ICYMI, part of the big deal about K-beauty is achieving a "glass skin" look. You know, ultra smooth, dewy skin with so much of a glow from within that you almost appear shiny, but not in a greasy way. Considering that, Peach & Lily's Glass Skin Refining Serum ($39) had me at the name alone. Truthfully though, when you're diving head first into this many hydrating, glow-promoting products at once, it's hard to decipher which is doing the most legwork, but they do appear to work well as a team.
