I heard the Shrek Pack was famous, so I bought it at Olive Young to try. Although it is a bit of a hassle to apply it, let it dry, peel it off, and wash it off, I definitely feel like my pores are shrinking, and the cooling sensation while wearing it makes me use it regularly. After using the pack, my skin definitely feels brighter, and I like that my skin temperature feels cooler. Unlike the name Shrek, it feels like a pack that actually improves and beautifies the skin. I plan to repurchase it once I finish this one.
