I have extremely oily skin, but Jung Saem Mool's foundation was perfect for summer use! The coverage is flawless, and it adheres well to the skin. I use Fair Light, and it matched my complexion perfectly for those 'no-makeup makeup' days when I'm not going all out.
On dry days, like in winter, the foundation tended to look a bit patchy, which was disappointing. That's why I only used it during the summer months!
