This is a whitening/exfoliating treatment product from a popular Korean brand, IOPE. IOPE stands for Integrated effects Of Plant Extracts. I've been using this entire line since March & my skin's never looked better. This lotion is a lightweight treatment that contains 15% plant extracts plus AHAs. It is designed to go over your favorite moisturizer. Ever since using it (2 wks), I noticed that my skin appears brighter & more refined. The oil on my face has definitely reduced, and my self-tanner is more effective (no streaks!). I will keep using this product to see if the long-term results are just as beneficial!
