: We always get facials. And we're always on a hunt for the latest facials — the latest technology with facials, but also the treatment approach. We were inspired by how Korean facials always incorporate hydration, extraction, exfoliation and soothing. We wanted to combine all of that, and that was actually a source of inspiration for our creation of the Watermelon Glow Sleeping Mask, which is why we combined hydration, exfoliation to one jar.
